DESCRIPTION:Topic: DES survey\, photometric redshifts\, and related topics
\n\nEach week\, we hold a relatively informal seminar/discussion series\nw
ith an emphasis on extra-galactic and large-scale structure\nastrophysics.
\n\nDuring Galread a leader/visitor presents a recent paper to the\ndiscus
sion group. The PDF of the paper is projected onto a large\nscreen\, and a
guest explains the paper\, section by section\, in greater\ndetail than m
ay be explained within the text of the article. To aid\nwith discussion\,
only the article PDF is presented -- no\npowerpoint-style slides. Galread
discussions are very friendly and\ninteractive.

DESCRIPTION:Topic: On the Geometry of Uniform Meandric Systems\n\nSpeakers:
Ewain Gwynne\n\nAffiliation: The University of Chicago\n\nA meandric syst
em of size $n$ is the set of loops formed from two arc\ndiagrams (non-cros
sing perfect matchings) on $\{1\,\dots\,2n\}$\, one\ndrawn above the real
line and the other below the real line.\nEquivalently\, a meandric system
is a coupled collection of meanders of\ntotal size $n$. I will discuss a c
onjecture which describes the\nlarge-scale geometry of a uniformly sampled
meandric system of size\n$n$ in terms of Liouville quantum gravity (LQG)
decorated by certain\nSchramm-Loewner evolution (SLE) type curves. I will
then present\nseveral rigorous results which are consistent with this conj
ecture. In\nparticular\, a uniform meandric system admits macroscopic loop
s\; and\nthe half-plane version of the meandric system has no infinite pat
hs.\nNo prior knowledge about meanders\, SLE\, or LQG is needed to underst
and\nthe talk. Based on joint work with Jacopo Borga and Minjae Park.

DESCRIPTION:Topic: Harnessing the potential of radial velocity exoplanet su
rveys\n\nSpeakers: Arvind Gupta\n\nAffiliation: Pennsylvania State Univers
ity\n\nWith dedicated exoplanet surveys underway for multiple extreme\npre
cision radial velocity (EPRV) instruments\, such as the Terra\nHunting Exp
eriment on HARPS-3\, the near-future prospects of RV\nexoplanet science ar
e promising. These surveys' generous time\nallocations are expected to fac
ilitate the discovery of Earth analogs\naround bright\, nearby Sun-like st
ars. But survey success will depend\ncritically on the choice of observing
strategy\, which will determine\nthe survey's ability to mitigate known s
ources of noise and extract\nlow-amplitude exoplanet signals. I present an
analysis of the Fisher\ninformation content of EPRV survey simulations\,
accounting for the\nmost recent advances in our understanding of intrinsic
stellar\nvariability on both short and long timescales (i.e.\, oscillatio
ns and\ngranulation within individual nights\, and activity-induced variat
ions\nacross multiple nights) and capturing the correlated nature of these
\nsignals with Gaussian Process kernels. I describe the physical\ninterpre
tation of the Fisher information content in this context\, and\nI evaluate
the efficacy of common EPRV observing strategies as applied\nto a realist
ic survey.

DESCRIPTION:Topic: Sets With Small $l^1$ Fourier Norm\n\nSpeakers: Thomas B
loom\n\nAffiliation: University of Oxford\n\nA famous conjecture of Little
wood states that the Fourier transform of\nevery set of N integers has $l^
1$ norm at least log(N)\, up to a\nconstant multiplicative factor. This wa
s proved independently by\nMcGehee-Pigno-Smith and Konyagin in the 1980s.
This lower bound is the\nbest possible\, as it is achieved by an arithmeti
c progression. An\ninteresting question\, especially from the perspective
of additive\ncombinatorics\, is the 'inverse problem': what can we say abo
ut sets\nwhich are close to optimal\, say with $l^1$ norm at most 100 log(
N)? I\nwill discuss an inverse result of this type\, showing that (in a\nc
ertain sense) such sets are approximately the union of O(1) sets with\nsma
ll doubling.

: University of North Carolina\; Member\, School of Mathematics\n\nLet G b
e a simply-connected complex semisimple algebraic group and let\nC be a sm
ooth projective curve of any genus. Then\, the moduli space of\nsemistable
G-bundles on C admits so called determinant line bundles.\nE. Verlinde co
njectured a remarkable formula to calculate the\ndimension of the space of
generalized theta functions\, which is by\ndefinition the space of global
sections of a determinant line bundle.\nThis space is also identified wit
h the space of conformal blocks\narising in Conformal Field Theory\, which
is by definition the space\nof coinvariants in integrable highest weight
modules of affine\nKac-Moody Lie algebras. Various works notably by\nTsuc
hiya-Ueno-Yamada\, Kumar-Narasimhan Ramanathan\, Faltings\,\nBeauville-La
szlo\, Sorger and Teleman culminated into a proof of the\nVerlinde formula
.\n\nThe main aim of this course will be to give a complete and self\ncont
ained proof of this formula derived from the Propogation of\nVacua and th
e Factorization Theorem among others. The proof requires\ntechniques from
algebraic geometry\, geometric invariant theory\,\nrepresentation theory o
f affine Kac-Moody Lie algebras\, topology\, and\nLie algebra cohomology.
Some basic knowledge of algebraic geometry\nand representation theory of s
emisimple Lie algebras will be helpful\;\nbut not required. I will develop
the course from scratch recalling\nresults from different areas as we nee
d them.\n\nThe course will be based upon some parts of my book ‘Conformal
\nBlocks\, Generalized Theta Functions and the Verlinde Formula’\npublishe
d by the Cambridge Ubiversity Press this year. This course\nshould be suit
able for any one interested in interaction between\nalgebraic geometry\, r
epresentation theory\, topology and mathematical\nphysics.

\n\nSpeakers: Stephen Lubow\n\nAffiliation: Space Telescope Science Instit

a\ncoplanar\nstate. However\, recent theory and observations have surpris
ingly shown\nthat disks around\neccentric orbit binaries can evolve to a p
olar state in which the disk\nis perpendicular to the\norbit plane of the
binary. Such disks can in principle result in the\nformation\nof polar pla

DESCRIPTION:Topic: Smoothed Complexity of Local Max-Cut with Two Flips\n\nS
peakers: Xi Chen\n\nAffiliation: Columbia University\n\nMany algorithms an
d heuristics that work well in practice have poor\nperformance under the w
orst-case analysis\, due to delicate\npathological instances that one may
never encounter. To bridge this\ntheory-practice gap\, Spielman and Teng i
ntroduced the smoothed\nanalysis framework which can be viewed as a hybrid
of the classical\nworst-case and average-case analyses. Since then\, the
smoothed\nanalysis of algorithms and problems from combinatorial optimizat
ion\,\namong many other areas\, has been studied extensively.\n\nIn this t
alk\, we will review progress on the smoothed complexity of\nthe FLIP algo
rithm for local Max-Cut and binary Maximum Constraint\nSatisfaction Proble

is allowed to make two flips in each\nstep.\n\nBased on joint work with C

DESCRIPTION:Topic: Constraining the Composition and Formation Processes of
Planet Building Blocks: From Spitzer to JWST\n\nSpeakers: Cicero Lu\n\nAff
iliation: Johns Hopkins University\n\nDebris disks provide exciting opport
unities to study planet formation\nthrough the composition and architectur
e of planetary building blocks.\nThe Spitzer Space Telescope Infrared Spec
trograph (IRS)’s\ncomprehensive survey of more than 500 debris disks enabl
es us to study\nin detail the composition of dust grains in both the terre
strial\ntemperature zone and the exo-Kuiper belts. These mid-infrared spec
tra\nprovide direct evidence for planetesimal formation processes (such as
\ndifferentiation)\, opening doors to new questions on small planet\nforma
tion: Do planetesimal compositions in exoplanetary systems\ndisplay a spat
ial pattern similar to our solar system? Are extrasolar\nplanets assembled
from differentiated planetesimals\, similar to the\nsolar system asteroid
s\, or from undifferentiated materials? I begin\nwith an archetypal debris
disk\, beta Pictoris\, to showcase the\ncapability to constrain planetesi
mal properties as a function of their\nblackbody temperature\, a proxy for
stellocentric distance. Using the\nSpitzer IRS mid-IR spectrum\, I discov
er trends in beta Pic also\nstrikingly present in our solar system: the su
rfaces of large\nplanetesimals are more Fe-rich and processed interior to
beta Pic b's\norbit and become more Fe-poor and primordial exterior to bet
a Pic b's\norbit. Expanding on this work\, I investigate the commonality a
nd\ntimescale of the crust-mantle formation of extrasolar\, small\nEarth-l
ike planets. I analyze the most comprehensive debris disk\ncatalog based o
n Spitzer and Gaia DR3 data. I identify a group of\ndebris disks exhibitin
g spectroscopic evidence for hematite\, an\nindicator of water present in
differentiated terrestrial planets and\nsolar system asteroids. I will dis
cuss the implications of my findings\nfor the formation of small planets a
nd observational prospects with\nJWST.

