ws at z=1.4−3.8\n\nSpeaker: Discussion Leader Gene Leung\, University of C
alifornia\, San Diego\n\nEach week\, we hold a relatively informal seminar
/discussion series in Peyton Hall with an emphasis on extra-galactic and l
arge-scale structure astrophysics. During Galread a leader/visitor present
s a recent paper to the discussion group. The PDF of the paper is projecte
d onto a large screen\, and a guest explains the paper\, section by sectio
n\, in greater detail than may be explained within the text of the article
. To aid with discussion\, only the article PDF is presented -- no powerpo
int-style slides. Galread discussions are very friendly and interactive. I
f you would like to present at Galread\, please contact Andy Goulding (gou

DESCRIPTION:Topic: Furstenberg sets in finite fields\n\nSpeaker: Zeev Dvir\
, Princeton University\n\nVideo: https://video.ias.edu/csdm/2019/1028-Zeev
Dvir\n\nA (k\,m)-Furstenberg set K in F^n\, where F is a finite field\, is
a set such that any k-dimensional subspace of F^n can be shifted so that
it intersects K in at least m points. Such sets generalize in a natural wa
y finite field Kakeya sets (in which k=1\, and m=|F|)\, whose study has re
sulted in many applications\, including in theoretical computer science. T
he main question is how small can such a set K be. While the polynomial me
thod gives a complete answer to this question when k=1 (i.e.\, when K inte
rsects lines in all directions)\, it fails completely for larger values of
k. Until recently\, the only bound for general k and m was given by Ellen
berg and Erman using scheme theoretic techniques. In this talk I will disc
uss a new result (joint with Manik Dhar and Ben Lund) that give improved (
and in some cases tight) upper bounds on the size of Furstenberg sets for
general k and m using completely elementary arguments.

DESCRIPTION:Topic: Sparse matrices in sparse analysis\n\nSpeaker: Anna Gilb
ert\, University of Michigan\; Member\, School of Mathematics\n\nVideo: ht
tps://video.ias.edu/members/2019/1028-AnnaGilbert\n\nIn this talk\, I will
give two vignettes on the theme of sparse matrices in sparse analysis. Th
e first vignette covers work from compressive sensing in which we want to
design sparse matrices (i.e.\, matrices with few non-zero entries) that we
use to (linearly) sense or measure compressible signals. We also design a
lgorithms such that\, from these measurements and these matrices\, we can
efficiently recover a compressed\, or sparse\, representation of the sense
d data. I will discuss the role of expander graphs and error correcting co
des in these designs and applications to high throughput biological screen
s. The second vignette flips the theme\; suppose we are given a distance o
r similarity matrix for a data set that is corrupted in some fashion\, fin
d a sparse correction or repair to the distance matrix so as to ensure the
corrected distances come from a metric\; i.e.\, repair as few entries as
possible in the matrix so that we have a metric. I will discuss generaliza
tions to graph metrics\, applications to (and from) metric embeddings\, an
d algorithms for variations of this problem. I will also touch upon applic
ations in machine learning and bio-informatics.

talk I will describe joint work with D. Alonso-Orán and A. Córdoba where
we extend a result\, proved independently by Kiselev-Nazarov-Volberg and C
affarelli-Vasseur\, for the critical dissipative SQG equation on a two dim
ensional sphere. The proof relies on De Giorgi technique following Caffare
lli-Vasseur intermingled with a nonlinear maximum principle that appeared
later in the approach of Constantin-Vicol. The final result can be paraphr
ased as follows: if the data is sufficiently smooth initially then it is s
mooth for all times.

DESCRIPTION:Topic: Solar Interiors\, Helioseismology and Neutrinos\n\nSpeak
er: Aldo Serenelli\, Institute of Space Sciences\n\nFor more than 20 years
helioseismology\, the study of solar oscillations\, has provided an exqui
site picture of the solar interior structure. However these oscillations\,
which are standing acoustic waves in the solar interior\, have diminishin
g amplitudes towards the deep interior and render a blurred picture of the
solar innermost core\, where most nuclear reactions take place and neutri
nos are produced. During the last decade\, after the discovery of neutrino
oscillations\, solar neutrino experiments such as SuperKamiokande\, SNO a
nd more recently Borexino have continued to develop and improve the accura
cy and precision of measurements solar neutrino fluxes. Helioseismic and n
eutrino constraints offer complementary views of solar interiors and open
up the best possibilities to date for testing solar (and stellar) evolutio
n theory as well as for using the Sun a laboratory for particle physics. T
he talk will first review the current status of (standard) solar modeling
in the context of helioseismic constraints\, and discuss where problems an
d uncertainties lie. About the latter\, some emphasis will be placed on re
cent calculations and experiments of radiative opacities that impact solar
and stellar modeling. The second part of the talk will present results of
solar neutrino experiments\, focusing on Borexino's capabilities to perfo
rm solar neutrino spectroscopy\, and the constraints on solar interior mod
els that can be obtained. The third part of the talk will briefly discuss
the relevance of solar model uncertainties for evolution of low mass stars
and the uncertainties in determination of stellar properties based on ast
eroseismic results might be affected.

Speaker: Baurzhan Mukhametzhanov\, Member\, School of Natural Sciences\, I
AS\n\nWe analyze modular invariance drawing inspiration from tauberian\nth
eorems. Given a modular invariant partition function with a positive\nspec
tral density\, we derive lower and upper bounds on the number of\noperator
s within a given energy interval. They are most revealing at high\nenergie
s. In this limit we rigorously derive the Cardy formula for the\nmicrocano
nical entropy together with optimal error estimates for various\nwidths of
the averaging energy shell. Finally\, we identify a new universal\ncontri
bution to the microcanonical entropy controlled by the central\ncharge and
the width of the shell.

DESCRIPTION:Topic: The Role of the Host Star in Shaping Planetary System Ar
chitectures\n\nSpeaker: Chris Spalding\, Yale University\n\nThe census of
extrasolar planets detected continues to grow well into the thousands. Thu
s set of exoplanetary systems have emerged as exhibiting large orbital mis
alignments with respect to both other planets in the system\, and with res
pect to the host star's spin axis. Moreover\, most planets detected reside
on orbits substantially closer to their host stars than Mercury sits to t
he Sun. In contrast\, our Solar system exhibits small inclinations and the
Sun's spin axis is relatively well-aligned. In this talk\, I explore the
hypothesis that the ultimate 3-dimensional architectures of planetary syst
ems is largely set by physical mechanisms playing out during the opening 1
0-100 million years of planetary system evolution. I will show how the ste
llar quadrupole moment of young stars may destabilize planetary systems\,
and how the young Solar wind can have played a role removing material from
the innermost Solar system. I discuss tests of these hypotheses promising
to emerge within upcoming datasets\, and important lessons that exoplanet
ary characterization has revealed about our own Solar system's history.

em? Can you really?\n\nSpeaker: Sara Tukachinsky\, Member\, School of Math
ematics\n\nVideo: https://video.ias.edu/members/2019/1104-SaraTukachinsky
\n\nOpen Gromov-Witten (OGW) invariants should count pseudoholomorphic map
s from curves with boundary to a symplectic manifold\, with various constr
aints on boundary and interior marked points. The presence of boundary pos
es an obstacle to invariance. In a joint work with J. Solomon (2016-2017)\
, we defined genus zero OGW invariants under cohomological conditions.The
construction is rather abstract. Nonetheless\, in a recent work\, also joi
nt with J. Solomon\, we find that the generating function of OGW has many
properties that enable explicit calculations. Most notably\, it satisfies
a system of PDE called open WDVV (Witten-Dijkgraaf-Verlinde-Verlinde) equa
tion. For the projective space\, this PDE generates recursion relations th
at allow the computation of all invariants. Moreover\, the open WDVV can b
e reinterpreted as an associativity of a suitable version of a quantum pro
duct. No prior knowledge of any of the above notions will be assumed.

DESCRIPTION:Topic: Chaotic and Thermodynamic Properties of two Coupled Sach
dev-Ye-Kitaev Models\n\nSpeaker: Jacobus Verbaarschot\, Stony Brook Univer
sity\n\nThe SYK Model was originally introduced as a random matrix model f
or the nuclear interaction that also describes the exponential rise of the
spectral density known as the Bethe formula. Exactly this behavior is the
hallmark of the Schwarzian action\, the low energy limit of the SYK model
\, which is the main reason for the excitement this model has brought to t
he field of Quantum Gravity. Another phenomenon in chaotic many-body quant
um systems is the existence of collective excitations. Remarkably\, they a
re present in the Maldacena-Qi model of two SYK models coupled by a spin-s
pin interaction\, which describes a phase transition between two black hol
es and a thermal phase. The collective state is the ground state which is
close to a Thermo-Field Double state. We find that for systems that can be
studied numerically\, the wave functions of the ground state show substan
tial deviations from the Thermo-Field Double state\, which suggests a non-
uniform convergence to this state in the limit of a large number of partic
les. The main topic of this talk is the discussion of the thermodynamical
and spectral properties of the Maldacena-Qi Model. We find a transition fr
om Poisson statistics in the tail of the the spectrum to RMT statistics at
higher energies\, when we separate the Hamiltonian according to the spin
mod 4 symmetry. We relate this order-chaos transition to the Hawking-Page
phase transition.

\n\nSpeaker: Catherine Cannizzo\, Simons Center for geometry and physics\n
\nWe will discuss work from https://arxiv.org/abs/1908.04227 on a homologi

how the result fits into the broader framework of HMS examples. Then we w
ill describe the geometric construction of the mirror. Finally we will see
the algebraic result on homogenous coordinate rings\, i.e. the HMS result
on the level of cohomology. The method involves first considering mirror
symmetry for the 4-torus\, then extending to a correspondence between a hy
persurface genus 2 curve and a mirror Landau-Ginzburg model with fiber the
mirror 4-torus. This is work from my thesis under my advisor Professor De

DESCRIPTION:Topic: Born-Infeld Electrodynamics at One-Loop\n\nSpeaker: Call
um Jones\, University of Michigan\n\nThe Born-Infeld model is an effective
field theory of central importance describing the low-energy dynamics of
massless gauge bosons on the world-volume of D-branes. Though it is in man
y ways an exceptional model of nonlinear electrodynamics\, several aspects
of the physics of the Born-Infeld model remain mysterious. In this talk I
will explain how aspects of the model\, obscured in the traditional formu
lation of Lagrangian field theory\, are clarified by directly studying the
on-shell S-matrix. In particular in 3+1-dimensions\, classical Born-Infel
d has an electromagnetic duality symmetry which manifests in tree-level sc
attering amplitudes as the conservation of a chiral charge. Whether this c
onservation law can be preserved under perturbative quantization is presen
tly unknown. Using modern scattering amplitudes techniques\, we have initi
ated a study of the S-matrix of Born-Infeld at one-loop. I will describe h
ow generalized unitarity together with supersymmetric decomposition can be
used to explicitly calculate infinite classes of one-loop amplitudes\, an
d explain how the results are consistent with the existence of a quantum e
lectromagnetic duality.

