DESCRIPTION:Topic: Probing Pulsar Winds and Particle Acceleration with Spid
er Pulsars\n\nSpeakers: Andrew Sullivan (Stanford University)\n\nRapidly s
pinning millisecond pulsars represent some of the most\nimpressive astroph
ysical machines. A unique class of these objects\nknown as spider pulsars
are found in tight binaries with low mass\ncompanions. The pulsar emission
irradiates the companion star\, driving\noff a massive stellar wind\, whi
ch can collide with the pulsar wind to\nproduce an intrabinary relativisti
c shock. Divided into black widows\nand redbacks\, spider pulsars can have
their intrabinary shocks wrap\naround either the pulsar or the companion.
These shocks represent\nsites of magnetic reconnection and high energy pa
rticle acceleration\nwhich manifests in X-ray emission. In this talk I wil
l discuss how\nspider pulsars represent excellent probes of the pulsar win
d and\nastrophysical shock-driven magnetic reconnection through recent X-r
ay\nanalyses of the intrabinary shock of the massive redback pulsar\nJ2215
+5135 and future polarization measurements enabled by IXPE.

DESCRIPTION:Topic: Supermassive Black Hole Formation in the Early Universe
from Pop III.1 Protostars\n\nSpeakers: Jonathan Tan (Chalmers & U. Virgini
a)\n\nThe origin of supermassive black holes (SMBHs) is a key open questio
n\nfor contemporary astrophysics and cosmology. Here we discuss the\npredi
ctions of a model of SMBH formation from Pop III.1 protostars\,\ni.e.\, me
tal-free stars forming in locally isolated dark matter\nminihalos\, where
dark matter annihilation has a chance to alter the\nstructure of the star
allowing growth to supermassive scales (Banik\,\nTan & Monaco 2019\; Singh
\, Monaco & Tan 2023\; Cammelli et al. 2024).\nThe model predicts that all
SMBHs have already formed by z ~ 25 with a\nspatial distribution that is
initially relatively unclustered. We also\npresent predictions for SMBH oc
cupation fractions\, host galaxy\nproperties\, frequency of binary AGN and
the gravitational wave\nbackground from this SMBH population. These predi
ctions are compared\nto latest results from HST\, JWST and pulsar timing a
rray observations.

DESCRIPTION:Topic: Experimental Studies of Black Holes: Status & Prospects
\n\nSpeakers: Reinhard Genzel\, Max Planck Institute for Extraterrestrial
Physics\n\nAffiliation: Max Planck Institute for Extraterrestrial Physics
\n\nMore than a century ago\, Albert Einstein presented his general theory
\nof gravitation. One of the predictions of this theory is that not only\n
particles and objects with mass\, but also the quanta of light\,\nphotons\
, are tied to the curvature of space-time\, and thus to gravity.\nThere mu
st be a critical mass density\, above which photons cannot\nescape. These
are black holes. It took fifty years before possible\ncandidate objects we
re identified by observational astronomy. Another\nfifty years have passed
\, until we finally can present detailed and\ncredible experimental eviden
ce that black holes of 10 to 1010 times\nthe mass of the Sun exist in the
Universe. Three very different\nexperimental techniques have enabled these
critical experimental\nbreakthroughs. It has become possible to investiga
te the space-time\nstructure in the vicinity of the event horizons of blac
k holes. I will\nsummarize these interferometric techniques\, and discuss
the\nspectacular recent improvements achieved with all three techniques. I
n\nconclusion\, I will sketch where the path of exploration and inquiry\nm
ay lead to in the next decades.