DESCRIPTION:Topic: The reconstructed CMB lensing bispectrum\n\nSpeakers: Al
ba Kalaja \n\nAffiliation: VSI Groningen\n\nWeak gravitational lensing by
the intervening large-scale structure\n(LSS) of the Universe is the leadin
g non-linear effect on the\nanisotropies of the cosmic microwave backgroun
d (CMB). The integrated\nline-of-sight mass that causes the distortion --
known as lensing\nconvergence -- can be reconstructed from the lensed temp
erature and\npolarization anisotropies via estimators quadratic in the CMB
modes\,\nand its power spectrum has been measured from multiple CMB\nexpe
riments. Sourced by the non-linear evolution of structure\, the\nbispectru
m of the lensing convergence provides additional information\non late-time
cosmological evolution complementary to the power\nspectrum. However\, wh
en trying to estimate the summary statistics of\nthe reconstructed lensing
convergence\, a number of noise-biases are\nintroduced\, as previous stud
ies have shown for the power spectrum. In\nthis talk\, I will discuss how
we compute the leading noise biases of\nthe bispectrum in the flat-sky lim
it\, and how these results compare to\nsimulations.

DESCRIPTION:Topic: Introduction to Natural Quasirandomness: Unique Colorabi
lity and Orderability\n\nSpeakers: Leonardo Coregliano\n\nAffiliation: Mem
ber\, School of Mathematics\n\nThe theory of graph quasirandomness studies
sequences of graphs that\n'look like' samples of the Erdős--Rényi random
graph. The upshot of\nthe theory is that several ways of comparing a seque
nce with the\nrandom graph turn out to be equivalent. For example\, two eq
uivalent\ncharacterizations of quasirandom graph sequences is as those tha
t are\nuniquely colorable or uniquely orderable\, that is\, all colorings
\n(orderings\, respectively) of the graphs 'look approximately the same'.
\n\nThe theory of graph quasirandomness was one of the main motivations\nf
or the development of the theory of limits of graph sequences\,\ngraphons.
Since the theory of graphons has a generalization to\narbitrary combinato
rial objects in the form of the theories of flag\nalgebras and theons\, it
is natural to ask for a theory of\nquasirandomness for arbitrary combinat
orial objects.\n\nIn this talk\, I will introduce the theory of natural qu
asirandomness\,\nwhich provides such generalization. The talk will focus o
n the first\nmain result of natural quasirandomness: the equivalence of un
ique\ncolorability and unique orderability for arbitrary combinatorial\nob
jects. Although the theory heavily uses the language and\ntechniques of c
ontinuous combinatorics from both flag algebras and\ntheons\, no familiari
ty with the topic is required as I will also\nbriefly review all definitio
ns and theorems necessary.

DESCRIPTION:Topic: Topics in Model Theory: Stability\, Amalgamation\, and F
inite Fields\n\nSpeakers: Alexis Chevalier\n\nAffiliation: Member\, School
of Mathematics\n\nThe goal of this learning seminar is to explain some of
the core model\ntheoretic notions which are behind Tao’s algebraic regula
rity lemma\nabout definable graphs in finite fields (Tao 2012).\n\nWe will
assume minimal knowledge of model theory and introduce local\nstability t
heory and amalgamation problems from scratch. Stability is\na combinatoria
l notion imposed on formulas which determines rich model\ntheoretic struct
ure. Amalgamation is a model theoretic property which\ndescribes how the b
ehaviour of small sets of variables can determine\ntheir global behaviour.
\n\nWe will see that these distinct notions interact in surprising ways in
\nthe theory of pseudofinite fields. If time permits\, we will give two\nd
ifferent proofs of Tao’s algebraic regularity lemma\, one relying on\nthe
geometry of Hilbert spaces\, and the other relying on\n3-amalgamation in a
lgebraically closed fields.

rd\n\nAffiliation: Member\, School of Mathematics\n\nGiven any non-negativ
e function $\f:\mathbb{Z}\rightarrow\mathbb{R}$\,\nit follows from basic e
rgodic ideas that either 100% of real numbers\n$\alpha$ have infinitely ma
ny rational approximations $a/q$ with $a\,q$\ncoprime and $|\alpha-a/q| 1e6 Msun are t
hought to be\nprogenitors of globular clusters (GCs). Their births however
are\nseldomly seen in the local Universe. Given radiation and kinetic\nfe
edbacks that regulate star formation\, contribution to cosmic\nreionizatio
n through efficient Lyman continuum (LyC) escape\, and the\npuzzle of chem
ically peculiar populations found in most globular\nclusters\, much is to
be understood about what happens in the immediate\nenvironment of these yo
ung systems that host a large number of massive\nstars. I will present a p
hotometric and spectroscopic study of a\nhighly magnified\, LyC-leaking su
per star cluster with a mass ~1e7 Msun\nand an age ~3–4 Myr\, in a lensed
Cosmic Noon galaxy. We found dense\nphotoionized clouds at just ~ 10 pc th
at are highly enriched with\nnitrogen. We theorize that these dense clouds
originate from massive\nstar ejecta and may have implications for the ori
gin of chemically\npeculiar stars. I will also discuss another lensed star
cluster in the\nsame galaxy that has a lensing anomaly and show intense F
e III\nfluorescent emissions pumped by Lyman alpha radiation. I discuss a
\ntheory of trapped Lyman alpha radiation to explain this unusual\nspectra
l phenomenon\, which again hints at an extremely gas-enshrouded\nenvironme
nt caused by massive star ejecta inside a compact young super\nstar cluste
r. These findings call for a better understanding of the\ninterplay betwee
n radiation\, gravity\, gas and massive star evolution\nin young super sta

DESCRIPTION:Topic: Limit Profiles of Reversible Markov Chains\n\nSpeakers:
Evita Nestoridi\n\nAffiliation: Stony Brook University\, Princeton Univers

the\nrandom transpositions shuffle\; pick two cards uniformly at random an
d\nswap them. They introduced a Fourier analysis technique to prove that\n
it takes $1/2 n \log n$ steps to shuffle a deck of $n$ cards this way.\nRe
cently\, Teyssier extended this technique to study the exact shape of\nthe
total variation distance of the transition matrix at the cutoff\ntime fro
m the stationary measure\, giving rise to the notion of a limit\nprofile.
In this talk\, I am planning to discuss a joint work with\nOlesker-Taylor\
, where extend the above technique from conjugacy\ninvariant random walks
to general\, reversible Markov chains. I will\nalso present a new techniqu
e that allows to study the limit profile of\nstar transpositions\, which t
urns out to have the same limit profile as\nrandom transpositions\, and I
will discuss open questions and\nconjectures.

DESCRIPTION:Topic: Branched Regularity Theorems for Stable Minimal Hypersur
faces Near Classical Cones of Density Q+1/2\n\nSpeakers: Paul Minter\n\nAf
filiation: Veblen Research Instructor\, School of Mathematics\n\nThe prese
nce of branch points and so-called density gaps heavily\ncomplicates the r
egularity theory for minimal submanifolds or\, more\nprecisely\, stationar
y integral varifolds. Density gaps illustrate a\nmismatched symmetry betwe
en nearby varifolds\, meaning that one cannot\nin general hope to infer fr
om a tangent cone the local singularity\nstructure of a stationary integra
l varifold. Branch points are a\nhighly degenerate situation\, where singu
larities disappear in the\nlimiting tangent cone and are replaced with reg
ions of higher $(i.e.\,\n>1)$ multiplicity. It is still an open question a
s to whether the set\nof branch points can have positive measure within th
e support of a\nstationary integral varifold. In many of the regularity re
sults known\nfor certain classes of stationary integral varifolds\, branch
points\nare either ruled out a priori\, or\, after significant work\, are
ruled\nout a posteriori. When density gaps may occur\, usually one can pr
ove\nthat the singular set in a density gap region is small and use this t
o\nsomehow rule out density gaps. In this talk\, I will discuss recent\nwo
rk concerning a regularity question where both branch points can\noccur an
d there is no size assumption on the singular set within a gap\nregion. Th
e main result is that\, for a large class of stationary\nintegral varifold
s which have stable smoothly embedded parts\, near\ncertain so-called 'cla
ssical cones'\, a varifold is a multi-valued\ngeneralised-$C^{1\,\alpha}$
perturbation of the classical cone. In\nparticular\, if such a cone arises
as a tangent cone to the varifold\,\nthen the points of density equal to
that of the cone form a\n$C^{1\,\alpha} $submanifold. This work builds on
earlier work by the\nspeaker and Neshan Wickramasekera concerning the loca
l structure of\nbranched stable minimal hypersurfaces.

G-bundles on C admits so called determinant line bundles.\nE. Verlinde co
njectured a remarkable formula to calculate the\ndimension of the space of
generalized theta functions\, which is by\ndefinition the space of global
sections of a determinant line bundle.\nThis space is also identified wit
h the space of conformal blocks\narising in Conformal Field Theory\, which
is by definition the space\nof coinvariants in integrable highest weight
modules of affine\nKac-Moody Lie algebras. Various works notably by\nTsuc
hiya-Ueno-Yamada\, Kumar-Narasimhan Ramanathan\, Faltings\,\nBeauville-La
szlo\, Sorger and Teleman culminated into a proof of the\nVerlinde formula
.\n\nThe main aim of this course will be to give a complete and self\ncont
ained proof of this formula derived from the Propogation of\nVacua and th
e Factorization Theorem among others. The proof requires\ntechniques from
algebraic geometry\, geometric invariant theory\,\nrepresentation theory o
f affine Kac-Moody Lie algebras\, topology\, and\nLie algebra cohomology.
Some basic knowledge of algebraic geometry\nand representation theory of s
emisimple Lie algebras will be helpful\;\nbut not required. I will develop
the course from scratch recalling\nresults from different areas as we nee
d them.\n\nThe course will be based upon some parts of my book ‘Conformal
\nBlocks\, Generalized Theta Functions and the Verlinde Formula’\npublishe
d by the Cambridge Ubiversity Press this year. This course\nshould be suit
able for any one interested in interaction between\nalgebraic geometry\, r
epresentation theory\, topology and mathematical\nphysics.

said\ninstabilities can constrain the presence of additional degrees of\n
freedom. \n * The curvature frontier: The nonlinear regime of binary mer

DESCRIPTION:Topic: Lozenge Tilings and the Gaussian Free Field on a Cylinde
r\n\nSpeakers: Marianna Russkikh\n\nAffiliation: California Institute of T
echnology\n\nWe discuss new results on lozenge tilings on an infinite cyli
nder\,\nwhich may be analyzed using the periodic Schur process introduced
by\nBorodin. Under one variant of the q^vol measure\, corresponding to\nra
ndom cylindric partitions\, the height function converges to a\ndeterminis
tic limit shape and fluctuations around it are given by the\nGaussian free
field in the conformal structure predicted by the\nKenyon-Okounkov conjec
ture. Under another variant\, corresponding to an\nunrestricted tiling mod
el on the cylinder\, the fluctuations are given\nby the same Gaussian free
field with an additional discrete Gaussian\nshift component. Fluctuations
of the latter type have been previously\nconjectured for tiling models on
planar domains with holes.