DESCRIPTION:Topic: The Giant Molecular Cloud Lifecycle Under the Influence
of Galactic Dynamics\n\nSpeaker: Sarah Jeffreson\, International Max Planc
k Research School for Astronomy & Cosmic Physics at the University of Heid
elberg\n\nThe giant molecular cloud (GMC) lifetime places an upper bound o
n the local time-scale for star-formation\, linking cloud- and sub cloud-s
cale physics to galaxy-scale trends in the star formation rate. Recent obs
ervations reveal environmentally-driven trends in GMC properties (e.g. sur
face densities\, velocity dispersions\, and turbulent pressures)\, demandi
ng a systematic\, predictive theory of the GMC lifecycle across the parame
ter space of observable star-forming environments. I will present an analy
tic theory for GMC lifetimes set by the galactic-dynamical time-scales of
the interstellar medium\, dependent on just three sets of observables: the
rotation curve\, surface densities and velocity dispersions of the host g
alaxy. I will compare and contrast these predictions with a statistical sa
mple of simulated GMCs across three isolated disc galaxies\, modelled usin
g the hydrodynamical\, moving-mesh code Arepo. My simulations incorporate
the features required to accurately model star formation and the influence
of stellar feedback on the ISM\, including ISM chemistry\, a stochastic t
reatment of star formation\, mechanical supernova feedback\, and pre-super
nova feedback from HII regions. As such\, I will (1) examine the nature of
the relationship between key GMC properties and the galactic-dynamic envi
ronment\, and (2) investigate the influence of star formation feedback in
truncating the GMC lifetime\, relative to the dynamical prediction of the
analytic theory. I will also present a comparison of my theoretical result
s to pioneering observational data currently obtained with ALMA. Together\
, this combination of analytic\, numerical and observational results show
that the galactic dynamic environment plays a crucial role in determining
GMC lifecycles and thus the star formation rates of their host galaxies.

the 1960's\, Burgess proved a subconvexity bound for Dirichlet L-functions

sterdam\n\nJets are fascinating objects which often travel over distances
hundreds of billions the size of their launching region near the black hol
e. Using GRMHD simulations\, I will show how a jet\, collimated by its sur
roundings\, accelerates (and decelerates) for over five orders of magnitud
e in distance while exhibiting flow instabilities\, with significant conse
quences for the jet morphology. Closer to the black hole\, the complexity
of possible misalignment between the accretion disk and the black hole spi
n direction also brings about interesting morphological changes in the jet
\, with exciting implications for the Event Horizon Telescope black hole i
mages of the galaxy M87 as well as for our Galactic center.

DESCRIPTION:Topic: From Symmetries to Cosmological Observables: New Soft Th
eorems for Cosmological Correlators\n\nSpeaker: Luca Santoni\, Columbia Un
iversity\n\nTests based on model-independent predictions and non-perturbat
ive results relying on symmetries\, that go beyond explicit realizations o
f inflation and the linear or quasi-linear regime of perturbation theory\,
are of particular relevance in cosmology. One major example is given by c
onsistency conditions for cosmological correlators. Solely based on the sp
ontaneous breaking of non-linearly realized symmetries\, they are Ward ide
ntities connecting a squeezed (N+1)-point correlation function\, where one
of the momenta is taken to be ‘soft’\, to an N-point function. One notabl
e feature is that of being model-independent and non-perturbative. Further
more\, they are particularly useful from an experimental point of view bec
ause they constrain the observables directly and provide a direct connecti
on between the theory and the data. During the talk\, I will show how to g
eneralize the construction of the Weinberg’s adiabatic modes and the stand
ard consistency conditions for cosmological correlators to situations wher
e extra symmetries (in particular\, a shift symmetry) or additional fields
are at play in the early Universe\, and I will discuss possible interesti
ng implications at both theoretical and observational level.Organizers are
Jo Dunkley\, Princeton University\, and Matias Zaldarriaga\, Institute fo
r Advanced Study. The lunch will be held either at Princeton University or
the Institute for Advanced Study. Check the calendar for the meeting loca
tion. This week's meeting is at Princeton University. Attendees can bring
lunch.

DESCRIPTION:Topic: Testing Gravity with Cosmology: Efficient Simulations\,
Novel Statistics and Analytical Approaches\n\nSpeaker: Georgios Valogianni
s\, Cornell University\n\nIn the era of precision cosmology\, a wide range
of cosmological surveys\, such as the LSST\, DESI\, Euclid and WFIRST wil
l precisely probe the large-scale structure of the universe\, shedding lig
ht on the nature of the dark sectors. This will be an unprecedented opport
unity to constrain theoretical alternatives to dark energy\, such as model
s that consider modifications to general relativity. In order to fully uti
lize the wealth of incoming data\, however\, theoretical predictions of st
ructure formation in such alternative scenarios are necessary\, proven to
be particularly challenging to obtain\, due to the increased phenomenologi
cal complexity that is introduced. In this talk I will show how these chal
lenges can be overcome\, employing a combination of analytical perturbativ
e techniques\, hybrid N-body simulations and novel statistics\, that will
allow efficient and robust predictions of potential deviations from ΛCDM\,
which will confront the next stage of cosmological observations.

DESCRIPTION:Topic: S-matrix Bootstrap for Effective Field Theories\n\nSpeak
er: Joao Penedones\, École polytechnique fédérale de Lausanne\n\nI will ex
plain how the S-matrix Bootstrap for massless particles can be used to con
strain the space of Effective Field Theories (EFT). In particular\, I will
discuss the S-matrix bootstrap for massless particles in unitary\, relati
vistic two dimensional quantum field theories. In the context of flux tube
physics\, this allows us to constrain several terms in the S-matrix low e
nergy expansion or -- equivalently -- on Wilson coefficients of several ir
relevant operators showing up in the flux tube effective action. The S-mat
rices living at the boundary of the allowed space exhibit an intricate pat
tern of resonances with one sharper resonance whose quantum numbers\, mass
and width are precisely those of the world-sheet axion previously propose
d. Finally\, I will present work in progress on pion scattering amplitudes
and the chiral Lagrangian. The general method should be extendable to oth
er massless S-matrices including gauge and gravity theories.

\nSpeaker: Mike Usher\, University of Georgia\n\nVideo: https://video.ias.
edu/sympdynageo/2019/1111-MikeUsher\n\nI will explain how coisotropic subm
anifolds of symplectic manifolds can be distinguished among all submanifol
ds by a criterion ('local rigidity') related to the Hofer energy necessary
to disjoin open sets from them. This criterion is invariant under symplec
tic homeomorphisms\, leading to a simplified proof of the Humiliere-Lecler
cq-Seyfaddini theorem that a symplectic-homeomorphic image of a coisotropi
c submanifold that is smooth is coisotropic. Moreover much of this picture
extends to the contact context\, allowing one to extend the class of C^0-
limits of contactomorphisms which are known to map Legendrian submanifolds
to Legendrian submanifolds.

point processes\n\nSpeaker: Thomas Leblé\, Member\, School of Mathematics
\n\nVideo: https://video.ias.edu/analysis/2019/1111-ThomasLeblé\n\nThe pat
h between two measures in the sense of optimal transport yields the notion
of *displacement interpolation*. As observed by R. McCann\, certain funct
ionals that are not convex in the usual sense are nonetheless *displacemen
t convex*. Following an idea of A. Guionnet\, we define a notion of displa
cement convexity at the level of point processes seen as measures on \R^{\
Z}\, and use it to prove that a certain free energy functional\, arising i
n Hermitian random matrix theory has a unique minimiser. This tells us som
ething about certain systems of particles in 1d. Joint work with M. Erbar
and M. Huesmann.

DESCRIPTION:Topic: CHIME: The Canadian Hydrogen Intensity Mapping Experimen
t\n\nSpeaker: Kendrick Smith\, Perimeter Institute\n\nVideo: https://video
.ias.edu/puias/2019/1112-KendrickSmith\n\nCHIME is a new interferometric t
elescope at radio frequencies 400-800 MHz. The mapping speed (or total sta
tistical power) of CHIME is among the largest of any radio telescope in th
e world\, and the technology powering CHIME could be used to build telesco
pes which are orders of magnitude more powerful. Recently\, CHIME started
finding new fast radio bursts (FRB's) at an unprecedented rate\, including
new repeating FRB's. Understanding the origin of fast radio bursts is a c
entral unsolved problem in astrophysics\, and we anticipate that CHIME's s
tatistical power will play an important role in solving it. In this talk\,
I'll give a status update on CHIME\, with emphasis on FRB's.

DESCRIPTION:Topic: Fast IRLS Algorithms for p-norm regression\n\nSpeaker: S
ushant Sachdeva\, University of Toronto\; Member\, School of Mathematics\n
\nVideo: https://video.ias.edu/machinelearning/2019/1112-SushantSachdeva\n
\nLinear regression in L_p-norm is a canonical optimization problem that a
rises in several applications\, including sparse recovery\, semi-supervise
d learning\, and signal processing. Standard linear regression corresponds
to p=2\, and p=1 or infinity is equivalent to linear programming. Generic
convex optimization algorithms for solving p-regression are slow in pract
ice. Iteratively Reweighted Least Squares (IRLS) is an easy to implement f
amily of algorithms for solving these problems that has been studied for o
ver 50 years. However\, these algorithms often diverge for p > 3\, and sin
ce the work of Osborne (1985)\, it has been an open problem whether there
is an IRLS algorithm that is guaranteed to converge rapidly for p > 3. We
propose p-IRLS\, the first IRLS algorithm that provably converges geometri
cally for any p in [2\, infty). Our algorithm is simple to implement and i
s guaranteed to find a high accuracy solution in a sub-linear number of it
erations (roughly sqrt(dimension)*log 1/error). Our experiments demonstrat
e that it performs even better than our theoretical bounds\, beats the sta
ndard Matlab/CVX implementation for solving these problems by 10–50x\, and
is the fastest among available implementations in the high-accuracy regim
e.