DESCRIPTION:Topic: Cross-Disciplinary Characterization of Exoplanet Atmosph
eres: Observation\, Theory\, and Experiment\n\nSpeakers: Jeehyun Yang (JPL
)\n\nWith the advent of JWST\, the need for detailed chemical and\nphotoch
emical models of exoplanet atmospheres has increased.\nTraditionally\, bui
lding reaction networks required manually tracking\nspecies and reactions\
, a process that is both time-consuming and prone\nto errors\, often limit
ed to specific conditions. We introduce an\nautomated approach using a com
puter-aided chemical reaction network\ngenerator combined with 1D photoche
mical kinetic-transport modeling\,\napplied to various exoplanet atmospher
es from hot Jupiters to\ntemperate sub-Neptunes.\n\nApplying this new fram
ework to temperate sub-Neptunes reveals that the\natmospheric CO2/CH4 rati
o can infer the deep interior H2O/H2 ratio.\nApplying this to recent JWST
observations\, we suggest that K2-18 b\nlikely has an interior with 50% wa
ter enrichment\, indicating\nsignificant ice accretion during its formatio
n. Conversely\, our model\nsuggests that TOI-270 d’s interior is about 25%
water\, consistent\nwith a metallicity exceeding 100x solar metallicity.
Additionally\, our\nmodels identify carbonyl sulfide (OCS) and sulfur diox
ide (SO2) as key\nindicators for temperate sub-Neptunes with at least 10%
water content.\n\nAs a future study\, investigating extensive sulfur (phot
o)chemistry\nwill be crucial. This research should combine ab-initio calcu
lations\nwith experimental measurements\, enabling a cross-disciplinary\nc
haracterization of exoplanet atmospheres.

DESCRIPTION:Topic: Impact of primordial magnetic fields on structure format
ion\n\nSpeakers: Pranjal Ralegankar (SISSA)\n\nPrimordial magnetic fields
(PMFs) offer a simple explanation for the\norigin of galactic magnetic fie
lds as well as of the purportedly\ndetected magnetic fields in cosmic void
s. In the talk\, I discuss how\nPMFs' influence on structure formation can
offer a complementary\nmethod to test for their existence. Specifically\,
I discuss how PMFs\nenhance the matter power spectrum on small scales\, <
Mpc. On scales\nrelevant to galaxies and black holes\, I show that PMFs ca
n\nsignificantly enhance the baryon fraction in halos as well as the\nabun
dance of halos. Next\, I show that on scales below the baryon Jeans\nscale
s\, PMFs can enhance dark matter power spectrum purely by\ngravitational i
nfluence. I conclude by arguing how search for dark\nmatter minihalos can
potentially provide the most sensitive probe for\nPMFs.

DESCRIPTION:Topic: Supermassive Black Holes from AU to Megaparsec: Fundamen
tally New Physics in Accretion Disks\n\nSpeakers: Philip Hopkins\, Institu
te for Advanced Study\n\nAffiliation: Caltech/IAS\n\nSupermassive black ho
les at the centers of galaxies present unsolved\ntheoretical challenges fo
r our understanding of high-energy\nastrophysics\, gravity and gravitation
al waves\, star and galaxy\nformation\, and space plasma physics. For deca
des\, our models have\nstruggled to understand how such “monster” black ho
les could form\nand exist at all. But recent novel multi-physics\, multi-s
cale\nsimulations have led to major breakthroughs. I’ll show how these\nha
ve transformed our understanding of how such black holes could form\,\n“wh
ere they come from\,” and how they grow. With the novel ability\nto follow
the plasma radiation-magneto-thermo-chemistry from scales of\nmegaparsecs
down to horizon scales\, we can now see that many of the\nfoundational as
sumptions of textbook accretion theory are incorrect.\nThe accretion modes
that exist are qualitatively novel\, and this in\nturn completely changes
our intuition about how the “seeds” of\nblack holes grow rapidly in the e
arly Universe\, how they shine as\nquasars and behave in black hole merger
s\, how stars form around black\nholes\, and how their “feedback” in the f
orm of radiation and jets\ninfluences their galactic environments.