DESCRIPTION:Topic: Professor Richard Shiffrin on Human Memory\n\nSpeakers:
Richard Shiffrin\n\nAffiliation: Indiana University\n\nWhat are the chief
causes of forgetting? Several causes are well\nestablished and accepted: F
or short-term memory\, limited capacity is a\ncause of forgetting. There a
re reasons to believe long-term memory\ndoes not suffer from a similar cap
acity limitation and that memory\ntraces remain more or less permanent _IF
UNDISTURBED_. Nonetheless\nthose traces may exhibit forgetting due to fai
lures of retrieval.\nAccepted causes of retrieval failure are _COMPETITION
_ (aka\ninterference\, cue overload)\, _CONTEXT CHANGE_\, and _ADDITION TO
TRACES\nTHAT OCCUR WHEN THEY ARE RETRIEVED_. \n\nBob Bjork\, Elizabeth Bj
ork and Michael Anderson highlighted another\npossible cause of long-term
forgetting in a 1994 paper reporting a\ncued recall paradigm that exhibite
d Retrieval Induced Forgetting\n(RIF). They argued that the RIF was due to
_INHIBITION_ causing a\nreduction in trace strength of a trace that is re
trieved but is not\nthe one desired. Ashleigh Maxcey and colleagues publis
hed several\npapers using a design like that of Bjork et al.\, but using r
ecognition\nrather than cued recall. They also found RIF\, and also interp
reted\nthat as due to inhibition. \n\nWe report two tests of inhibition\,
one in the recognition paradigm and\none in the cued recall paradigm\, fin
ding no RIF in either\, showing\nthat inhibition does not cause forgetting
or is at most a minor\ncontributor to forgetting.

DESCRIPTION:Topic: Strong XOR Lemma for Communication with Bounded Rounds\n
\nSpeakers: Huacheng Yu\n\nAffiliation: Princeton University\n\nIn this ta
lk\, we show a strong XOR lemma for bounded-round two-player\nrandomized c
ommunication. For a function f:X×Y→{0\,1}\, the\nn-fold XOR function f^⊕n
:X^n×Y^n→{0\,1} maps n input pairs\n(x_1\,...\,x_n)\, (y_1\,...\,y_n) to t
he XOR of the n output bits\nf(x_1\,y_1)⊕...⊕f(x_n\, y_n). We prove that
if every r-round\ncommunication protocols that computes f with probability
2/3 uses at\nleast C bits of communication\, then any r-round protocol th
at\ncomputes f^⊕n with probability 1/2+exp(-O(n)) must use\nn(r^{-O (r)}C-
1) bits. When r is a constant and C is sufficiently\nlarge\, this is Omeg
a(nC) bits. It matches the communication cost\nand the success probabilit
y of the trivial protocol that computes the\nn bits f(x_i\,y_i) independen
tly and outputs their XOR\, up to a\nconstant factor in n. \n\nA similar X
OR lemma has been proved for f whose communication lower\nbound can be obt
ained via bounding the discrepancy [Shaltiel03]. By\nthe equivalence betwe
en the discrepancy and the correlation with\n2-bit communication protocols
\, our new XOR lemma implies the previous\nresult.

Numbers\n\nSpeakers: Anna Wienhard\n\nAffiliation: Princeton University\;
Member\, School of Mathematics\n\nMarkov numbers are positive integers tha
t appear in solutions of the\nequation x^2+y^2+z^2=3xyz. They also appear
naturally when one tries\nto parametrize positive $SL_2(R)$-local systems
on a one punctured\ntorus. In this talk I will explain that there are gene

e groups. I\nwill then discuss a special case which is related to groups o
f type\n$SL_2$ over non-commutative rings and describe the positive struct

ematics\; Massachusetts Institute of Technology\n\nCome play with 250 phys
ical wooden blocks and join us in thinking\nabout a simple open problem fo
r dimers in 3D. No prior knowledge\nrequired. We’ll start with an ~10 minu
te presentation explaining the\nproblem and then suggest some things for e
veryone to try to construct\nwith the blocks.\n\nA bit more detail: a dime
r tiling of a region R contained in Z^d is a\ntiling by blocks which are l
ength 2 in one dimension and length 1 in\nall others (e.g. like dominos in
2D or like bricks in 3D). In 2D\,\nthere is a local move called a flip (a
flip takes two parallel tiles\nand rotates them\, e.g. || becomes = ). It
turns out that any two dimer\ntilings of the same simply connected planar
region are connected by a\nsequence of flips. In 3D\, dimer tilings are n
ot connected under flips\neven on the 3x3x2 box. Adding another local move
called\na _trit _involving 3 tiles instead of 2\, it’s an open question\n
whether dimer tilings of the LxNxM box are connected under flips and\ntrit
s if L\,M\,N > 2.

unication complexity at\nleast the (exact\, approximate\, and threshold) d
egree of f. This\nparticular technique was developed by Sherstov\, Razboro

lower bounds\, the technique has\napplications in many areas\, especially

DESCRIPTION:Topic: Almost all Dynamically Syndetic Sets are Multiplicativel
y Thick\n\nSpeakers: Daniel Glasscock\n\nAffiliation: University of Massac
husetts Lowell\n\nIf a set of integers is syndetic (finitely many translat
es cover the\nintegers)\, must it contain two integers whose ratio is a sq
uare? No\none knows. In the broader context of the disjointness between
\nadditive and multiplicative configurations and actions in ergodic\nRamse
y theory\, it makes sense to ask similar questions about\ndynamically synd
etic sets\, those sets that contain the visit times of\na point to an open
set in a minimal topological dynamical system. \nThe main result of the t
alk is that almost every dynamically syndetic\nset is multiplicatively ver
y rich: it is “thick” in some coset of\na multiplicative subsemigroup. We
will discuss some applications: a\n“thick-starters” van der Waerden theor
em\; the existence of\nmultiplicative structure in sets of the form A – A
+ t\; and the\ntopological disjointness of minimal niltranslations and min
imal\,\naperiodic multiplicative actions. Time permitting\, we will discu
ss\nthree tools that proved useful in the topic: the prolongation relation
\n(the closure of the orbit-closure relation) developed by Auslander\,\nAk
in\, and Glasner\; the theory of rational points and polynomials on\nnilma
nifolds developed by Leibman\, Green\, Tao\; and the machinery of\ntopolog
ical characteristic factors developed recently by Glasner\,\nHuang\, Shao\
, Weiss\, and Ye. This talk is based on work\nin https://arxiv.org/abs/22

ties of their companion protoplanetary disks. A massive disk with\nan inne
r truncation may become eccentric due to non-adiabatic effects\nassociated
with gas cooling\, and can retain its eccentricity in\nlong-lived coheren
tly-precessing eccentric modes\; as the disk\ndisperses\, the inner planet
will encounter a secular resonance with\nthe eccentric disk when the plan
et and the disk have the same apsidal\nprecession rates\; the eccentricity
of the planet is then excited to a\nlarge value as the system goes throug
h the resonance. In this talk\, I\nwill discuss how disks may spontaneousl
y become eccentric through\neccentric mode instability. Then\, I will pres
ent an approximate\nsecular dynamics model to calculate the long-term evol
ution of the\n'planet + dispersing eccentric disk' system. Our calculation
s find\nthat the planet can attain a large eccentricity (between 0.1 and 0
.6)\nin this model. This eccentricity excitation can be understood in term
s\nof the mode conversion (``avoided crossing'') phenomenon associated\nwi
th the evolution of the 'planet + disk' eccentricity eigenstates.