DESCRIPTION:Topic: Numerical Modeling of Star Formation and Feedback in Nuc
lear Rings\n\nSpeaker: Sanghyuk Moon\, Seoul National University\n\nNuclea
r rings are compact ring-like structures often found in central regions of
disk galaxies. They are known to be present in 20% of nearby disk galaxie
s\, among which 80% are barred. Nuclear rings in strongly barred galaxies
are most likely to be formed by rapid gas infall due to gravitational torq
ue. Considering the fact that the gas is trapped in the nuclear ring and t
urns into stars\, it is important to understand how fast can star formatio
n take place in nuclear rings and how the star formation rate is related t
o the inflow rate\, in order to get a multi-scale view of the black hole f
eeding process. Star formation in nuclear rings deserves attention on its
own. The typical star formation rate is on the order of one solar mass per
year\, which sometimes comparable to the star formation rate of an entire
galaxy. The high star formation rate and the compactness of nuclear rings
imply that they are potential sites of pseudobulge formation. At the extr
emities\, they may be able to drive massive outflows energized by supernov
ae\, producing galactic winds that we see today in M82\, for example. Desp
ite an importance of star formation and feedback occurring in nuclear ring
s\, detailed investigation has been challenging in both observation and si
mulation\, partly because of its compactness\, which requires high observa
tional and/or numerical resolution. To understand how star formation proce
eds and how feedback regulates star formation in nuclear ring environment\
, we have built a numerical testbed especially tailored for nuclear rings.
In contrast to global galaxy-scale simulations\, our model enables well-c
ontrolled experiments to be performed with high resolution\, by modeling t
he bar-driven mass inflow as an input while concentrating only on the nucl
ear ring region. In this talk\, I will introduce nuclear rings in a contex
t of large-scale fueling process\, underlining an importance of understand
ing star formation therein. After describing our model and numerical metho
ds\, I will present outcomes of our numerical experiments and discuss the
implications\, limitations\, and future directions.

DESCRIPTION:Topic: Star Cluster Populations: The Link Between Star Formatio
n and Galaxy Formation\n\nSpeaker: Michael Fall\, Space Telescope Science
Institute\n\nThis talk presents a general picture of star cluster populati
ons\, from their formation in the clumpy ISM to their eventual dissolution
in the smooth stellar field. The picture is general or unified in the sen
se that it encompasses most traditional categories of star clusters: assoc
iations\, open clusters\, populous clusters\, globular clusters\, etc. The
key element of this picture is the mass function of clusters (spectrum of
cluster masses) and its time (age) dependence\, or equivalently\, the joi
nt distribution of masses and ages. HST observations have revealed some re
markable similarities in the mass-age distribution of clusters in differen
t galaxies\, analogous to similarities in the stellar mass function (IMF).
This talk presents physical explanations for these observations.

DESCRIPTION:Topic: Diffuse Galaxies As a Probe for Dark Matter\n\nSpeaker:
Shany Danieli\, Yale University\n\nLow mass galaxies provide an essential
testing ground for theoretical predictions of cosmology. They dominate the
counts in the Local Group and have high mass-to-light ratios\, making the
m ideal for studying dark matter on small scales. Recent advances in teles
cope instrumentation have opened a new window into the population of such
low surface brightness galaxies. In this talk\, I will present recent resu
lts from the Dragonfly Telescope\, which has identified large numbers of l
ow surface brightness galaxies beyond the Local Group and discuss its cont
ribution and potential in extending our ability to test LCDM on small scal
es. I will discuss the recently identified population of ultra-diffuse gal
axies (UDGs) that holds the promise of new constraints on low mass galaxie
s dynamics\, as their spatial extent and often significant globular cluste
r populations provide probes on spatial scales where dark matter should do
minate the kinematics. I will also discuss the dynamics of two UDGs that s
eems to lack most\, if not all\, of their dark matter. I will finish by pr
esenting our strategy for finding low surface brightness galaxies as part
of the recently completed Dragonfly Wide Field Survey\, covering 330 sq. d
eg.\, in the GAMA and Stripe 82 fields.

DESCRIPTION:Topic: An Independent Determination of the Hubble Constant Base
d on the Tip of the Red Giant Branch\n\nSpeaker: Rachael Beaton\, Princeto
n University\n\nThe value of the Hubble constant (H0) continues to be an a
ctive topic in observational astronomy and many teams are now presenting r
esults at comparable precision. Taken together\, there is evidence for a s
ystematic discrepancy between these local measurements and measurements ti
ed to the Cosmic Microwave Background. I will describe\, in detail\, the k
ey results from the Carnegie-Chicago Hubble Program (CCHP) that has produc
ed a calibration of the supernovae Ia using the Tip of the Red Giant Branc
h (TRGB) as a cross-check on Cepheid-based distances. Our first H0 measure
ment was published in [Freedman et al. 2019](https://arxiv.org/abs/1907.05
922)\, with two accompanying papers -- [Hoyt et al. 2019](https://arxiv.or
g/abs/1907.05891) and [Beaton et al. 2019](https://arxiv.org/abs/1908.0612
0) -- that continued to refine systematic and statistical uncertainties af
filiated with the TRGB measurements. Our H0 measurement is in statistical
agreement (Yuan et al. 2019 and [Reid\, Pesce\, and Riess 2019](https://ar
xiv.org/abs/1908.05625)). Originally the CCHP proposed to avoid the Large
Magellanic Cloud\, due to the complexities of measurement therein\, but I
will describe the struggle to use other calibration paths due to systemati
c uncertainties in Gaia DR2 ([Neeley et al. 2019](https://arxiv.org/abs/19
10.01773)). I will counter the concerns raised in Yuan et al. with a discu
ssion of systematics induced from stellar population variance and from nua
nces in photometric measurements that\, when taken into account\, bring ou
r apparently disparate measurements into accord. I conclude with why movin
g into the infrared\, where the impact of dust is reduced\, is the best op
tion\, but list the current instrumentation challenges we face toward real
izing that goal.

ancis Bach\, INRIA\n\nMachine learning algorithms are ubiquitous in most s
cientific\, industrial and personal domains\, with many successful applica

zed by the constant exchanges between theory and practice\, with a stream
of algorithms that exhibit both good empirical performance on real-world p
roblems and some form of theoretical guarantees. Many of the recent and we
ll publicized applications come from deep learning\, where these exchanges
are harder to make\, in part because the objective functions used to trai
n neural networks are not convex. In this talk\, I will present recent res
ults on the global convergence of gradient descent for some specific non-c
onvex optimization problems\, illustrating these difficulties and the asso

DESCRIPTION:Topic: Extreme eigenvalue distributions of sparse random graphs
\n\nSpeaker: Jiaoyang Huang\, Member\, School of Mathematics\n\nVideo: htt
ps://video.ias.edu/analysis/2019/1115-JiaoyangHuang\n\nI will discuss the
extreme eigenvalue distributions of adjacency matrices of sparse random gr
aphs\, in particular the Erd{\H o}s-R{\'e}nyi graphs $G(N\,p)$ and the ran
dom $d$-regular graphs. For Erd{\H o}s-R{\'e}nyi graphs\, there is a cross
over in the behavior of the extreme eigenvalues. When the average degree $
Np$ is much larger than $N^{1/3}$\, the extreme eigenvalues have asymptoti
cally Tracy-Widom fluctuations\, the same as Gaussian orthogonal ensemble.
However\, when $N^{2/9}\ll Np\ll N^{1/3}$ the extreme eigenvalues have as
ymptotically Gaussian fluctuations. The extreme eigenvalues of random $d$-
regular graphs are more rigid\, we prove on the regime $N^{2/9}\ll d\ll N^
{1/3}$ the extremal eigenvalues are concentrated at scale $N^{-2/3}$ and t
heir fluctuations are governed by the Tracy-Widom statistics. Thus\, in th
e same regime of $d$\, $52\%$ of all $d$-regular graphs have the second-la
rgest eigenvalue strictly less than $2\sqrt{d-1}$. These are based on join
t works with Roland Bauerschmidt\, Antti Knowles\, Benjamin Landon and Hor
ng-Tzer Yau.

DESCRIPTION:Topic: The ALMA View of Planet Formation\n\nSpeaker: Jane Huang
\, Harvard University\n\nThe ubiquity and diversity of exoplanets tell us
that planets can emerge under an astonishing range of conditions. Observat
ions of protoplanetary disks yield insights into how the masses\, composit
ions\, and orbital architectures of planets are influenced by their natal
environments. While protoplanets are difficult to detect directly\, the ad
vent of high-resolution\, high-sensitivity telescope facilities such as AL
MA has now made it possible to search systematically for disk structures p
otentially induced by planet-disk interactions and use their morphologies
to infer characteristics of the young planet population. We recently under
took the first high angular resolution ALMA survey of protoplanetary disks
\, the Disk Substructures at High Angular Resolution Program (DSHARP). Con
centric rings and gaps are the most common type of substructure observed i
n dust continuum emission and are found in disks spanning a large range of
ages and stellar host spectral types. The widespread presence of these st
ructures suggests that giant planet formation may occur readily within a m
illion years throughout much of the extent of the disk. Spiral arms are se
en in a minority of disks and may arise either because of perturbations fr
om an unseen wide-orbit companion or from gravitational instabilities. Fin
ally\, while recent planet formation modeling efforts have primarily focus
ed on interpreting dust observations\, I will discuss case studies of how
molecular line observations can uniquely provide key tests of planet forma
tion theories.

DESCRIPTION:Topic: Attractors\, Bifurcations and Curvature in Multi-Field i
nflation\n\nSpeaker: Evangelos Sfakianakis\, Nikhef and Leiden University
\n\nRecent years have seen the introduction of various multi-field inflati
onary scenarios\, in which the curvature and geodesics of the scalar manif
old play a crucial role. I will outline a simple description that unifies
these different proposals and discuss their stability criteria. I will dem
onstrate how the underlying dynamics is governed by an effective potential
\, whose critical points and bifurcations determine the late-time behavior
of the system\, thus unifying hyperinflation\, angular\, orbital and side
-tracked inflation. Interestingly\, hyperinflation can be shown to be a sp
ecial case of side-tracked inflation. This equivalence relies on the enhan
ced isometries of the hyperbolic manifold and I will show the explicit coo
rdinate transformation that maps the two models into each other. In the ca
se of angular inflation\, the universal predictions of multi-field alpha a
ttractors are modified\, allowing us to constrain the curvature of the hyp
erbolic manifold and mass ratio of the two fields\, for certain models.

ute of Science\; Visiting Professor\, School of Mathematics\n\nVideo: http
s://video.ias.edu/HermannWeyl/2019/1118-IritDinur\n\nThe PCP theorem says
that any mathematical proof can be written in a special 'PCP' format such
that it can be verified\, with arbitrarily high probability\, by sampling
only a few symbols in the proof. Hence the name\, Probabilistically Checka
ble Proofs (PCPs). Alternatively and equivalently\, any system of multivar
iate polynomial equations can be efficiently converted into another\, so t
hat if no input satisfies all equations in the former\, no input satisfies
even a tiny fraction of the equations in the later. Moreover\, each of th
e new equations will involve only 3 variables. This theorem is the key to
understanding the difficulty of approximation and optimization problems\;
and also amazingly finds uses in modern cloud computing protocols. We will
explain the context and meaning of the theorem\, and outline a proof that
relies on expander graphs\, which are a central combinatorial object in n
umerous computer science and mathematical areas.