DESCRIPTION:Topic: Uncovering the Formation and Evolution of Planetary Syst
ems: The Architecture of Hot Jupiter Systems and the Search for Young Plan
ets\n\nSpeakers: Lizhou Sha\, University of Wisconsin Madison\n\nAffiliati
on: University of Wisconsin Madison\n\nThe demography of young and mature
exoplanets is crucial to\nunderstanding the full picture of planetary syst
em formation and\nevolution. In this talk\, I will highlight two observati
onal approaches\nthat expand the exoplanet demographic census. In the firs
t approach\, I\nfocus on understanding the evolutionary history of hot jup
iters by\nestimating the occurrence rate of their inner companion planets
\nthrough a systematic search of TESS\, Kepler\, and K2 light curves. My\n
search yielded the TOI-2000 system and recovered most known hot\njupiter i
nner companions\, confirming that these systems are indeed\nintrinsically
rare. I will discuss the implication this rarity has on\nthe formation mec
hanisms of hot jupiters. In the second approach\, I\nfocus on searching fo
r young planets in nearby open clusters\, which\nallow us to test hypothes
es on their dynamical evolution and migration\nby comparison to more matur
e systems. Gaia spatio-kinematic data have\nrevealed diffuse and extended
structures known as tidal tails in\nnearby open clusters\, but many of the
se structures lack independent\nverification. My pilot study used TESS to
measure stellar rotation\nperiods in the 120 Myr old nearby open cluster B
lanco 1\, and\, by\ncomparing the gyrochrone sequence of the core and tida
l tail stars\,\nyielded the first independent verification of the reality
and extent\nof its recently discovered tidal tails. The tidal tails more t
han\ndouble the membership of Blanco 1\, pointing to a viable strategy to
\nenhance the local young star census and broaden the search targets for\n
young exoplanets.

ype Ia supernovae (SNe Ia) provide valuable cosmological constraints\ninde
pendent from the Cosmic Microwave Background (CMB) and Baryon\nAcoustic Os

Ia from the Dark Energy Survey (DES) number\naround 1600\, the upcoming Ve

ver about _1 million_ SNe Ia. As we\npursue the tightest SN Ia cosmologica

e SN Ia flux measurements\nand redshift measurements\, both of which are c
rucial for\nhigh-precision cosmology. \n\nIn this talk\, I will give an ov
erview of how investigating\nwavelength-dependent atmospheric effects can
improve both the flux\nmeasurements and the redshift measurements - neithe
r of which have\nbeen utilized in SN Ia cosmology until recently. While co
rrecting for\nsuch effects in our flux measurements will be important for
LSST\,\nwavelength-dependent atmospheric effects can additionally provide
a\nmeasurement of redshifts from _astrometry _that are\nnearly-independent
from conventional photometric redshifts. Combining\nthese _astrometric re
dshifts _with _photometric redshifts _will be\nespecially useful for LSST
since we will not have enough spectroscopic\nresources to follow up the va

efly describe what we can\nachieve with LSST SN Ia observations\, especial
ly by combining them\nwith other cosmological probes in a way that has not

\n\nSpeakers: Jon Trump\n\nAffiliation: University of Connecticut\n\nSuper
massive black holes are a critical ingredient in our Universe.\nThey are t
he most luminous persistent sources in the sky\, in both\nphotons and grav
itational waves\, and they play an essential role in\nthe formation and gr
owth of galaxies. My research seeks a\ncomprehensive census of black holes
using two complementary\napproaches. First\, I will show how pioneering n
ew SDSS time-domain\nspectroscopy enables a census of black hole mass\, gr
owth rate\, and\nspin over most of cosmic time. I will also present the fo
recast for\nRubin/LSST discovery of binary black holes: the electromagneti
c\ncounterparts to gravitational echoes seen in pulsar timing and\n(eventu
ally) LISA. Meanwhile the first year of JWST observations has\nrevealed a
surprisingly active early Universe\, with a large number of\nmassive black
holes identified in z>5 galaxies. This implies a\nsignificant population
of heavy black hole seeds and suggests that\naccreting black holes play a
significant role in reionizing the\nUniverse. The next generation of time-
domain\, space-telescope\, and\nmulti-messenger experiments make it a trul

DESCRIPTION:Topic: Spectral Gap of the Laplacian for Random Hyperbolic Surf
aces\n\nSpeakers: Nalini Anantharaman\, Collège de France\n\nAlthough ther
e are several ways to ''choose a compact hyperbolic\nsurface at random''\,
putting the Weil-Petersson probability measure on\nthe moduli space of hy
perbolic surfaces of a given topology is\ncertainly the most natural. The
work of M. Mirzakhani has made\npossible the study of this probabilistic m
odel\, providing exact\nformulas for certain integrals\, as well as their
asymptotic behaviour\nin the limit of large genus.\n\nI will be interested
in the spectral gap $\lambda_1$ of the laplacian\nfor a random compact hy
perbolic surface\, in the limit of large genus\n$g$ : in joint work with L
aura Monk\, we show that asymptotically\nalmost surely\, $\lambda_1 > 1/4
-\epsilon$ for any $\epsilon >0$.\n\nThe proof relies on the trace method.
We use asymptotic expansions in\npowers of $g^{-1}$ for volume functions
giving the distribution of the\nlength spectrum\, and prove that the coeff
icients possess the\n``Friedman-Ramanujan property' (a notion introduced b
y J. Friedman in\nhis proof of the Alon conjecture for random regular grap
hs).