DESCRIPTION:Topic: Topic 1: Tidal deformability from scattering and the rol
e of analytic continuation Topic 2: TBA\n\nSpeakers: Gaston Creci Keinbaum
and Heyang Long\n\nAffiliation: Utrecht University and Ohio State Univer
sity\n\nAbstract 1: The tidal response of a compact object is a key\ngravi
tational-wave observable encoding information about its interior.\nThis li
nk is subtle due to the nonlinearities of general relativity. I\nwill show
that considering a scattering process bypasses challenges\nwith potential
ambiguities\, as the tidal response is determined by the\nasymptotic in-
and outgoing waves at null infinity. As an application\nof the general met
hod\, I will consider scalar waves scattering off a\nnonspinning black hol
e and demonstrate that the low-frequency\nexpansion of the tidal response
reproduces known results for the Love\nnumber and absorption. In addition\
, I will discuss the definition of\nthe response based on gauge-invariant
observables obtained from an\neffective action description. I will introdu
ce this effective action\nusing Newtonian physics\, and furthermore clarif
y the role of analytic\ncontinuation for robustly (i) extracting the respo
nse and the physical\ninformation it contains\, and (ii) distinguishing hi
gh-order\npost-Newtonian corrections from finite-size effects in a binary
\nsystem. This work is important for interpreting upcoming\ngravitational-
wave data for subatomic physics of ultradense matter in\nneutron stars\, p
robing black holes and gravity\, and looking for\nbeyond-standard-model fi
elds.\n\nAbstract 2: TBA

DESCRIPTION:Topic: The Hypergraph Container Method\, Partition Containers\,
and Algorithmic Applications\n\nSpeakers: Or Zamir\n\nAffiliation: Visito
r\, School of Mathematics\n\nThe recently-discoverd Hypergraph Container M
ethod (Saxton and\nThomason\, Balogh\, Morris and Samotij)\, generalizing
an earlier version\nfor graphs (Kleitman and Winston)\, is used extensivel
y in recent years\nin extremal and probabilistic combinatroics. In essenc
e\, it shows\nthat independent sets in regular-enough dense hypergraphs mu
st be\nclustered in some fashion.\n\nIn this seminar we will give an overv
iew of this method and then\npresent its first algorithmic applications.
We use it\nalgorithmically to convert algorithms into faster algorithms fo
r\nregular or dense input instances. An important component of our work\n
is the generalization of graph containers to Partition Containers. \nWhile
standard containers apply to a single independent set\, partition\ncontai
ners explore the structure of several independent sets at the\nsame time.
\n\nOur main application resolves a major open problem about Graph\nColori
ng algorithms\, for regular graphs. The chromatic number of a\ngraph can
be computed in $2^n$ time (Husfeldt et al.). For $k<=6$ it\nis known that
$k$-coloring can be solved in $(2-eps)^n$ time for some\n$eps>0$. For la
rger values of $k$ improvements are only known for\nsparse graphs. We sho
w that $k$-coloring of regular graphs can be\nsolved in $(2-eps_k)^n$ time
\, where $eps_k>0$ for every $k$. We\nstress that the degree of the regul
ar graphs is unbounded. \n\nAs another application\, we give the first im
proved $k$-SAT algorithm\nfor dense formulas. We give additional applicat
ions including faster\nalgorithms for unweighted and weighted Maximum Inde
pendent Set\nalgorithms in regular graphs.

DESCRIPTION:Topic: Verlinde Dimension Formula for the Space of Conformal Bl
ocks and the Moduli of G-bundles\n\nSpeakers: Shrawan Kumar\n\nAffiliation
: University of North Carolina\; Member\, School of Mathematics\n\nLet G b
e a simply-connected complex semisimple algebraic group and let\nC be a sm
ooth projective curve of any genus. Then\, the moduli space of\nsemistable
G-bundles on C admits so called determinant line bundles.\nE. Verlinde co
njectured a remarkable formula to calculate the\ndimension of the space of
generalized theta functions\, which is by\ndefinition the space of global
sections of a determinant line bundle.\nThis space is also identified wit
h the space of conformal blocks\narising in Conformal Field Theory\, which
is by definition the space\nof coinvariants in integrable highest weight
modules of affine\nKac-Moody Lie algebras. Various works notably by\nTsuc
hiya-Ueno-Yamada\, Kumar-Narasimhan Ramanathan\, Faltings\,\nBeauville-La
szlo\, Sorger and Teleman culminated into a proof of the\nVerlinde formula
.\n\nThe main aim of this course will be to give a complete and self\ncont
ained proof of this formula derived from the Propogation of\nVacua and th
e Factorization Theorem among others. The proof requires\ntechniques from
algebraic geometry\, geometric invariant theory\,\nrepresentation theory o
f affine Kac-Moody Lie algebras\, topology\, and\nLie algebra cohomology.
Some basic knowledge of algebraic geometry\nand representation theory of s
emisimple Lie algebras will be helpful\;\nbut not required. I will develop
the course from scratch recalling\nresults from different areas as we nee
d them.\n\nThe course will be based upon some parts of my book ‘Conformal
\nBlocks\, Generalized Theta Functions and the Verlinde Formula’\npublishe
d by the Cambridge Ubiversity Press this year. This course\nshould be suit
able for any one interested in interaction between\nalgebraic geometry\, r
epresentation theory\, topology and mathematical\nphysics.

DESCRIPTION:Topic: The fate of the merger remnant in GW170817 and its impri

on: University of California Santa Cruz\n\nOn August 17\, 2017\, LIGO/Virg
o detected the first gravitational waves\nfrom merging neutron stars. This
event\, known as GW170817 was\naccompanied by observations all over the e
lectromagnetic spectrum. \nThe peculiar gamma-ray burst that followed the
merger in GW170817\, is\nunlike any gamma-ray burst observed before. In or
der to explain the\nafterglow observations\, there is a need for the jet l
aunched after the\nmerger to have structure\, which is a natural consequen
ce of the\ninteraction of the jet with the ambient medium. In this talk\,
I will\nshow special relativistic simulations of the interaction of the je
t\nwith several outflows launched during the merger and compare the\nsimul
ations to the observation. I will then use the results in order\nto constr
ain key properties of the merger\, such as the delay time\nbetween the mer
ger and the collapse to a black hole.

ost allows to convert a weak learner\, that\nis an algorithm that produces
a hypothesis which is slightly better\nthan chance\, into a strong learne
r\, achieving arbitrarily high\naccuracy when given enough training data.
We present a new algorithm\nthat constructs a strong learner from a weak l
earner but uses less\ntraining data than AdaBoost and all other weak to st
rong learners to\nachieve the same generalization bounds. A sample complex
ity lower\nbound shows that our new algorithm uses the minimum possible am
ount of\ntraining data and is thus optimal. Hence\, this work settles the
sample\ncomplexity of the classic problem of constructing a strong learner
\nfrom a weak learner. \n\nThis work was accepted at NeurIPS’22 and is joi

DESCRIPTION:Topic: New windows into cosmic history\n\nSpeakers: Gabriela Sa
to-Polito\n\nThe aggregate light emitted by all extragalactic sources can
be\nmeasured either as an absolute intensity or through its spatial\nfluct
uations\; these are known as line-intensity mapping (LIM) when a\nparticul
ar line transition is targeted. I will discuss how absolute\nintensity mea
surements can be used both to learn about galaxy\nevolution and to investi
gate the presence of more speculative sources\nof radiation\, such as deca
ying dark matter. I will then discuss how\nthe unique characteristics of i
ntensity mapping measurements (e.g.\nwide redshift coverage\, sensitivity
to faint sources\, and mapping\nspeed) may enable a variety of scientific
goals and some of the\nchallenges in realizing them\, along with a numeric
al framework to\nmodel LIM within the broader context of probes of large-s
cale\nstructure.

DESCRIPTION:Topic: The Other Galois Representation of an Elliptic Curve\n\n
Speakers: Michael Larsen\n\nAffiliation: Indiana University\; Member\, Sch
ool of Mathematics\n\nLet $E$ be an elliptic curve defined over $\Q$. The
$\bar\Q$-points\nof $E$ form an abelian group on which the Galois group $
G_{\Q} =\n\Gal(\bar\Q/\Q)$ acts. The usual Galois representation associat
ed to\n$E$ captures the action of $G_{\Q}$ on the points of finite order.
\n However\, one could also look at the action of $G_{\Q}$ on the free\npa
rt of $E(\bar\Q)$. This infinite-dimensional representation\nencodes a gr
eat deal of interesting arithmetic information. I will\nstate a conjectur
e concerning this other Galois representation and\npresent supporting evid
ence from probability theory\, Ramsey theory\,\nalgebraic geometry\, and n
umber theory.

DESCRIPTION:Topic: Symplectic Geometry of Anosov Flows and their Invariant
Volume Forms\n\nSpeakers: Surena Hozoori\n\nAffiliation: University of Roc
hester\n\nSince their introduction in the early 1960s\, Anosov flows have
defined\nan important class of dynamics\, thanks to their many interesting
\nchaotic features and rigidity properties. Moreover\, their topological\n
aspects have been deeply explored\, in particular in low dimensions\,\ntha
nks to the use of foliation theory in their study. Although the\nconnectio
n of Anosov flows to contact and symplectic geometry was\nnoted in the mid
1990s by Mitsumatsu and Eliashberg-Thurston\, such\ninterplay has been le
ft mostly unexplored. I will present some recent\nresults on the contact a
nd symplectic geometric aspects of Anosov\nflows in dimension 3\, includin
g in the presence of an invariant volume\nform\, which is known to have gr
ave consequences for the dynamics of\nthese flows. Time permitting\, the i
nterplay of Anosov flows with Reeb\ndynamics\, Liouville geometry and surg
ery theory will be briefly\ndiscussed as well.