Institute\n\nI will describe my work\, all joint with D. Gaiotto and some
also joint with E. Witten\, to understand the homotopy type of the space o
f (1+1)d N=(0\,1) SQFTs --- what a condensed matter theorist would call 'p
hases' of SQFTs. Our motivating hypothesis (due in large part to Stolz and
Teichner) is that this space models the spectrum called 'topological modu
lar forms'. Our work includes many nontrivial checks of this hypothesis. F
irst\, the hypothesis implies constraints on the possible values of ellipt
ic genera\, and suggests (but does not imply) the existence of holomorphic
SCFTs saturating these constraints\; we have succeeded in constructing su
ch SCFTs in low central charge. Second\, the hypothesis implies the existe
nce of torsion-valued 'secondary invariants' beyond the elliptic genus tha
t protect SQFTs from admitting deformations that spontaneously break super
symmetry. I will explain such an invariant in terms of holomorphic anomali
es and mock modularity.

report on a joint work with M. Abouzaid\, S. Guillermou and T. Kragh. The
nearby Lagrangian conjecture predicts that a closed exact Lagrangian subm
anifold in a cotangent bundle must be Hamiltonian isotopic to the zero-sec
tion. In particular the stable Gauss map of such a Lagrangian should be nu
ll-homotopic. I will explain a proof of the weaker statement that the stab
le Gauss map vanishes on all homotopy groups. The key concept that we intr
oduce is the notion of twisted generating function designed to describe La
grangians with a priori non trivial Gauss map. We also rely on deep result
s of pseudo-isotopy theory due to M. Bökstedt.

DESCRIPTION:Topic: Time-domain & Muli-messenger Astrophysics in the Era of
Big Data\n\nSpeaker: Ashley Villar\, Harvard-Smithsonian Center for Astrop
hysics\n\nThe Large Synoptic Survey Telescope (LSST) will begin science op
erations in 2022 and is expected to increase the discovery rate of extraga
lactic transients by two orders of magnitude. With this transition comes t
he important question: how do we classify these events and separate the in
teresting “needles” from the “haystack” of objects? While it’s necessary t
o pick out these needles\, it is equally important to understand the hayst
ack — or the millions of events which lack any multi wavelength or spectro
scopic followup. In this talk\, I will discuss ongoing efforts to classify
/characterize the future haystack and to understand one particularly excit
ing type of needle: kilonovae. In particular\, I will introduce two method
s to classify supernovae based on their optical light curves\, which have
been trained and tested on data from the Pan-STARRS Medium Deep Survey. Th
e first method combines Bayesian model fitting with a variety of supervise
d classification methods\, while the second method uses a semi-supervised
recurrent neural network-based autoencoder. I will then discuss how well w
e can extract physical insights from LSST-like light curves without additi
onal followup. I will focus on the rare classes of Type I superluminous su
pernovae and kilonovae as case studies. I will show how target-of-opportun
ity observations will make LSST an ideal instrument for kilonova discovery
.

DESCRIPTION:Topic: The Black Hole-jet Connection in M87: Linking simulation
s to VLBI images\n\nSpeaker: Andrew Chael\, Princeton Center for Theoretic
al Physics (PCTS)\n\nThe Event Horizon Telescope (EHT) has produced the fi
rst image of the 1.3 mm-wavelength emission around the black hole 'shadow'
at the heart of M87. The hot plasma in the accretion flow around M87's ce
ntral black hole illuminates the spacetime\, and the flow's magnetic field
extracts energy from the black hole to launch the famous relativistic jet
which is prominent in VLBI images at longer wavelengths. General relativi
stic magnetohydrodynamic (GRMHD) simulations are a powerful tool for study
ing the accretion flow and jet in M87. I will discuss the library of these
simulations used by the EHT collaboration to constrain the properties of
the black hole and emitting plasma in M87. I will also describe new simula
tions of M87 which go beyond single-fluid MHD to evolve separate electron
and ion populations\, as these species are likely not in equilibrium in ho
t accretion flows. These simulations can connect EHT images of the shadow
at 1.3 mm to the relativistic jet at longer wavelengths to constrain the p
hysics of the jet launching region\, and indicate the powerful\, wide-open
ing-angle jet in M87 is naturally launched by a magnetically arrested accr
etion flow.Should you wish to order lunch\, you may do so here https://for

s via HDXs\n\nSpeaker: Prahladh Harsha\, Tata Institute of Fundamental Res
earch\n\nVideo: https://video.ias.edu/csdm/2019/1125-PrahladhHarsha\n\nIn
this talk\, I'll illustrate how to lift a 'small' locally testable code vi
a a high dimensional expander (HDX) to a 'large' locally testable code. Gi
ven a D-left regular bipartite graph G = ([n]\, [m]\, E) and a 'small' cod
e C \in {0\,1}^D\, the Tanner construction shows how to lift this code to
a 'large' code on n- bits. These Tanner lifts are extremely useful. For in
stance\, if C is a 'small' code with good distance and rate and G is a bip
artite expander\, then the Sipser-Spielman analysis shows that the lifted
code is a 'large' code that has good distance and rate. We will show a sim
ilar lifting property for local-testability. More precisely\, let C_0 be a
small code such that its lift C (defined via a bipartite graph) has non-t
rivial rate. We will show that if the bipartite-graph is part of a HDX and
a small-lift is testable\, then so is the large-lift C.

r: Sanjoy Dasgupta\, University of California\, San Diego\; Member\, Schoo
l of Mathematics\n\nVideo: https://video.ias.edu/members/2019/1125-SanjoyD
asgupta\n\nThe 'nearest neighbor (NN) classifier' labels a new data instan
ce by taking a majority vote over the k most similar instances seen in the
past. With an appropriate setting of k\, it is capable of modeling arbitr
ary decision rules. Traditional convergence analysis for nearest neighbor\
, as well as other nonparametric estimators\, has focused on two questions
: (1) universal consistency---that is\, convergence (as the number of data
points goes to infinity) to the best-possible classifier without any cond
itions on the data-generating distribution---and (2) rates of convergence
that are minimax-optimal\, assuming that data distribution lies within som
e standard class of smooth functions. We advance what is known on both the
se fronts. But we also show how to attain significantly stronger types of
results: (3) rates of convergence that are accurate for the specific data
distribution\, rather than being generic for a smoothness class\, and (4)
rates that are accurate for the distribution as well as the specific query
point. Along the way\, we introduce a notion of 'margin' for nearest neig
hbor classification. This is a function m(x) that assigns a positive real
number to every point in the input space\; and the size of the data set ne
eded for NN (with adaptive choice of k) to predict correctly at x is\, rou
ghly\, 1/m(x). The statistical background needed for understanding these r
esults is minimal\, and will be introduced during the talk. This is joint
work with Akshay Balsubramani\, Kamalika Chaudhuri\, Yoav Freund\, and Sha
y Moran.

DESCRIPTION:Topic: Perspectives on the Generally-Relativistic Two-Body Prob
lem from Double Copy & EFT\n\nSpeaker: Radu Roiban\, Pennsylvania State Un
iversity\n\nWhile the flat space two-body problem is integrable\, the gene
rally-relativistic one is not starting at the next-to-leading order.\nIn t
he appropriate classical limit\, scattering amplitude-based techniques can
yield the classical interaction of massive bodies to all orders in their
velocities and to fixed order in the expansion in Newton's constant\, that
is a fixed order in the post-Minkowskian (relativistic weak-field) expans
ion.\nIn this talk we review an amplitudes-based framework for such calcul
ations and the derivation of the third order in the post-Minkowskian expan
sion for the conservative Hamiltonian of a compact spinless binary system.
We also describe the scattering angle at this order as well as a first co
mparison with numerical GR.

\nSpeaker: Abigail Ward\, Harvard University\n\nWe show evidence that homo
logical mirror symmetry is a phenomenon that exists beyond the world of Kä
hler manifolds by exhibiting HMS-type results for a family of complex surf
aces which includes the classical Hopf surface (S^1 x S^3). Each surface S
we consider can be obtained by performing logarithmic transformations to
the product of P^1 with an elliptic curve. We use this fact to associate t
o each S a mirror 'non-algebraic Landau-Ginzburg model' and an associated
Fukaya category\, and then relate this Fukaya category and the derived cat

DESCRIPTION:Topic: How Do You Solve a Problem like (Photometric) Supernovae
?\n\nSpeaker: Renée Hlozek\, University of Toronto\n\nVideo: https://video
.ias.edu/puias/2019/1126-Ren%C3%A9eHlozek\n\nThe Large Synoptic Survey Tel
escope will generate a data deluge: millions of transients and variable so
urces will need to be classified from their light curves. Photometric LSST
Astronomical Time-series Classification Challenge (PLAsTiCC) brings a wid
e range of models together\, simulated under LSST-like conditions for the
first time. PLAsTiCC was delivered to the community through a Kaggle chall
enge\, designed to stimulate interest in time-series photometric classific
ation and deliver methodologies that will advance the LSST science case. I
will give an overview of the road to PLAsTiCC\, the models and the valida
tion of the data\, discuss some of its science results. I'll present new r
esults on early classification of transients using active learning to prio
ritize spectroscopic resources\, and discuss advances in the end goal: ful
ly photometric supernova cosmology.

DESCRIPTION:Topic: Rainbow fractional matchings\n\nSpeaker: Ron Holzman\, T
echnion\n\nVideo: https://video.ias.edu/csdm/2019/1202-RonHolzman\n\nGiven
a family of m matchings in a graph G (where each matching can be thought
of as a color class)\, a rainbow matching is a choice of edges of distinct
colors that forms a matching. How many matchings of size n are needed to
guarantee the existence of a rainbow matching of size n? If G is bipartite
\, a theorem of Drisko generalized by Aharoni and Berger says that m = 2n
- 1 suffices (and is best possible). In a general graph G\, this is not th
e case\, but m = 2n is conjectured to be enough. We prove a fractional ver
sion of this conjecture\, not only for graphs but also for r-uniform hyper
graphs. The main tool is a topological result of Kalai and Meshulam. This
is joint work with Ron Aharoni and Zilin Jiang.

mathematical models describing how information is maintained and recalled
in these experiments. Surprisingly\, they provide a very good description
of experimental data obtained with internet-based memory experiments on l
arge number of human subjects. Moreover\, more detailed mathematical analy

uctures in the sense of Kontsevich-Vlassopoulos. For a Weinstein manifold\
, an exact Calabi-Yau structure on the wrapped Fukaya category induces a c
lass in the degree one equivariant symplectic cohomology\, which we call a
cyclic dilation. We prove that for many Weinstein manifolds with cyclic d
ilations\, there is an upper bound on the number of pairwise disjoint Lagr
angian spheres\, and the homology classes of these Lagrangian spheres are
non-trivial. On the other hand\, we show that the Milnor fiber of a 3-fold
triple point admits a cyclic dilation despite that there is no quasi-dila
tion.