DESCRIPTION:Topic: Spectral Gap of the Laplacian for Random Hyperbolic Surf
aces \n\nSpeakers: Nalini Anantharaman\, Collège de France\n\nAlthough the
re are several ways to ''choose a compact hyperbolic\nsurface at random''\
, putting the Weil-Petersson probability measure on\nthe moduli space of h
yperbolic surfaces of a given topology is\ncertainly the most natural. The
work of M. Mirzakhani has made\npossible the study of this probabilistic
model\, providing exact\nformulas for certain integrals\, as well as their
asymptotic behaviour\nin the limit of large genus.\n\nI will be intereste
d in the spectral gap $\lambda_1$ of the laplacian\nfor a random compact h
yperbolic surface\, in the limit of large genus\n$g$ : in joint work with
Laura Monk\, we show that asymptotically\nalmost surely\, $\lambda_1 > 1/4
-\epsilon$ for any $\epsilon >0$.\n\nThe proof relies on the trace method
. We use asymptotic expansions in\npowers of $g^{-1}$ for volume functions
giving the distribution of the\nlength spectrum\, and prove that the coef
ficients possess the\n``Friedman-Ramanujan property' (a notion introduced
by J. Friedman in\nhis proof of the Alon conjecture for random regular gra
phs).

DESCRIPTION:Topic: Six years of Parker Solar Probe: The emerging scenario o
f solar wind energization and heating\n\nSpeakers: Stuart Bale\n\nAffiliat
ion: University of California\, Berkeley\n\nThe NASA Parker Solar Probe (P
SP) mission was launched in 2018 and has\nmade 20 orbits of the Sun with p
erihelion altitudes down to 10.3 solar\nradii. After a Venus Gravity Assis
t in November of this year\,\nperihelion will reach 8.8 solar radii above
the photosphere. An\nincreasingly plausible picture is emerging of where t
he solar wind\noriginates\, how it is initially energized\, and the plasma
physics of\nthe extended wind heating process. In this scenario\, the win
d\noriginates by magnetic reconnection at intense bundles of field energy
\nassociated with the supergranulation convection cells. The emerging\nwin
d generates Alfven waves\, by the reconnection process\, shearing\ninstabi
lities\, or phase speed gradients. These Alfven waves grow to\nlarge ampli
tude dB/B~1 by a combination of plasma expansion and\nconservation of wave
action. The large nonlinear Alfven waves generate\nsmall scale turbulence
that results in plasma (ion cyclotron) heating\,\nwhich provides the ther
mal energy to counteract the cooling of\nexpansion. I will review some of
the key PSP results that underpin\nthis scenario and I will show a surpris
ing result suggesting that the\nradial evolution of these nonlinear Alfven
waves generates significant\nmagnetic field in a dynamo-like process.