DESCRIPTION:Topic: Online List Labeling: Breaking the log$^2$ n Barrier\n\n
Speakers: Nicole Wein\n\nAffiliation: Rutgers University\n\nThe online lis
t labeling problem is a basic primitive in data\nstructures. The goal is t
o store a dynamically-changing set of n items\nin an array of m slots\, wh
ile keeping the elements in sorted order. To\ndo so\, some items may need
to be moved over time\, and the goal is to\nminimize the number of items m
oved per insertion/deletion. When $m =\nCn$ for some constant $C>1$\, an u
pper bound of $O(log^2 n)$items moved\nper insertion/deletion has been kno
wn since 1981. There is a matching\nlower bound for deterministic algorith
ms\, but for randomized\nalgorithms\, the best known lower bound is Omega(
log n)\, leaving a gap\nbetween upper and lower bounds. We improve the upp
er bound\, providing\na randomized data structure with expected $O(log^{3/
2} n)$ items moved\nper insertion/deletion.\n\nJoint work with Michael Ben

DESCRIPTION:Topic: Conformally Invariant Fields out of Brownian Loop Soups
\n\nSpeakers: Wei Qian\n\nAffiliation: City University of Hong Kong\n\nFor
each central charge $c\in (0\,1]$\, we construct a conformally\ninvariant
field which is a measurable function of the local time field\n$\mathcal{L
}$ of the Brownian loop soup with intensity $c$ and i.i.d.\nsigns given to
each cluster. This field is canonically associated to\n$\mathcal{L}$\, in
a sense which is similar to the isomorphism theory\nthat associates the G
aussian free field to the loop soup with critical\nintensity. Isomorphisms
between Brownian motions and random fields\nwere previously developed by
Symanzik\, Brydges-Fröhlich-Spencer\,\nDynkin and Le Jan in several differ
ent settings.\n\nIn a key intermediate step\, we obtain the crossing expon
ent for the\nevent that a cluster in the subcritical loop soup passes near
a given\npoint. Among other things\, it allows us to deduce that the Mink
owski\ngauge function of a cluster in a loop soup with intensity $c\in\n(0
\,1)$\, which is $t^2 f(t)$ for some $f(t)=|\log t|^{1-c/2+o(1)}$.\n\nIn t
he end\, I will present several conjectures about this family of\nfields.
This talk is based on joint works in progress with Antoine\nJego (EPFL) an
d Titus Lupu (CNRS).

DESCRIPTION:Topic: How Small Can a Group or a Graph be to Admit a Non-Trivi
al Poisson Boundary?\n\nSpeakers: Anna Erschler\n\nAffiliation: École norm
ale supérieure\n\nWe review results about random walks on groups\, discuss
ing results and\nconjectures relating critical constant for recurrence/tra
nsience\,\ngrowth and Poisson boundary. \n\nMuch less is known about behav
ior of random walks on Schreier graphs.\nSince any regular graph is a Schr
eier graph\, well known\ncounterexamples show that these random walks\, in
contrast with group\ncase\, do not enjoy structural results such as entr
opy criterion. It\nis well known that for 'very small' graphs (of at most
quadratic\ngrowth) simple random walks are recurrent\, and thus have trivi
al\nboundary. It turns out that if we allow infinitely supported\nmeasure
s\, the properties of the random walk can reflect better some\ngroup theor
etic properties. \n\nIn a work in progress with J. Frisch\, N. Matte Bon a
nd T. Zheng we\nstudy random walks on Schreier graphs. Our examples inclu
de random\nwalks on Grigorchuk groups. These groups\, starting from being
a\ncounter example to Milnor question about subexponential growth\, are\nk
nown to be a source of somehow counterintuitive phenomena. Studying\ntheir
Schreier graphs\, we show that even the smallest example among\npossible
infinite Schreier graphs\, the ray\, may admit (infinitely\nsupported ) m
easures with non-trivial boundary. Such measures can be\nchosen to be symm
etric\, of finite entropy with the boundary isomorphic\nto standard Lebesg
ue space.

DESCRIPTION:Topic: Optimization-Friendly Generic Mechanisms Without Money\n
\nSpeakers: Mark Braverman\n\nAffiliation: Princeton University\n\nOur goa
l is to develop a generic framework for converting modern\ngradient-descen
t based optimization algorithms into mechanisms where\ninputs come from se
lf-interested agents.\n\nWe focus on aggregating preferences from n player
s in a context\nwithout money. Special cases of this setting include votin
g\,\nallocation of items by lottery\, and matching. Our key technical\ncon
tribution is a new meta-algorithm we call APEX (Adaptive Pricing\nEqualizi
ng Externalities). The framework is sufficiently general to be\ncombined w
ith any optimization algorithm that is based on local\nsearch.\n\nIn the t
alk I'll outline the algorithm\, and open problem/research\ndirections tha
t it raises.\n\nAs an application of the framework\, I will discuss a spec
ial case of\napplying the framework to the problem of one-sided allocation
with\nlotteries. In this case\, we obtain a strengthening of the 1979 res
ult\nby Hylland and Zeckhauser on allocation via a competitive equilibrium
\nfrom equal incomes (CEEI). The [HZ79] result posits that there is a\n(fr
actional) allocation and a set of item prices such that the\nallocation is
a competitive equilibrium given prices. We further show\nthat there is al
ways a reweighing of the players' utility values such\nthat running the st
andard unit-demand VCG with reweighed utilities\nleads to a HZ-equilibrium
prices. Interestingly\, not all HZ\ncompetitive equilibria come from VCG
prices.

DESCRIPTION:Topic: Topic 1: Towards Optimal Measurement of the Neutrino Mas
s using Large-Scale Structure\; Topic 2: Cosmological constraints from the
void size function – a new perspective on the rising tensions\n\nSpeakers
: Adrian Bayer and Sofia Contarini\n\nAffiliation: University of Californi
a\, Berkeley and University of Bologna\n\nABSTRACT 1: Massive neutrinos su
ppress the growth of cosmic structure\non small\, non-linear\, scales. The
re is thus much interest in using\nstatistics beyond the power spectrum to
tighten constraints on the\nneutrino mass by extracting additional inform
ation from these\nnon-linear scales. In this talk\, I will first explore t
he information\nin the non-linear matter field using the Quijote simulatio
ns. I will\nshow how the matter power spectrum\, halo mass function\, and
void size\nfunction can be combined to break degeneracies between cosmolog
ical\nparameters and give considerably tighter constraints on the neutrino
\nmass compared to the power spectrum alone. I will then explore how\nmuch
of this non-linear information we can expect to find in upcoming\nsurveys
which observe galaxy clustering and weak lensing. In turn\, I\nwill intro
duce the Half Dome simulations as a tool to study\ncross-correlations betw
een large-scale structure and the cosmic\nmicrowave background. Finally\,
I will motivate field-level inference\nwith differentiable forward modelin
g as a method to optimally extract\ninformation from cosmic structure.\n\n
ABSTRACT 2: Observing the Universe at large scales\, a considerable\nfract
ion of its volume is dominated by almost empty space. Alongside\nthe lumin
ous filamentary structures of the Universe\, there are vast\nunderdense zo
nes commonly known as cosmic voids. Although essentially\ndevoid of matter
\, voids enclose fundamental information about the\ncosmological framework
. In this talk I will present the first\ncosmological constraints derived
from the analysis of the void size\nfunction\, i.e. the number of cosmic v
oids as a function of their\nradius. These results are obtained from the m
odeling of voids\nidentified in the final BOSS DR12 data set\, adopting a
\nstate-of-the-art methodology to take into account a number of\nobservati
onal effects. I will showcase the constraining power achieved\non the main
parameters of the $\Lambda$CDM and the $w$CDM models. This\nincludes the
first estimate of the parameters $H_0$ and $S_8 \equiv\n\sigma_8\sqrt{\Ome
ga_{\rm m}/0.3}$ derived from cosmic voids\,\nproviding new insights on th
e rising tensions in Cosmology.

DESCRIPTION:Topic: A Characterization of Multiclass Learnability\n\nSpeaker
s: Nataly Brukhim\n\nAffiliation: Princeton University\n\nA seminal result
in learning theory characterizes the PAC learnability\nof binary classes
through the VC dimension. Extending this\ncharacterization to the general
multiclass setting has been open since\nthe late 1980s.\n\nWe resolve this
problem by characterizing multiclass PAC learnability\nthrough the DS dim
ension\, a combinatorial dimension defined by Daniely\nand Shalev-Shwartz
(2014).\n\nThe classical characterization of the binary case boils down to
\nempirical risk minimization. In contrast\, our characterization of the\n
multiclass case involves a variety of algorithmic ideas\; these include\na
natural setting we call list PAC learning. In the list learning\nsetting\
, instead of predicting the label of a given unseen input\, the\ngoal is t
o provide a short list of labels which contains the correct\none with high
probability.\n\nOur second main result concerns the Natarajan dimension\,
which has\nbeen a central candidate for characterizing multiclass learnab
ility.\nThis dimension was introduced by Natarajan (1988) as a barrier for
PAC\nlearning. Whether the Natarajan dimension characterizes PAC\nlearnab
ility in general has been posed as an open question in several\npapers sin
ce. We provide a negative answer: we construct a\nnon-learnable class with
Natarajan dimension one.\n\nFor the construction\, we identify a fundamen
tal connection between\nconcept classes and topology. We crucially rely on
a deep and involved\ngeometric-group-theoretic construction by Januszkiew
icz and\nSwiatkowski. This proof provides another demonstration of the fru
itful\nlinks learning theory has with different areas in mathematics.\n\nJ