DESCRIPTION:Topic: Dynamics of Black Holes and Gravitational Waves\n\nSpeak
er: Hyung Mok Lee\, KASI (Korea)\n\nThe advanced detectors of gravitationa
l waves detected several black hole binary mergers one neutron star merger
. Such binaries are either formed by evolution of massive binary systems o
r through dynamical processes in dense stellar systems. I will focus on th
e dynamical scenarios originating from globular clusters. The galactic nuc
lei star clusters (NC) could also provide suitable environment for the dyn
amical binary formation\, but they are likely to be much less efficient th
an globular clusters. In globular clusters\, the black holes become the mo
st massive components within 10 million years after the birth of the clust
ers. The black holes experience dynamical friction that causes central con
centration of massive black hoes in the central parts of the clusters in a
short time scale. Black hole binaries can be formed either direct capture
or by three-body processes in dense core. Under typical conditions of glo
bular clusters\, three-body processes are much more efficient than direct
capture. The binaries experience subsequent interactions with surrounding
stars (mostly black holes) and the orbit shrinks due to such interactions.
Eventually the binaries get ejected along with surrounding black holes\,
leading to nearly complete desertification of black holes in the cluster i
n a few billion years. The ejected binaries undergo passive evolution outs
ide the cluster through gravitational radiation. Some fraction of the them
will merge within Hubble time. We expect the mass ratios of two black hol
es in binaries would be close to unity. Also the spin directions are expec
ted to be randomly oriented relative to the orbital angular momentum vecto
r. iBinaries composed of a black hole and a neutron star will be very rare
among dynamical binaries. I will also describe the gravitational waves ar
ising from the hyperbolic or parabolic encounters between black holes and
detectability of such events.

DESCRIPTION:Topic: A distributional code for value in dopamine-based reinfo
rcement learning\n\nSpeaker: Matthew Botvinick\, DeepMind\n\nTwenty years
ago\, a link was discovered between the neurotransmitter dopamine and the
computational framework of reinforcement learning. Since then\, it has bec
ome well established that dopamine release reflects a reward prediction er
ror\, a surprise signal that drives learning of reward predictions and sha
pes future behavior. According to the now canonical theory\, reward predic
tions are represented as a single scalar quantity\, which supports learnin
g about the expectation\, or mean\, of stochastic outcomes. I'll present r
ecent work in which we have proposed a novel account of dopamine-based rei
nforcement learning\, and adduced experimental results which point to a si
gnificant modification of the standard reward prediction error theory. Ins
pired by recent artificial intelligence research on distributional reinfor
cement learning\, we hypothesized that the brain represents possible futur
e rewards not as a single mean\, but instead as a probability distribution
\, effectively representing multiple future outcomes simultaneously and in
parallel. This idea leads immediately to a set of empirical predictions\,
which we tested using single-unit recordings from mouse ventral tegmental
area. Our findings provide strong evidence for a neural realization of di
stributional reinforcement learning.

DESCRIPTION:Topic: A CMB Millikan Experiment with Axion Strings\n\nSpeaker:
Prateek Agrawal\, Harvard University\n\nVery light axions are a generic p
rediction of string compactifications. If cosmic strings associated with t
hese axions were produced in the early universe\, they quickly approach a
so-called scaling solution\, such that strings persist in the sky today. I
will present some remarkable signals of such strings coupled to photons.
In this string background\, there is a model-independent polarization rota
tion of CMB photons equal to $\alpha_{em}$ up to a rational number. This m
anifests itself as a rotation of E-modes in the CMB polarization to B-mode
s. The current CMB experimental sensitivity to this rotation is about 1%\,
with many orders of magnitude improvement expected for future experiments
. I will show how measuring the undetermined rational number may shed ligh
t on the quantization of electric charge in the standard model. These stri
ngs may also be visible in strongly lensed quasar systems.

DESCRIPTION:Topic: Thin groups and the arithmetic of imaginary quadratic fi
elds\n\nSpeaker: Katherine Stange\, University of Colorado\, Boulder\n\nTh
e Farey subdivision of the real line describes the action of PSL(2\,Z) and
gives a continued fraction algorithm approximating real numbers by ration
al numbers. Asmus Schmidt defined an analogue for the complex plane\, depe
nding on a choice of Euclidean imaginary quadratic field. I generalize his
construction to arbitrary imaginary quadratic fields\, which gives rise t
o an arrangement of circles into orbits of the Bianchi group PSL(2\,O_K).
Geometric aspects of this picture relate to arithmetic properties of the f
ield. Furthermore\, Apollonian circle packings arise naturally from the Ga
ussian case. The curvatures of integral Apollonian circle packings conject
urally satisfy a local-global property for which a density-one statement w
as proven by Bourgain and Kontorovich. Inspired by the viewpoint of Schmid
t arrangements\, we can define an infinite family of integral circle packi
ngs for which the methods of Bourgain-Kontorovich generalize (joint work w
ith Elena Fuchs and Xin Zhang). Daniel Martin has recently generalized the
se pictures to provide a continued fraction algorithm for non-Euclidean im
aginary quadratic fields.

DESCRIPTION:Topic: Entropy Rain and the Solar Convective Conundrum: Dilutio
n and Compression of Individual Convective Downflows\n\nSpeaker: Evan Ande
rs\, University of Colorado\, Boulder\n\nLarge-scale convective flows call
ed giant cells were once thought to transport the Sun’s luminosity in the
solar convection zone\, but recent observations do not detect giant cells.
The absence of giant cells is referred to as the “Solar Convective Conund
rum” and calls into question our fundamental understanding of stellar enve
lope convection. In place of large-scale flows\, some authors have suggest
ed the solar luminosity may instead be transported by small droplets of ra
pidly falling\, low entropy fluid. This “entropy rain” could propagate as
dense vortex rings\, analogous to rising buoyant “thermals” in the Earth’s
atmosphere. In this work\, we model stellar downflows as dense\, negative
ly buoyant thermals and develop an analytical theory describing their evol
ution. We verify the theory with 2D cylindrical and 3D cartesian simulatio
ns of laminar\, axisymmetric thermals in highly stratified atmospheres. Ou
r results show that dense thermals fall in two categories: a stalling regi
me in which the droplets slow down and expand\, and a falling regime in wh
ich the droplets accelerate and shrink as they propagate downwards. We est
imate that solar downflows are in the falling regime and maintain their en
tropy perturbation against diffusion until they reach the base of the conv
ection zone. This suggests that entropy rain may be an effective nonlocal
mechanism for transporting the solar luminosity.

d' version of this problem\, where one observes only the unordered sets $\
{x_1\,…\,x_n\}$ and $\{y_1\,…\,y_n\}$ and still hopes to recover informati

DESCRIPTION:Topic: Episodic memory from first principles\n\nSpeaker: Michel
angelo Naim\, Weizmann Institute of Science\; Visitor\, School of Natural
Sciences\n\nTo understand human memory one needs to understand both the ab
ility to acquire vast amounts of information and at the same time the limi
ted ability to recall random material. We have recently proposed a model f
or recalling random unstructured information that gives an analytical pred
iction for the number of words that can be recalled. It is also known that
structured information is easier to remember and recall than random one.
In real life\, information exhibits multi-level hierarchical organization.
How these models can help us understand the real meaning of language?

DESCRIPTION:Topic: Studying the Magnetic Field of the Diffuse ISM in 3D\n\n
Speaker: Gina Panopoulou\, California Institute of Technology\n\nThe abili
ty to reconstruct the 3D magnetic field in the Galactic interstellar mediu
m (ISM) is instrumental for many different scientific efforts. A 3D magnet
ic field reconstruction can inform us about the dynamics in star forming r
egions\, the origin of ultra-high energy cosmic rays\, as well as large-sc
ale Galactic processes. Such 3D maps are also necessary for accurately mod
eling polarized dust emission\, which acts as a dominant foreground contam
inating the polarization of the Cosmic Microwave Background. While modelin
g the magnetic field in 3D using 2D data has been possible in the past\, t
he advent of Gaia allows for actually measuring the field in three-dimensi
ons with unprecedented accuracy. I will present an effort towards this goa
l: tomographic mapping of the magnetic field morphology using dust-induced
starlight polarization. By combining information from a diverse set of ob
servables\, I will demonstrate what we can learn about the magnetized ISM
from such an endeavor.

Wolfson\, University of California\, Irvine\n\nVideo: https://video.ias.e
du/special/2019/1205-JesseWolfson\n\nGiven a polynomial in one variable\,
what is the simplest formula for the roots in terms of the coefficients? H
ilbert conjectured that for polynomials of degree 6\,7 and 8\, any formula
must involve functions of at least 2\, 3 and 4 variables respectively (su
ch formulas were first constructed by Hamilton). In a little-known paper\,
Hilbert sketched how the 27 lines on a cubic surface should give a 4-vari
able solution of the general degree 9 polynomial. In this talk I’ll recall
Klein and Hilbert's geometric reformulation of solving polynomials\, expl
ain the gaps in Hilbert's sketch and how we can fill these using modern me
thods. As a result\, we obtain best-to-date upper bounds on the number of
variables needed to solve a general degree n polynomial for all n\, improv
ing results of Segre and Brauer.

that Galactic foregrounds such as dust can easily mimic inflationary sign
als. Though typically foregrounds are separated from primordial signals us
ing the foregrounds' different frequency dependence\, in this talk I’ll di

t levels corresponding to r~0.001 at 2 sigma for CMB-S4 noise levels. I’ll
also outline how anisotropy statistics can be used to construct an estima

DESCRIPTION:Topic: Constraining Neutrino Mass with the Bispectrum\n\nSpeake
r: ChangHoon Hahn\, Lawrence Berkeley National Laboratory\n\nMassive neutr
inos suppress the growth of structure below their free-streaming scale and
leave an imprint on large-scale structure. Measuring this imprint allows
us to constrain the sum of neutrino masses\, Mnu\, a key parameter in part
icle physics beyond the Standard Model. However\, degeneracies among cosmo
logical parameters\, especially between Mnu and sigma8\, limit the constra
ining power of standard two-point clustering statistics. I will present wh
ether we can break these degeneracies and constrain Mnu with the next high
er-order correlation function — the bispectrum. I first examine the redshi
ft-space halo bispectrum of 800 N-body simulations from the HADES suite an
d demonstrate that the bispectrum helps break the Mnu-sigma8 degeneracy. T
hen I will present the full information content of the redshift-space halo
bispectrum down to nonlinear scales using a Fisher matrix forecast of {Om
\, Ob\, h\, ns\, sigma8\, Mnu} with 22\,000 N-body simulations of the Quij
ote suite. For kmax=0.5 h/Mpc\, the bispectrum provides Om\, Ob\, h\, ns\,
and sigma8 constraints 1.9\, 2.6\, 3.1\, 3.6\, and 2.6 times tighter than
the power spectrum. For Mnu\, the bispectrum improves the 1sigma constrai
nt from 0.2968 to 0.0572 eV — over 5 times tighter than the power spectrum
. Lastly\, I will present ongoing projects that are laying down the framew
ork for a full bispectrum analysis of DESI: including a comprehensive bias
(HOD) model\, data compression for the bispectrum\, paired-fixed simulati
ons for the bispectrum\, and efficient simulation-based inference methods.