DESCRIPTION:Topic: Concentration on HDX: Derandomization Beyond Chernoff\n
\nSpeakers: Max Hopkins\, Institute for Advanced Study\n\nChernoff's bound
states that for any $A \subset [N]$ the probability\na random $k$-tuple $
s \in {[N] \choose k}$ correctly `samples'\n$A$ (i.e. that the density of
$A$ in $s$ is close to its mean)\ndecays exponentially in the dimension $k
$. In 1987\, Ajtai\, Komlos\,\nand Szemeredi proved the 'Expander-Chernoff
Theorem'\, a\npowerful _derandomization _of Chernoff's bound stating that
one can\nreplace ${[N] \choose k}$ with the significantly sparser\nfamily
$X_G(k) \subsetneq {[N] \choose k}$ of length-$k$ paths on\nan expander g
raph $G$ while maintaining essentially the same\nconcentration. Their resu
lt\, which allows amplification without\nsignificant blow-up in size or ra
ndomness\, has since become a\nmainstay in theoretical computer science wi
th breakthrough\napplications in derandomization\, coding\, pseudorandomne
ss\,\ncryptography\, and complexity.\n\nOne natural way to view AKS is to
say Expander-Walks are pseudorandom\nwith respect to functions of their ve
rtices\, or against 'degree 1'\nfunctions. In modern complexity\, especial
ly in the context of hardness\namplification and PCPs\, we often need conc
entration against _higher\ndegree _functions\, e.g. functions of edges or
triples. Unfortunately\,\ndue to their inherent _low-dimensionality_\, wal
ks on expanders are\nnot pseudorandom even at degree 2\, and the construct
ion of such a\nde-randomized object has remained largely open. \n\nIn 2017
Dinur and Kaufman offered a partial resolution to this\nquestion in the i
ntroduction of (spectral) _high dimensional\nexpanders\,_ a derandomized f
amily satisfying Chebyshev-type (inverse\npolynomial) concentration for hi
gher degree functions. Their\nwork led to breakthrough applications in agr
eement testing and PCPs\n(Bafna and Minzer 2024)\, but left an exponential
gap with known bounds\nfor the complete hypergraph ${[N] \choose k}$ need
ed for other\napplications. In this talk\, we close this gap and prove (st
rong\nenough) HDX indeed match the concentration of ${[N] \choose k}$. Tim
e\nwilling\, we will additionally discuss the relation of these bounds to
\nagreement testing and a powerful analytic inequality called reverse\nhyp
ercontractivity.\n\nBased on joint work [https://arxiv.org/abs/2404.10961v

CT: I will naively analyze the Regge trajectory of the\nleading-twist oper
ators in the critical O(N) model to leading order in\n1/N. The anomalous d
imensions of these operators develop simple poles\nin the spin J\, prevent
ing one from naively continuing them\nanalytically across these singularit
ies in J. These poles correspond\nto mixings between different operators\,
including nonlocal ones. I\nwill show that the leading singularity can be
resolved by properly\nrenormalizing the IR divergences of light-ray opera
tors\, and this\nresolution gives the Regge intercept for the leading pome
ron. I will\nalso briefly comment on the mixing into the BFKL-type horizon
tal\ntrajectory and raise some interesting questions regarding the Regge\n
trajectory in the critical O(N) model.

DESCRIPTION:Topic: What We Think We Know About Lyman Alpha Emitting Galaxie
s\n\nSpeakers: Eric Gawiser\, Institute for Advanced Study\n\nAffiliation:
Rutgers University\n\nThe following statements are often made about high-
redshift Lyman\nAlpha Emitting (LAE) galaxies: \n\n1. They are young\, l
ow-dust galaxies undergoing initial bursts of\nstar formation. \n\n2. Du
e to resonant scattering\, Lyman alpha photons experience much\nhigher dus
t extinction than UV continuum radiation. \n\n3. LAEs lie on the same co
rrelation between star formation rate and\nstellar mass as other star-form
ing galaxies at the same redshift. \n\n4. A galaxy whose observed Lyman
alpha emission has rest-frame\nequivalent width >240 Angstroms possesses a
top-heavy IMF\, likely from\nPopulation III stars. \n\n5. LAEs at z<6 a
re faithful tracers of the large-scale structure and\ncan therefore be use
d to probe cosmology. \n\n6. The topology of reionization can be probed v
ia the effect of\nionized bubbles on LAE clustering.\n\n7. The high Lyman
alpha escape fractions of LAEs imply sufficiently\nhigh Lyman continuum e
scape fractions for similar galaxies at z>7 to\nreionize the universe. \n
\nI will assess the validity of each of these statements\, arguing that\nn
one have yet been proven and that each requires some caveats. I\nwill the
n describe how we can test each (amended) statement using\nongoing survey
s and simulations.