DESCRIPTION:Topic: Exponential Mixing and Fractal Uncertainty\n\nSpeakers:
Osama Khalil\n\nAffiliation: University of Illinois Chicago\n\nThe Bowen-R
uelle conjecture predicts that geodesic flows on negatively\ncurved manifo
lds are exponentially mixing with respect to all their\nequilibrium states
. In a breakthrough in '98\, Dolgopyat pioneered a\nmethod rooted in the t
hermodynamic formalism that settled the\nconjecture for flows satisfying c
ertain strong regularity hypotheses.\nSoon after\, Liverani introduced a m
ore intrinsic refinement of\nDolgopyat's method which overcame these regul
arity limitations while\nsimultaneously producing more precise rates of mi
xing\, albeit at the\nprice of being limited to smooth invariant measures.
Despite these\nimportant developments\, the conjecture remains open in ge
neral even\nfor measures of maximal entropy. In this talk\, I will report
on work\nin progress where new ideas leveraging inverse theorems in additi
ve\ncombinatorics are introduced to overcome the limitations in Liverani's
\napproach in a concrete algebraic setting.

exander Migdal\n\nAffiliation: New York University\, Abu Dhabi\n\nThe loop
equation for circulation PDF as functional of the loop\nshape is derived
from the Hopf equation. This equation is\n$\textbf{exactly}$ equivalent to
the Schrödinger equation in loop\nspace\, with viscosity playing the role
of Planck's constant. This\nequivalence\, in principle\, allows direct nu
merical simulation\nof classical turbulence on quantum computers. Topologi
cally stable\ntime-dependent Euler flows\, which we call Kelvinons\, are i
ntroduced.\nThey have a conserved velocity circulation around\n$\textbf{st
ationary}$ loop. Kelvinons are fixed points of the loop\nequation in the W
KB limit of vanishing viscosity at fixed energy\ndissipation\, which corre
sponds to strong turbulence. This makes them\nresponsible for asymptotic P
DF tails of velocity circulation\,\n$\textbf{perfectly matching numerical
simulations}$. Area law and the\nasymptotic scaling law for mean circulati
on at a large area are\nderived from the loop equation. The representation
of the solution of\nthe loop equation in terms of a singular stochastic e
quation for\nmomentum loop trajectory is presented.

mathematics\, as in most professions. Concurrent with this was the\nbirth
of a new field of global or geometric analysis. It was a long\ntime ago\,

However\, in some\nsense\, I believe that I ended up where I am through a

useful to others as well.

DESCRIPTION:Topic: On Furstenberg Systems for Some Aperiodic Multiplicative
Functions\n\nSpeakers: Mariusz Lemanczyk\n\nAffiliation: Nicolaus Coperni
cus University in Toruń\; Member\, School of Mathematics\n\nThe Chowla con
jecture from 1965 predicts that all autocorrelations of\nthe Liouville fun
ction vanish. In fact\, after an adaptation\, the\nChowla conjecture was e
xpected to hold for all aperiodic\nmultiplicative functions with values in
the unit disc (cf. Elliott’s\nconjecture from the 1990s). But in 2015\, M
atom\'aki\, Radziwi\l\l and\nTao gave a counterexample to Elliott’s conjec
ture by constructing\naperiodic multiplicative functions (bounded by 1) fo
r which (already)\nthe Chowla conjecture of order 2 fails. During the talk
I will explain\nhowever that the Chowla conjecture does not disappear ent
irely\, in\nfact\, for Matomäki\, Radziwiłł\, Tao’s functions it holds alo
ng a\nsubsequence. The result is achieved by detecting certain dynamical\n
systems (of algebraic origin)\,\ncalled Furstenberg systems\, obtained by
examining autocorrelations\nalong subsequences. Moreover\, the same techni
que disproves a recent\nconjecture by Frantzikinakis and Host concerning l
ogarithmic\nautocorrelations of multiplicative functions. The talk is base
d on my\njoint work with Alex Gomilko and Thierry de la Rue.

Certain Groups)\n\nSpeakers: Frederick Manners\n\nAffiliation: University
of California\, San Diego\; von Neumann Fellow\, School of Mathematics\n\n
The inverse theorem for the Gowers U^{s+1}-norms has a central place\nin m
odern additive combinatorics\, but all known proofs of it are\ndifficult a
nd most do not give effective bounds.\n\nOver this seminar and the next\,
I will give an outline of a proof\ngiving plausible bounds\, in the case o
f groups Z/NZ where N is a\nlarge prime. Many of the key ideas are presen
t in the cases s=2 and\ns=3\, so I will focus on these for simplicity. Th
e argument splits\ninto an 'algebraic part' which comprises a structure th
eorem for\n'local polynomials'\, and an 'analytic part' which uses this to
deduce\nthe inverse theorem\; the two may be taken somewhat separately.\n
\nI will assume some basic familiarity with the definition of the Gowers\n
norms\, and maybe some basic statements related to the inverse theorem\,\n
but not much else.

: Hao Shen\n\nAffiliation: University of Wisconsin\, Madison\n\nWe will di
scuss stochastic quantization i.e. Langevin dynamic of the\nYang-Mills mod
el on two and three dimensional torus. This is described\nby a Lie algebra
valued stochastic PDE driven by space-time white\nnoise. We construct $(l
ocal)$ solution to this singular SPDE via a\nlimit of smooth regularizatio
ns\; gauge invariance is broken in the\nregularizations but is restored in
the limit. This then defines a\nMarkov process on the space of gauge orbi
ts. We also explain what it\nmeans by an orbit space in this singular sett
ing\, namely we construct\nnew state and orbit spaces on which holonomies
and Wilson loop\nobservables are well-defined. We also compare these const
ructions in\n2D and 3D. These are based on joint work with Ajay Chandra\,
Ilya\nChevyrev\, and Martin Hairer. Time permitting\, we will also briefly
\ndiscuss some progress on Langevin dynamic of lattice Yang-Mills\, based

DESCRIPTION:Topic: Dynamical Degrees of Endomorphisms of Affine Surfaces\n
\nSpeakers: Marc Abboud\n\nAffiliation: University of Rennes\n\nLet $f: \m
athbf C^2 \rightarrow \mathbf \C^2$ be a polynomial\ntransformation. The d
ynamical degree of $f$ is defined as $\lim_n\n(\text{deg} f^n)^{1/n}$\, wh
ere $\text{deg} f^n$ is the degree of the\n$n$-th iterate of $f$. In 2007\
, Favre and Jonsson showed that the\ndynamical degree of any polynomial en
domorphism of $\mathbf C^2$ is a\nquadratic integer. For any affine surfac
e\, there is a definition of\nthe dynamical degree that generalizes the on
e on the affine plane. We\nshow that the result still holds in this case:
the dynamical degree of\nan endomorphism of any complex affine surface is
a quadratic integer.\nIn this talk\, I will give an overview of the recent
results obtained\non dynamical degrees on algebraic varieties and explain
the key tools\nof the proof.

DESCRIPTION:Topic: Non-measurability of the inverse theorem for the Gowers
norms\n\nSpeakers: Terence Tao\n\nAffiliation: Member\, School of Mathemat
ics\n\nOver a high-dimensional vector space $F_p^n $over a fixed finite fi
eld\n$F_p$\, the inverse theorem for the Gowers norm asserts that a bounde
d\nfunction f on this space that has a large Gowers $U^{k+1}$ norm\, must
\nnecessarily correlate with a phase polynomial e(P) of degree $k$ this\nr
esult has a number of applications in additive combinatorics and\nproperty
testing. In the high-characteristic case $p >= k-1$ it is\nknown that th
is phase polynomial e(P) is 'measurable' in the sense\nthat it can be appr
oximated to high accuracy by a function of a\nbounded number of random shi
fts of $f$. In joint work with Asgar\nJamneshan and Or Shalom\, we show t
hat this measurability fails when\np=2 and k=5\, thus functions of large $
U^6(F_2^n)$ norm correlate with\nquintic phases\, but such phases can be n
ecessarily non-measurable.\n\n

DESCRIPTION:Topic: Locally Decodable Codes\n\nSpeakers: Zeev Dvir\n\nAffili
ation: Princeton University\n\nA Locally Decodable Codes (LDC) is an error
correcting code which\nallows the decoding of a single message symbol fro
m a few queries to a\npossibly corrupted encoding. LDCs can be constructe
d\, for example\,\nfrom low degree polynomials over a finite field (with l
ocal decoding\nalong a random line) and also using set systems with restr
icted\nmodular intersections (Matching-Vector codes). Despite the wide\nr
ange of applications in mathematics and theoretical computer science\,\nth
ere are still big gaps in our understanding of LDCs. In particular\,\nwe s
till don't know if there exist LDCs with polynomial encoding\nlength and
constant locallity (even non-explicitly). In this talk I\nwill survey the
known lower and upper bounds on LDCs and outline the\nmain open problems.
We will focus on the linear algebraic (as opposed\nto information theoret
ic) view of LDCs\, allowing for an arbitrary\nunderlying field. This view
leads to problem statements which are\nreminiscent of more traditional li
ne/point incidence problems.

of California\, San Diego\; von Neumann Fellow\, School of Mathematics\n\n
The inverse theorem for the Gowers U^{s+1}-norms has a central place\nin m
odern additive combinatorics\, but all known proofs of it are\ndifficult a
nd most do not give effective bounds.\n\nOver this seminar and the next\,
I will give an outline of a proof\ngiving plausible bounds\, in the case o
f groups Z/NZ where N is a\nlarge prime. Many of the key ideas are presen
t in the cases s=2 and\ns=3\, so I will focus on these for simplicity. Th
e argument splits\ninto an 'algebraic part' which comprises a structure th
eorem for\n'local polynomials'\, and an 'analytic part' which uses this to
deduce\nthe inverse theorem\; the two may be taken somewhat separately.\n
\nI will assume some basic familiarity with the definition of the Gowers\n
norms\, and maybe some basic statements related to the inverse theorem\,\n
but not much else.