DESCRIPTION:Topic: The h-principle in symplectic geometry\n\nSpeaker: Emmy
Murphy\, Northwestern University\; von Neumann Fellow\, School of Mathemat
ics\n\nVideo: https://video.ias.edu/members/2019/1209-EmmyMurphy\n\nSymple
ctic geometry\, and its close relative contact geometry\, are geometries c
losely tied to complex geometry\, smooth topology\, and mathematical physi
cs. The h-principle is a general method used for construction of smooth ge
ometric objects satisfying various underdetermined properties. In the symp
lectic context\, h-principles typically give constructions of surprising e
xotica\, and methods for detecting the basic flexible objects. We survey a
number of results from the previous decade.

topology\n\nSpeaker: Ko Honda\, University of California\, Los Angeles\n
\nConvex surface theory and bypasses are extremely powerful tools for anal
yzing contact 3-manifolds. In particular they have been successfully appli
ed to many classification problems. After briefly reviewing convex surface
theory in dimension three\, we explain how to generalize many of their pr
operties to higher dimensions. This is joint work with Yang Huang.

DESCRIPTION:Topic: On the gradient-flow structure of multiphase mean curvat
ure flow\n\nSpeaker: Tim Laux\, University of California\, Berkeley\n\nVid
eo: https://video.ias.edu/analysis/2019/1209-TimLaux\n\nDue to its importa
nce in materials science where it models the slow relaxation of grain boun
daries\, multiphase mean curvature flow has received a lot of attention ov
er the last decades.\n\nIn this talk\, I want to present two theorems. The
first one is a convergence result for the vector-valued Allen-Cahn equati
on. Similar to an intriguing proof by Luckhaus-Sturzenhecker and a recent
work with Felix Otto\, we derive the convergence of the phase field to a d
istributional solution of multiphase mean curvature flow. The second resul
t is a weak-strong uniqueness principle: as long as a strong solution to m
ultiphase mean curvature flow exists\, any distributional solution with op
timal energy dissipation rate has to coincide with this solution.\n\nBoth
proofs are based on the gradient-flow structure of multiphase mean curvatu
re flow. In particular\, for the first result\, we construct a phase-field
version of the tilt-excess\, a well-known functional in geometric measure
theory. For the second result\, we define a suitable relative entropy fun
ctional\, which in this geometric context may be viewed as a time-dependen
t variant of calibrations. Just like the existence of a calibration guaran
tees that one has found a global minimum\, the existence of a time-depende
nt calibration ensures that the route of steepest descent in the energy la
ndscape is unique and stable.\n\nThis is joint work with Julian Fischer\,
Sebastian Hensel\, and Thilo Simon.

DESCRIPTION:Topic: Graph removal lemmas\n\nSpeaker: Fan Wei\, Member\, Scho
ol of Mathematics\n\nContinuing last week's lecture\, among the numerous a
pplications of the regularity lemma\, a classical one is the graph removal
lemma. It has applications in fields such as number theory and theoretica
l computer science. For every fixed graph H\, the H-removal lemma gives a
highly nontrivial equivalence between the density of H in G and the L1 dis
tance between a graph G to the set of H-free graphs. The quantitative esti
mates remains a big open question in graph theory. In this talk\, I will c
over the standard proof of the graph removal lemma\, and discuss some rece
nt works on a strengthening of the usual graph removal lemma.

DESCRIPTION:Topic: Gamma-ray Observations of M31 and Dark Matter Implicatio
ns\n\nSpeaker: Simona Murgia\, University of California\, Irvine\n\nThe An
dromeda galaxy is the closest spiral galaxy to us. It harbors a massive da
rk matter halo which may span up to ∼600 kpc across and comprises ∼90% of
the galaxy’s total mass. This halo size translates into a large diameter o
f 42 degrees on the sky for an M31–Milky Way distance of 785 kpc\, but its
presumably low surface brightness makes it challenging to detect with gam
ma-ray telescopes. Using data from the Fermi Large Area Telescope\, we mak
e a detailed study of the gamma-ray emission between 1-100 GeV towards And
romeda's outer halo\, and perform an in-depth analysis of the systematic u
ncertainties related to the observations. In this talk\, I will discuss th
ese results and implications for dark matter.

DESCRIPTION:Romanian director Cristian Mungiu crafted a complex story of co
rruption and loyalty with his award-winning Graduation (original title: Ba
calaureat). The film follows the brilliant daughter of a successful physic
ian as she prepares for college. She has won a scholarship to Cambridge Un
iversity\, on the condition that she receives top grades in her final exam
s. A dramatic incident the day before the latter destabilizes her and jeop
ardizes her chances. Her distressed father is offered by a police official
a deal to fix the exams’ results. The film subtly explores the meandering
s of corruption in the former Socialist country. In The Guardian\, Peter B
radshaw writes\, “Graduation is an intricate\, deeply intelligent film\, a
nd a bleak picture of a state of national depression in Romania\, where th
e 90s generation hoped they would have a chance to start again.” The film
won the 2016 Cannes Film Festival award for Best Director\, and the 2016 C
hicago International Film Festival award for Best Actor went to Adrian Tit
ieni.\n\nThis film runs 2 hours and 8 minutes.\n\nA post-screening discuss
ion will be led by Virág Molnár\, Associate Professor of Sociology at The
New School\, and Naor Ben-Yehoyada\, Assistant Professor in the Department
of Anthropology at Columbia University\, both current Members in the Scho
ol of Social Science.\n\nThis is the third film in the series Economy and
Society\, curated by the School of Social Science.

DESCRIPTION:Topic: Probing Microphysics of the Hot Intracluster Medium\n\nS
peaker: Irina Zhuravleva\, University of Chicago\n\nGalaxy clusters are th
e largest dark matter-dominated objects in the Universe with the most mass
ive baryonic component in the form of hot\, X-ray-emitting plasma. Due to
their size and relative simplicity\, clusters are unique laboratories for
probing plasma properties on microscales\, such as turbulence\, viscosity\
, heat conduction\, magnetic fields. These properties remain largely unmea
sured and their theoretical predictions vary by orders of magnitude. In my
talk\, I will discuss how statistical properties of gas perturbations imp
rinted in the high-resolution X-ray images of galaxy clusters are used to
probe gas turbulence\, the effective equation of state of small-scale pert
urbations and plasma behavior on spatial scales comparable to Coulomb mean
free path. The latter allows us to probe transport processes\, in particu
lar\, gas viscosity in the bulk intergalactic plasma. At the end of my tal
k\, I will briefly discuss how we will measure the statistical properties
of the gas velocity field with the near-future XRISM mission.

DESCRIPTION:Topic: Measurements of CMB Polarization with the Polarization M
odulation Technique\n\nSpeaker: Satoru Takakura\, Kavli Institute for the
Physics and Mathematics of the Universe\n\nAs our last journal club for th
e fall semester Satoru Takakura (IPMU) will deliver his Dicke talk. Abstra
ct: Polarization anisotropies on the cosmic microwave background (CMB) is
an interesting target for astroparticle physics. Especially\, the parity-o
dd component\, the so-called B-mode\, in degree scale is a unique probe of
primordial gravitational waves from the cosmic inflation. The POLARBEAR e
xperiment is a ground-based CMB polarization measurement at the Atacama De
sert in Chile with 1\,274 transition-edge-sensor (TES) bolometers sensitiv
e to the 150 GHz band on a 2.5 m aperture telescope. One of the challenges
for the degree-scale measurement is the mitigation of the low-frequency n
oise\, the so-called 1/f noise. Since 2014\, POLARBEAR has employed a pola
rization modulation technique using a continuously rotating half-wave plat
e. The same technique is used in the Atacama B-mode Search (ABS) experimen
t at Princeton and the small aperture telescopes in the Simons Observatory
(SO) experiment. In POLARBEAR\, however\, we find that there are remainin
g 1/f noises due to instrumental leakages and polarized clouds. I am inter
ested in improving the characterization of the 1/f noise using the ABS dat
a and also developing a new cloud monitor\, which will contribute to SO to
measure inflationary B-modes. Should you wish to order lunch\, you may do
so by 10am on Thursday here:

s on the torus\, anyons\, and fractons. There is\, however\, hope to fully
understand short-range entangled\, or 'invertible' systems\, which do not
have the aforementioned features but may possess gapless edge modes. In t
he case of non-interacting fermions\, the topological classification is ba
sed on K-theory. I will argue that general invertible systems are describe
d by some homotopy spectrum (or equivalently\, generalized cohomology theo
ry). However\, the exact answer is not yet known.

peaker: Keith Frankston\, Rutgers University\n\nVideo: https://video.ias.e
du/csdm/2019/1216-KeithFrankston\n\nGiven an increasing family F in {0\,1}
^n\, its measure according to mu_p increases and often exhibits a threshol
d behavior\, growing quickly as p increases from near 0 to near 1 around a
specific value p_c. Thresholds of families have been of great historical
interest and a central focus of the study of random discrete structures (e
.g. random graphs and hypergraphs)\, with estimation of thresholds for spe
cific properties the subject of some of the most challenging work in the a
rea. In 2006\, Kahn and Kalai conjectured that a natural (and often easy t
o calculate) lower bound q(F) (which we refer to as the “expectation-thres
hold”) for the threshold is in fact never far from its actual value. We pr
ove a fractional version (proposed by Talagrand) of this so called “expect
ation-threshold” conjecture showing that for any increasing family we have
p_c(F) = O(q_f(F) log \ell(F))\, where q_f is the “fractional expectation
-threshold” and \ell(F) is the maximum size of a minimal element of F. Thi
s result easily implies several previously difficult results in probabilis
tic combinatorics such as thresholds for perfect hypergraph matchings (Joh
ansson–Kahn–Vu) and bounded-degree spanning trees (Montgomery). Our approa
ch builds on a recent breakthrough of Alweiss\, Lovett\, Wu and Zhang on t
he Erdős–Rado “Sunflower Conjecture.” This is joint work with Jeff Kahn\,
Bhargav Narayanan\, and Jinyoung Park.

DESCRIPTION:Topic: New Statistical Descriptions for Non-Gaussian Cosmology
\n\nSpeaker: Erwan Allys\, École Normale Supérieure\n\nOne of the current
difficulties while working with cosmological observations in non-linear re
gimes is to be able to efficiently characterize their non-Gaussian feature
s. It is for example the case while studying the late time LSS. In this ta
lk\, I will present new statistical descriptions of non-Gaussian fields\,
which have been developed in data-sciences\, and explain how such descript
ions can efficiently characterize the coupling between different scales. I
n will them show different applications of these statistics on several cos
mological problems. Organizers are Jo Dunkley\, Princeton University\, and
Matias Zaldarriaga\, Institute for Advanced Study. This week's meeting is
at the Institute for Advanced Study. Attendees can bring lunch or purchas
e it in the IAS Dining Hall.

DESCRIPTION:Topic: Permutation property testing\n\nSpeaker: Fan Wei\, Membe
r\, School of Mathematics\n\nVideo: https://video.ias.edu/csdm/2019/1217-F
anWei\n\nThe importance of analyzing big data and in particular very large
networks has shown that the traditional notion of a fast algorithm\, one
that runs in polynomial time\, is often insufficient. This is where proper
ty testing comes in\, whose goal is to very quickly distinguish between ob
jects that satisfy a certain property from those that are ε-far from satis
fying that property. It turns out to be closely related to major developme
nts in combinatorics\, number theory\, discrete geometry\, and theoretical
computer science. Some of the most general results in this area give 'con
stant query complexity' algorithms\, which means the amount of information
it looks at is independent of the input size. These results are proved us
ing regularity lemmas or graph limits. Unfortunately\, typically the proof
s come with no explicit bound for the query complexity\, or enormous bound
s\, of tower-type or worse\, as a function of 1/ε\, making them impractica
l. We show by entirely new methods that for permutations\, such general re
sults still hold with query complexity only polynomial in 1/ε. We also pro
ve stronger results for graphs through the study of new metrics.

an Arora\, Johns Hopkins University\; Member\, School of Mathematics\n\nVi
deo: https://video.ias.edu/machinelearning/2019/1218-RamanArora\n\nOnline
learning is a popular framework for sequential prediction problems. The st
andard approach to analyzing an algorithm's (learner's) performance in onl
ine learning is in terms of its empirical regret defined to be the excess
loss suffered by the online learner compared to the best algorithm in hind
sight. Regret makes sense when the learner's environment is oblivious\; ho
wever\, there is a serious difficulty in interpreting regret when the envi
ronment is reactive. The problem stems from the fact that regret evaluates
any competing strategy on the same sequence of losses as generated in res
ponse to the learner's actions. This does not make much sense in reactive
environments such as financial markets\, healthcare\, and social networks\
, where learner's actions affect potential future outcomes. To deal with t
his issue\, we introduced policy regret\, a counterfactual notion of regre
t designed to capture the reactive nature of the learning environment. In
this talk\, we will revisit policy regret in a partial observation setting
given in terms of a feedback graph\, and a game-theoretic setting where t
he environment is a self-interested agent rather than a malicious adversar
y.

DESCRIPTION:Topic: Weak solutions to the Navier--Stokes inequality with arb
itrary energy profiles\n\nSpeaker: Wojciech Ożański \, University of South
ern California\; Member\, School of Mathematics\n\nIn the talk we will foc
us on certain constructions of weak solutions to the Navier--Stokes inequa
lity (NSI)\, \[ u \cdot \left( u_t - \nu \Delta + (u\cdot \nabla ) u+ \nab
la p \right) \leq 0\] on $\mathbb R^3$. Such vector fields satisfy both th
e strong energy inequality and the local energy inequality (but not necess
arily solve the Navier--Stokes equations). Given $T>0$ and a nonincreasing
energy profile $e : [0\,T] \to [0\,\infty )$ we will construct a weak sol
ution to the NSI that is localised in space and whose energy profile $\| u
(t)\|_{L^2 (\mathbb R^3 )}$ stays arbitrarily close to $e(t)$ for all $t\i
n [0\,T]$.\nThe relevance of such solutions is that\, despite not satisfyi
ng the Navier--Stokes equations\, they do satisfy the partial regularity t
heory of Caffarelli\, Kohn & Nirenberg (Comm. Pure Appl. Math.\, 1982). In
fact\, Scheffer's constructions of weak solutions to the Navier--Stokes i
nequality (Comm. Math. Phys.\, 1985 & 1987) admit a finite-time blow-up on
a Cantor set\, which shows that the Caffarelli\, Kohn & Nirenberg theory
is sharp for such solutions. We will discuss the main ideas of his constru
ctions\, as well as present a stronger result: a construction of weak solu
tions to the NSI which follow a prescribed energy profile at the times lea
ding to the blow-up on the Cantor set.

DESCRIPTION:Topic: Compositional inductive biases in human function learnin
g\n\nSpeaker: Samuel J. Gershman\, Harvard University\n\nThis talk present
s evidence that humans learn complex functions by harnessing compositional
ity: complex structure is decomposed into simpler building blocks. I forma
lize this idea in the framework of Bayesian nonparametric regression using
a grammar over Gaussian process kernels\, and compare this approach with
other structure learning approaches. People consistently chose composition
al (over non-compositional) extrapolations and interpolations of functions
. Experiments designed to elicit priors over functional patterns revealed
an inductive bias for compositional structure. Compositional functions are
perceived as subjectively more predictable than noncompositional function
s\, and exhibited other signatures of predictability\, such as enhanced me
morability. Taken together\, these results support the view that the human
intuitive theory of functions is inherently compositional.

DESCRIPTION:Topic: Foundations of Intelligent Systems with (Deep) Function
Approximators\n\nSpeaker: Simon Du\, Member\, School of Mathematics\n\nFun
ction approximators\, like deep neural networks\, play a crucial role in b
uilding machine-learning based intelligent systems. This talk covers three
core problems of function approximators: understanding function approxima
tors\, designing new function approximators\, and applying function approx
imators.In the first part of the talk\, I will talk about understanding de
ep neural networks. I will show that the over-parameterized neural network
is equivalent to a new type of kernel\, Neural Tangent Kernel. Using this
equivalence\, we show that gradient descent provably finds the global opt
imum when optimizing an over-parameterized neural network\, and the learne
d neural network also generalizes well. In the second part of the talk\, I
will focus on designing new function approximators with strong empirical
performance. We transform (fully-connected\, graph\, convolutional) neural
networks to (fully-connected\, graph\, convolutional) Neural Tangent Kern
els which achieve superior performance on standard benchmarks. In the last
part of the talk\, I will focus on applying function approximation in the
reinforcement learning setting. I will give an exponential sample complex
ity lower bound of using function approximation to model the optimal polic
y. Then I will discuss what additional structures that admit statistically
efficient algorithms.

DESCRIPTION:Topic: Inverse problems for quantum graphs\n\nSpeaker: Pavel Ku
rasov\, Stockholm University\n\nTo solve the inverse spectral problem for
the Schrödinger equation on a metric graph one needs to determine:\n• the
metric graph\;\n• the potential in the Schrödinger equation\;\n• the verte
x conditions (connecting the edges together).\nThe inverse problem is solv
ed completely in the case of trees under mild restrictions on the vertex c
onditions. The main tool is a combination of the boundary control and M-fu
nction approaches to inverse problems. These two approaches are essentiall
y equivalent in the case of single interval\, but their different features
may be effectively exploited to solve different partial inverse problems
for trees. The bunch cutting procedure allows one to reduce the tree step-
by-step by removing edges and vertices close to the boundary.\nTo solve th
e inverse problem for graphs with cycles we propose to use magnetic bounda
ry control and magnetic M-functions where spectral data for a fixed potent
ial are considered as functions of the magnetic fluxes through graph cycle
s. To solve the inverse problem we use cycle opening procedure mapping spe
ctral data for arbitrary graphs with cycles to spectral data for trees on
the same edge set. The graph and potential are reconstructed assuming so f
ar standard vertex conditions.

DESCRIPTION:Topic: The Blessings of Multiple Causes\n\nSpeaker: David M. Bl
ei\, Columbia University\n\nCausal inference from observational data is a
vital problem\, but it\ncomes with strong assumptions. Most methods requir
e that we observe\nall confounders\, variables that affect both the causal
variables and\nthe outcome variables. But whether we have observed all co
nfounders is\na famously untestable assumption. We describe the deconfound
er\, a way\nto do causal inference with weaker assumptions than the classi
cal\nmethods require.\n\nHow does the deconfounder work? While traditional
causal methods\nmeasure the effect of a single cause on an outcome\, many
modern\nscientific studies involve multiple causes\, different variables
whose\neffects are simultaneously of interest. The deconfounder uses the\n
correlation among multiple causes as evidence for unobserved\nconfounders\
, combining unsupervised machine learning and predictive\nmodel checking t
o perform causal inference. We demonstrate the\ndeconfounder on real-world
data and simulation studies\, and describe\nthe theoretical requirements
for the deconfounder to provide unbiased\ncausal estimates.\n\nThis is joi
nt work with Yixin Wang.

DESCRIPTION:Topic: Motivic Euler products in motivic statistics\n\nSpeaker:
Margaret Bilu\, New York University\n\nThe Grothendieck group of varietie
s over a field k is the quotient of the free abelian group of isomorphism
classes of varieties over k by the so-called cut-and-paste relations. It m
oreover has a ring structure coming from the product of varieties. Many pr
oblems in number theory have a natural\, more geometric counterpart involv
ing elements of this ring. Thus\, Poonen's Bertini theorem over finite fie
lds has a motivic analog due to Vakil and Wood\, which expresses the motiv
ic density of smooth hypersurface sections as the degree goes to infinity
in terms of a special value of Kapranov's zeta function. I will report on
joint work with Sean Howe\, providing a broad generalization of Vakil and
Wood's result\, which implies in particular a motivic analog of Poonen's B
ertini theorem with Taylor conditions\, as well as motivic analogs of many
generalizations and variants of Poonen's theorem. A key ingredient for th
is is a notion of motivic Euler product which allows us to write down cand
idate motivic probabilities.