Speakers: Semon Kirillovich Rezchikov\n\nAffiliation: Veblen Research Inst
ructor\, School of Mathematics \n\nThe basic invariant of a fixed point of
a Hamiltonian diffeomorphism\,\nbesides its existence (which is implied b
y the proven Arnol'd\nConjecture)\, is the number of eigenvalues of unit n
orm of the\nlinearization of the map at the fixed point. When there are no
such\neigenvalues\, the fixed point is said to be purely hyperbolic\, and
has\ncharacteristically different local dynamics from the contrasting\npa

bifurcations can be used to make periodic points purely\nhyperbolic withou
t appreciably changing Floer-theoretic invariants.\nVia a limiting process
one can approximate Hamiltonian diffeomorphisms\nby hameomorphisms which
behave as if they have only hyperbolic\nperiodic points. We will review th

DESCRIPTION:Topic: A Subpolynomial Approximation Algorithm for Graph Crossi
ng Number in Low-Degree Graphs\n\nSpeakers: Zihan Tan\n\nAffiliation: Rutg
ers University\n\nGraph Crossing Number is a fundamental and extensively s
tudied problem\nwith wide ranging applications. In this problem\, the goal
is to draw\nan input graph $G$ in the plane so as to minimize the number
of\ncrossings between the images of its edges. The problem is notoriously
\ndifficult\, and despite extensive work\, non-trivial approximation\nalgo
rithms are only known for bounded-degree graphs. Even for this\nspecial ca
se\, the best current algorithm achieves a $\tilde\nO(\sqrt{n})$-approxima
tion\, while the best current negative results do\nnot rule out constant-f
actor approximation. All current approximation\nalgorithms for the problem
build on the same paradigm\, which is also\nused in practice: compute a s
et $E'$ of edges (called a planarizing\nset) such that $G\setminus E'$ is
planar\; compute a planar drawing of\n$G\setminus E'$\; then add the drawi
ngs of the edges of E to the\nresulting drawing. Unfortunately\, there are
examples of graphs $G$\, in\nwhich any implementation of this method must
incur $\Omega(OPT^2)$\ncrossings\, where OPT is the value of the optimal
solution. This\nbarrier seems to doom the only currently known approach to
designing\napproximation algorithms for the problem\, and to prevent it f
rom\nyielding a better than $\tilde O(\sqrt{n})$-approximation.\n\nWe prop
ose a new paradigm that allows us to overcome this barrier.\nUsing the new
paradigm\, we reduce the Crossing Number problem to\nCrossing Number with
Rotation System – a variant of the Crossing\nNumber problem\, in which th
e ordering of the edges incident to every\nvertex is fixed as part of inpu
t. We then show a randomized algorithm\nfor this new problem\, that allows
us to obtain a subpolynomial\napproximation for Graph Crossing Number on
low-degree graphs.\n\nThis talk is based on joint work with Julia Chuzhoy
and Sepideh\nMahabadi.

DESCRIPTION:Topic: Non-Rigidity of Horocycle Orbit Closures in Geometricall
y Infinite Surfaces\n\nSpeakers: Or Landesberg\n\nAffiliation: Yale Univer
sity\n\nHorospherical group actions on homogeneous spaces are famously kno
wn\nto be extremely rigid. In finite volume homogeneous spaces\, it is a\n
special case of Ratner’s theorems that all horospherical orbit\nclosures a
re homogeneous. Rigidity further extends in rank-one to\ninfinite volume b
ut geometrically finite spaces. The geometrically\ninfinite setting is far
less understood. We consider\n$\mathbb{Z}$-covers of compact hyperbolic s
urfaces and show that they\nsupport quite exotic horocycle orbit closures.
Surprisingly\, the\ntopology of such orbit closures delicately depends on
the choice of a\nhyperbolic metric on the covered compact surface. In par
ticular\, our\nconstructions provide the first examples of geometrically i
nfinite\nspaces where a complete description of non-trivial horocycle orbi
t\nclosures is known. Based on joint work with James Farre and Yair\nMinsk
y.

DESCRIPTION:Topic: One Curvy Metaphor in Systolic Geometry\n\nSpeakers: Ale
xey Balitskiy\n\nAffiliation: Member\, School of Mathematics \n\nAbstract:
In 2010\, Larry Guth wrote a beautiful essay 'Metaphors in\nsystolic geom
etry'\, where he poetically described several approaches\nto Gromov's cele
brated systolic inequality. A nontrivial special case\nof this inequality
claims that a riemannian n-torus always has a\nnon-contractible loop of le
ngth at most the n-th root of the volume.\nOne of the metaphors draws the
intuition from geometry of scalar\ncurvature\, namely\, the Schoen--Yau me
thod of proving that the n-torus\ndoes not admit a metric of positive scal
ar curvature. I will describe\nthe metaphor and survey some of its recent
applications.

DESCRIPTION:Topic: Convergence of Ergodic Averages Along the Sequence $\Ome
ga(n)$\n\nSpeakers: Kaitlyn Loyd \n\nAffiliation: Northwestern University
\n\nFollowing Birkhoff's proof of the Pointwise Ergodic Theorem\, it has\n
been studied whether convergence still holds along various\nsubsequences.
In 2020\, Bergelson and Richter showed that under the\nadditional assumpti
on of unique ergodicity\, pointwise convergence\nholds along the number th
eoretic sequence $\Omega(n)$\, where\n$\Omega(n)$ denotes the number of pr
ime factors on $n$ counted with\nmultiplicity. In this talk\, we will see
that removing this assumption\,\na pointwise ergodic theorem does not hold
along $\Omega(n)$. Time\npermitting\, we will then study the interplay of
the dynamics with\ncertain number theoretic properties of $\Omega(n)$ to
obtain further\ninformation on the asymptotic behavior of this sequence.

DESCRIPTION:Topic: Smooth Coverings of Space\n\nSpeakers: Oded Regev\n\nAff
iliation: New York University\n\nLet K be a convex body in $R^n$. In some
cases (say when K is a cube)\,\nwe can tile $R^n$ using translates of K. H
owever\, in general (say when\nK is a ball) this is impossible. Neverthele
ss\, we show that one can\nalways cover space 'smoothly' using translates
of K\, in the sense\nthat *each* point in $R^n$ is covered by almost the s
ame small number\nof translates of K (specifically\, (1+-eps)poly(n)). Mor
eover\, we show\nthat this can be achieved by taking the translates to be
the set of\npoints in a random lattice. These results represent substantia
l\nimprovements to bounds of Rogers from the 1950s. The key to the proof\n
are recent breakthroughs due to Dvir\, Dhar\, and others regarding the\ndi
screte Kakeya problem. I will present some history\, applications in\nengi
neering and computer science\, and ideas of the proofs. No\nprerequisites
beyond undergraduate material (measures\, volumes\, vector\nspaces over fi
nite fields) will be assumed.\n\nBased on joint work with Or Ordentlich an

: Nicole Magill\n\nAffiliation: Cornell University\n\nThe four dimensional
ellipsoid embedding function of a toric\nsymplectic manifold M measures w
hen a symplectic ellipsoid embeds into\nM. It generalizes the Gromov width
and ball packing numbers. This\nfunction can have a property called an in
finite staircase\, which\nimplies infinitely many obstructions are relevan

DESCRIPTION:Topic: Overview and Recent Results in Combinatorial Auctions\n
\nSpeakers: Matt Weinberg\n\nAffiliation: Princeton University\n\nIn this
talk\, I'll first give a broad overview of the history of\ncombinatorial a
uctions within TCS\, and then discuss some recent\nresults.\n\nCombinatori
al auctions center around the following problem: There is a\nset M of m it
ems\, and N of n bidders. Each bidder i has a valuation\nfunction $v_i$ fr
om subsets of M to real numbers. The goal is to\npartition the items into
$S_1\,\ldots$\, $S_n$ maximizing $\sum_i\nv_i(S_i)$.\n\nI'll cover 2x2 var
iants of this problem:\n\n * Computational model (brief overview and state
ments of results): n\nparties each separately hold one of the $v_i$\, and
they must use\npoly(n\,m) runtime/queries/etc. to find as good an approxim
ation as\npossible.\n * vs. Communication model (main focus): n parties ea
ch separately\nhold one of the $v_i$ and they must use poly(n\,m) communic
ation to\nfind as good an approximation as possible.\n * Algorithm Design
version (one main focus): all parties honestly\nparticipate in whatever pr
otocol is proposed.\n * Mechanism Design version (also a main focus): The
designer is\nallowed to charge price $p_i$ to agent i\, if desired. Party
i will\nbehave in whatever way they believe maximizes $v_i(S_i) - p_i$. \n
\nA sample of results I'll aim to discuss (at varying levels of detail):\n
\n * Tight bounds on achievable approximation guarantees for\nalgorithms.
\n * The Vickrey-Clarke-Groves auction: a black-box reduction from\nexact
mechanism design to exact algorithm design.\n * Maximal-in-range auctions:
tight bounds on the approximation\nguarantees achievable by 'VCG-like' id
eas.\n * Separations between approximation guarantees achievable by\nalgor
ithms vs. mechanisms.\n\nNo prior background in game theory or combinatori
al auctions will be\nassumed.