DESCRIPTION:Topic: Equality Alone Does not Simulate Randomness\n\nSpeaker:
Marc Vinyals\, Technion\n\nRandomness can provide an exponential saving in
the amount of communication needed to solve a distributed problem\, and t
he canonical example of this is the equality function. However\, in many e
xamples where randomness helps\, having an efficient way to do hashing wou
ld be enough to solve the problem efficiently. Is hashing all there is to
randomness?\n\nIn this talk we show that hashing is not enough. More preci
sely\, we exhibit a function that can be solved efficiently using randomiz
ed protocols but not if we only allow access to an oracle that computes th
e equality function\, which models hashing.\n\nJoint work with Arkadev Cha
ttopadhyay and Shachar Lovett.

cultural heritage and history finds its expression in the twenty-four site
s that are included among the UNESCO World Heritage Sites\, with another f
ifty-six properties tentatively listed. For more than 400 years\, the Sasa
nian Empire constituted one of the leading world powers prior to the rise
of Islam\, and the significance of Iran for the formation of Islamic thoug

of minimizing a convex quadratic function with noisy gradient observation
s. While the NQM is simple enough to have closed-form dynamics for a varie
ty of optimizers\, it gives a surprising amount of insight into neural net
training phenomena. First\, we’ll look at the problem of adapting learnin
g rates using meta-descent (i.e. differentiating through the training dyna
mics). The NQM illuminates why short-horizon meta-descent objectives vastl
y underestimate the optimal learning rate. Second\, we’ll study how the be
havior of various neural net optimizers depends on the batch size. When is
it beneficial to use preconditioning? Momentum? Parameter averaging? Lear
ning rate schedules? The NQM can generate predictions in seconds which see
m to capture the qualitative behavior of large-scale classification conv n
ets and transformers.

DESCRIPTION:Tuesday\, January 28\n4:00 p.m.\nWolfensohn Hall\n\nIn her 1993
book Denying the Holocaust\, American academic Deborah E. Lipstadt called
British amateur historian David Irving “one of the most dangerous spokesm
en for Holocaust denial.” In response\, Irving sued Lipstadt for libel\, w
hich under British law required the defendant to prove the assertion. The
film Denial\, directed by Mick Jackson and released in 2016\, is the story
of that trial in 2000. The film stars Rachel Weisz as Deborah Lipstadt an
d Timothy Spall as David Irving. When Lipstadt is instructed by her lawyer
s to remain silent throughout the trial\, it causes her much internal conf
lict. It was her intention to confront Irving directly and provide the opp
ortunity for Holocaust survivors to give their own testimonies. Instead\,
expert witnesses had to prove that Irving had distorted evidence and that
gas chambers existed at Auschwitz. A lot was at stake: If Irving were succ
essful\, holocaust denial could become acceptable.\n\nThis film runs 1 hou
r and 49 minutes.\n\nProfessor Deborah Lipstadt will come to the IAS to ta
ke part in a panel discussion with Daniel Finkelstein (The Times\, UK)\, P
rofessor Julie Gottlieb\, and Dr. Karina Urbach on February 5th. Register
to attend the panel [here](/events/impact-feb2020).\n\nThis event is free
and open to the public. Please note that food and drink are not allowed in

oment of any family of automorphic L-functions on PGL(2) using regularized
diagonal periods of Eisenstein series\, following a strategy suggested by
Michel--Venkatesh. Applications include generalizations to the setting of
number fields of some results of Conrey--Iwaniec and Petrow--Young\, impr
oved estimates for representation numbers of ternary quadratic forms over
number fields\, and improvements to the prime geodesic theorem on arithmet
ic hyperbolic 3-folds.

DESCRIPTION:Topic: Coarse dynamics and partially hyperbolic diffeomorphisms
in 3-manifolds\n\nSpeaker: Rafael Potrie\, Universidad de la República\,
Uruguay\; Von Neumann Fellow\, School of Mathematics\n\nThe purpose of thi
s talk is to introduce the classification problem of partially hyperbolic
diffeomorphisms in dimension 3 (including introducing the concept of parti
ally hyperbolic diffeomorphisms and its relevance). The main goal will be
to explain the importance of the understanding of foliations in 3-manifold
s as well as pseudo-Anosov dynamics and hyperbolic geometry to this task.
The talk will touch on work by many people\, but focus on recent work join
t with T. Barthelme\, S. Fenley and S. Frankel.

DESCRIPTION:Topic: Supersingular main conjectures\, Sylvester's conjecture
and Goldfeld's conjecture\n\nSpeaker: Daniel Kriz\, Massachusetts Institut
e of Technology\n\nIn this talk\, I formulate and prove a new Rubin-type I
wasawa main conjecture for imaginary quadratic fields in which p is inert
or ramified\, as well as a Perrin-Riou type Heegner point main conjecture
for certain supersingular CM elliptic curves. These main conjectures and t
heir proofs are related to p-adic L-functions that I have previously const
ructed\, and have applications to two classical problems of arithmetic. Fi
rst\, I prove the 1879 conjecture of Sylvester stating that if p = 4\,7\,8
mod 9\, then x^3 + y^3 = p has a solution with x\,y rational numbers. Sec
ond\, combined with previous Selmer distribution results\, I show that 100
% of squarefree d = 5\,6\,7 mod 8 are congruent numbers\, thus establishin
g Goldfeld's conjecture for the family y^2 = x^3 - d^2x\, and solving the
congruent number problem in 100% of cases.

DESCRIPTION:Speaker: People’s Republic of Desire\n\nChina has seen an incr
edible rise in online streaming\, and live streamers often earn significan
t sums of money attracting and maintaining online followers. People’s Repu
blic of Desire\, a 2018 film produced\, directed\, and filmed by Hao Wu\,
documents an industry that was reported in 2018 as generating $4.4 billion
in revenue. The film follows two online streamers\, Shen Man\, a young fo
rmer nurse\, and Big Li\, previously a hotel security guard. In the New Yo
rk Times\, Ken Jaworowski writes that People’s Republic of Desire “is ulti
mately a contemplation of internet fame and social isolation\,” but it als
o signals new modes of making money that are characteristic of present tim
es. The film won Best Documentary Feature at the SXSW Film Festival in 201
8.\n\nThis film runs 1 hour and 35 minutes.\n\nA post-screening discussion
will be led by [Horacio Ortiz](/scholars/horacio-ortiz)\, Member in the S
chool of Social Science and Associate Professor at the Research Institute
of Anthropology\, East China Normal University\; and [Julia Chuang](/schol
ars/julia-chuang)\, Visitor in the School of Social Science and Assistant
Professor of Sociology\, Boston College.\n\nThis is the fourth film in the
series Economy and Society\, curated by the School of Social Science.\n\n
Reception to follow in the Fuld Hall Common Room\n\nThe event is free and
open to the public.\n\nPlease note that food and drink are not allowed in
Wolfensohn Hall.

DESCRIPTION:Wednesday\, February 19\, 2020\n5-6:30 pm\, White-Levy Room\nIn
stitute for Advanced Study\, Princeton\, NJ\n\nYemen’s war and humanitaria
n crisis are in the news\, but very little is known about the rich cultura
l heritage of the southwestern corner of Arabia throughout history. Also l
argely unknown are Yemen’s geographic and economic diversity or their impa
ct on recent events. Yemen’s diversity owes much to conquest\, trade\, and
migration between Yemen and Christian Ethiopia\, Sassanian and Islamic Ir
an\, Fatimid and Ayyubid Egypt\, Ottoman Turkey\, the African coast and So
utheast Asia. In this panel experts on different periods of Yemeni history
and its diverse contemporary contexts probe beyond current politics to sh
are their insights and discuss potentials for future scholarly research on
Yemen.\n\nPanelists\, currently scholars at IAS\, include: historians of
antiquity\, Glen Bowersock (IAS) and Christian Robin (Centre National de l
a Recherche Scientifique\, Paris)\, and of the Islamic era\, Hassan Ansari
(IAS)\, Sabine Schmidtke (IAS)\, Daniel Varisco (American Institute for Y
emeni Studies)\, and anthropologists Najwa Adra (IAS) and Nathalie Peutz (
New York University Abu Dhabi).\n\nThis event is part of the Near Eastern
Studies Workshops sponsored by Professor Sabine Schmidtke (IAS). RSVP to n

DESCRIPTION:Topic: An Improved Cutting Plane Method for Convex Optimization
\, Convex-Concave Games and its Applications\n\nSpeaker: Zhao Song\, Membe
r\, School of Mathematics\n\nGiven a separation oracle for a convex set $K
\subset \mathbb{R}^n$ that is contained in a box of radius $R$\, the goal
is to either compute a point in $K$ or prove that $K$ does not contain a
ball of radius $\epsilon$. We propose a new cutting plane algorithm that u
ses an optimal $O(n \log (\kappa))$ evaluations of the oracle and an addit
ional $O(n^2)$ time per evaluation\, where $\kappa = nR/\epsilon$.\n\n- Th
is improves upon Vaidya's $O( \text{SO} \cdot n \log (\kappa) + n^{\omega+
1} \log (\kappa))$ time algorithm [Vaidya\, FOCS 1989a] in terms of polyno
mial dependence on $n$\, where $\omega\n- This improves upon Lee-Sidford-W
ong's $O( \text{SO} \cdot n \log (\kappa) + n^3 \log^{O(1)} (\kappa))$ tim
e algorithm [Lee\, Sidford and Wong\, FOCS 2015] in terms of dependence on
$\kappa$.\n\nFor many important applications in economics\, $\kappa = \Om
ega(\exp(n))$ and this leads to a significant difference between $\log(\ka
ppa)$ and poly$(\log (\kappa))$. We also provide evidence that the $n^2$ t
ime per evaluation cannot be improved and thus our running time is optimal
.A bottleneck of previous cutting plane methods is to compute leverage sco
res\, a measure of the relative importance of past constraints.Our result
is achieved by a novel multi-layered data structure for leverage score mai
ntenance\, which is a sophisticated combination of diverse techniques such
as random projection\, batched low-rank update\, inverse maintenance\, po
lynomial interpolation\, and fast rectangular matrix multiplication. Inter
estingly\, our method requires a combination of different fast rectangular
matrix multiplication algorithms. Our algorithm not only works for the cl
assical convex optimization setting\, but also generalizes to convex-conca
ve games. We apply our algorithm to improve the runtimes of many interesti
ng problems\, e.g.\, Linear Arrow-Debreu Markets\, Fisher Markets\, and Wa
lrasian equilibrium.\n\nThis is a joint work with Haotian Jiang\, Yin Tat
Lee\, and Sam Chiu-wai Wong