DESCRIPTION:Topic: Three 20-min Research Talks\n\nSpeakers: David White\, K
ai Hugtenburg\, Patricia Dietzsch\n\nAffiliation: North Carolina State Uni
versity\; University of Edinburgh\; ETH Zürich\n\nDAVID WHITE (North Carol
ina State University): _Symplectic\nInstanton Homology of Knots and Links
in 3-manifolds_\n\nPowerful homology invariants of knots in 3-manifolds h
ave emerged from\nboth the gauge-theoretic and the symplectic kinds of Flo
er theory: on\nthe gauge-theoretic side is the instanton knot homology of
\nKronheimer-Mrowka\, and on the symplectic the (Heegaard) knot Floer\nhom
ology developed independently by Ozsváth-Szabó and by Rasmussen.\nThese th
eories are conjecturally equivalent\, but a precise connection\nbetween th
e gauge-theoretic and symplectic sides here remains to be\nunderstood. We
describe a construction designed to translate singular\ninstanton knot hom
ology more directly into the symplectic domain\, a\nso-called symplectic i
nstanton knot homology: We define a Lagrangian\nFloer homology invariant o
f knots and links which extends a 3-manifold\ninvariant developed by H. Ho
rton. The construction proceeds by using\nspecialized Heegaard diagrams to
parametrize an intersection of\ntraceless $SU(2)$ character varieties. Th
e latter is in fact an\nintersection of Lagrangians in a symplectic manifo
ld\, giving rise to a\nLagrangian Floer homology. We discuss its relation
to singular\ninstanton knot homology\, as well as the formal properties wh
ich this\nsuggests and methods to prove these properties.\n\nKAI HUGTENBUR
G (University of Edinburgh): _Open Gromov-Witten\nInvariants from the Fuka
ya Category_\n\nEnumerative mirror symmetry is a correspondence between cl
osed\nGromov-Witten invariants of a space X\, and period integrals of a\nf
amily Y. One of the predictions of Homological Mirror Symmetry is\nthat th
e closed Gromov-Witten invariants can be obtained from the\nFukaya categor
y. For Calabi-Yau varieties this has been demonstrated\nby Ganatra-Perutz-
Sheridan. Recently\, enumerative mirror symmetry has\nbeen extended\, by i
ncluding open Gromov-Witten invariants and extended\nperiod integrals. It
is natural to expect that open Gromov-Witten\ninvariants can be obtained f
rom the Fukaya category. In this talk I\nwill outline a construction which
will demonstrate this for certain\nopen Gromov-Witten invariants.\n\nPATR
ICIA DIETZSCH (ETH Zürich) : Lagrangian Hofer Metric and\nBarcodes\n\nFilt
ered Lagrangian Floer homology gives rise to a barcode\nassociated to a pa
ir of Lagrangians. It is well-known that the\nlengths of the finite bars
and the spectral distance are lower bounds\nof the Lagrangian Hofer metric
. In this talk we are interested in a\nreverse inequality. I will explain
an upper bound of the Lagrangian\nHofer distance between equators in the
cylinder in terms of\na weighted sum of the lengths of the finite bars and
the spectral\ndistance.

DESCRIPTION:Topic: Our Galaxy in motion: Ripples\, ridges and spirals in th

\nData from ESA’s Gaia mission is already revolutionizing Galactic\nastron
omy\, providing an unprecedented view of the Solar neighborhood\nand beyon
d. However\, while it provides us a great opportunity to\ntransform our un
derstanding of the Milky Way\, it has also highlighted\nhow far from equil
ibrium our Galaxy is. The spiral pattern in vertical\nposition vs. velocit
y is a signature of our Galaxy’s past\ninteraction with perturbing influen
ces such as merging dwarf galaxies\,\nor internal substructure. We dissect
and analyze these ‘phase\nspirals’\, showing the first discovery of two a
rmed ‘breathing\nspirals’ in the inner disc\, and show how we can leverage
high\nresolution galaxy models and dynamical theory to learn about the\ns
tructure and history of our Galaxy.

DESCRIPTION:Topic: Induced Subgraphs and Tree Decompositions\n\nSpeakers: M
aria Chudnovsky\n\nAffiliation: Princeton University\n\nTree decomposition
s are a powerful tool in both structural graph\ntheory and graph algorithm
s. Many hard problems become tractable if\nthe input graph is known to hav
e a tree decomposition of bounded\n“width”. Exhibiting a particular kind o
f a tree decomposition is\nalso a useful way to describe the structure of
a graph.\n\nTree decompositions have traditionally been used in the contex
t of\nforbidden graph minors\; bringing them into the realm of forbidden\n
induced subgraphs has until recently remained out of reach. Over the\nlast
couple of years we have made significant progress in this\ndirection\, ex
ploring both the classical notion of bounded tree-width\,\nand concepts of
more structural flavor. This talk will survey some of\nthese ideas and re
sults.

DESCRIPTION:Topic: From Embedded Contact Homology to Surface Dynamics\n\nSp
eakers: Jo Nelson\n\nAffiliation: Rice University\; Member\, School of Mat
hematics \n\nI will discuss work in progress with Morgan Weiler on knot fi
ltered\nembedded contact homology (ECH) of open book decompositions of S^3
\nalong T(2\,q) torus knots to deduce information about the dynamics of\ns
ymplectomorphisms of the genus (q-1)/2 pages which are freely\nisotopic to
rotation by 1/(2q) along the boundary. I will explain the\ninterplay betw
een the topology of the open book\, its presentation as\nan orbi-bundle\,
and our computation of the knot filtered ECH chain\ncomplex. I will descr
ibe how knot filtered ECH realizes the\nrelationship between the action an
d linking of Reeb orbits and its\napplication to the study of the Calabi i
nvariant and periodic orbits\nof symplectomorphisms of the pages.

DESCRIPTION:Topic: What have we learned from the Archimedes Palimpsest?\n\n
Speakers: William Noel\, Reviel Netz\n\nAffiliation: Princeton University\
; Stanford University\n\nThe main source for the works of Archimedes is a
medieval manuscript\,\nwritten originally around in 975 CE and then erased
and covered with a\nprayerbook in the year 1229. Briefly studied in 1906\
, the full\ncontents of the manuscripts were finally revealed in recent ye
ars with\nthe aid of modern technologies. Reviel Netz and William Noel\,\n
editors of the works of Archimedes\, lead us through this process of\ndisc
overy and discusses some of the main revelations.\n\nAbout the speakers: W
illiam Noel is the John T. Maltsberger III '55\nAssociate University Libra
rian for Special Collections at Princeton\nUniversity Library. Among his p
ublications is The Archimedes Codex\,\nwith Reviel Netz. Reviel Netz is P
atrick Suppes Professor of\nGreek Mathematics and Astronomy at Stanford Un
iversity. Most recently\,\nhe is the author of A New History of Greek Math
ematics (CUP 2022).

DESCRIPTION:Topic: Connes Embedding Problem\, Kirchberg's Conjecture and Ts
irelson's Problem\n\nSpeakers: Thomas Vidick\n\nAffiliation: California In
stitute of Technology\n\nThe three problems referred to in the title origi
nate in the theory of\nvon Neumann algebras\, C* algebras\, and quantum in
formation theory\nrespectively. Each of them has been a deep long-standing
open problem\nin its respective area. Surprisingly\, the three problems a
re\nequivalent.\n\nRecently we gave a negative answer to all three problem
s by taking an\nunexpected path -- through complexity theory.\n\nThe goal
of these three lectures is to give a flavor of the resolution\nof these th
ree problems\, for a mathematical audience. In the first\nlecture I will i
ntroduce the problems described in the title and\nexplain their equivalenc
e. I will then formulate the approach\, which\ngoes through the careful de
sign of families of linear functionals\nacting on 'quantum correlation spa
ces' and derived from the theory of\nnonlocal games in quantum information
theory.

DESCRIPTION:Topic: From Nonlocal Games to Undecidability\n\nSpeakers: Thoma
s Vidick\n\nAffiliation: California Institute of Technology\n\nIn this lec
ture I will present basic elements of the theory of\nnonlocal games from q
uantum information theory and give some examples.\nI will then introduce t
he idea of 'compressing' the complexity of\nnonlocal games\, and show how
the right form of compression leads to\nundecidability of a natural optimi
zation problem associated with the\ngames. Using the results from the firs
t lecture\, the undecidability\nresult will imply a negative answer to Tsi
relson's problem and its\nequivalent problems in operator algebras.

DESCRIPTION:Topic: Efficient Stability for the Weyl-Heisenberg Group\n\nSpe
akers: Thomas Vidick\n\nAffiliation: California Institute of Technology\n
\nThe question of stability of approximate group homomorphisms was first\n
formulated by Ulam in the 1940s. One of the most famous results in\nthis a
rea is Kazhdan's 1982 result on stability of approximate unitary\nrepresen
tations of an amenable group\, when approximation is measured\nusing the o
perator norm. More recently\, motivated in part by the study\nof group sof
icity and hyperlinearity\, the study of stability has been\npursued for an
increasing variety of notions of approximation.\n\nOne of the key technic
al ingredients in the resolution of Tsirelson's\nproblem is a notion of 'e
fficient' approximate stability\, and its\ndemonstration for a specific fa
mily of finite non-abelian groups\, the\nWeyl-Heisenberg groups. In this (
mostly self-contained) lecture I will\nformulate the efficient stability r
esult\, give some proof ideas\, and\nexplain its use for the compression p
rocedure introduced in the second\nlecture.