DESCRIPTION:Topic: Pushing the S-matrix Bootstrap\n\nSpeakers: Jan Albert\,
Princeton University\n\nABSTRACT: First introduced in the 60s\, positivit
y bounds for\nS-matrices have undergone a revival in the past few years\,
with\nsystematic implementations that improve by the day. Among the recent
\nresults are sharp bounds on the EFTs of various gauge and\ngravitational
theories. A common feature of the resulting exclusion\nregions\, however\
, is that they tend to be saturated by S-matrices that\nare physically not
that interesting. In this talk\, I will discuss what\nassumptions can tak
e us beyond this paradigm. After a brief recap on\nthe subject\, I will de
scribe how positivity bounds define a bootstrap\nproblem closely analogous
to the well-known conformal bootstrap. This\nanalogy will motivate new as
sumptions\, which we will then apply to\nlarge N confining gauge theories
and to weakly-coupled completions of\n10d supergravity. I will explain how
this refinement leads to peculiar\nsolutions which are\, respectively\, s
urprisingly close to real-world\nQCD and tree-level string theory.

DESCRIPTION:Topic: Sorting Using Partial Information\n\nSpeakers: Robert Ta
rjan\, Princeton University\n\nWe consider the problem of sorting a set of
items having an unknown\ntotal order by doing binary comparisons of the i
tems\, given the\noutcomes of some pre-existing comparisons. We present a
simple new\nalgorithm with a running time of O(m + n + log T)\, where n\,
m\, and T\nare the number of items\, the number of pre-existing comparison
s\, and\nthe number of total orders consistent with the outcomes of the\np
re-existing comparisons\, respectively. The algorithm does O(log T)\ncompa
risons. Both our time and comparison bounds are best possible up\nto const
ant factors\, thus resolving a problem that has been open since\n1978. Our
algorithm combines two classic algorithms: topological sort\nand heapsort
with the right kind of heap.\n\nThis is joint work with Bernhard Haeupler
\, Richard Hladík\, John\nlacono\, Vaclay Rozhoi\, and Jakub Tětek.

DESCRIPTION:Topic: Untangling the Cosmic Web: Correlations between small-sc
ale clustering and large-scale structure\n\nSpeakers: Claire Lamman\n\nAff
iliation: Harvard University\, CfA\n\nGravitational forces from the larges
t structures in the Universe leave\na detectable imprint on galaxies and t
heir local environment. This can\nmanifest as the 'Intrinsic Alignment' of
galaxy orientations to the\nlarge-scale tidal field\, although measuring
these correlations is\nlimited by the imaging of galaxy shapes and is not
observed in blue or\nfaint galaxies. I will present a new approach: tracin
g the tidal field\nwith small groups of galaxies\, or 'multiplets'. Multip
lets mostly\nconsist of 2-4 galaxies within 1 Mpc/h of each other\, and we
measure\ntheir orientations relative to the galaxy-traced tidal field. Us
ing\nspectroscopic redshfits from the DESI Y1 survey\, we detect intrinsic
\nalignment out to projected separations of 100 Mpc/h and beyond\nredshift
1. We find a simillar signal regardless of galaxy luminosity\nor color\,
which could make multiplet alignment a useful tool for\nmapping the direct
ion of the tidal field. Our detection demonstrates\nthat galaxy clustering
in the non-linear regime of structure formation\npreserves an interpretab
le memory of the large-scale tidal field.

DESCRIPTION:Topic: A Scattering Theory for Linearised Gravity on the Exteri
or of the Schwarzschild Black Hole\n\nSpeakers: Hamed Masaood\, Princeton
University\n\nABSTRACT: I will talk about the scattering problem in genera
l\nrelativity\, and present a construction of a scattering theory\nresolvi
ng the problem for the linearised Einstein equations in a\ndouble null gau
ge against a Schwarzschild background. This is done by\nfirst constructing
a scattering theory for the gauge invariant\ncomponents of the linearised
system via the spin $\pm2$ Teukolsky\nequations\, and this is the subject
of the first part of the talk. I\nwill then discuss how this theory can b
e extended to the full system.\nKey to this step is the identification of
suitable asymptotic gauge\nconditions on scattering data. Here\, a Bondi-a
dapted double null gauge\nis shown to provide the necessary gauge rigidity
\, in a manner that\nenables the identification of Hilbert-space isomorphi
sm between finite\nenergy scattering data and a suitable space of finite e
nergy Cauchy\ndata. In particular\, the gauge conditions made on scatterin
g data will\nallow for a global treatment of the BMS group\, and the memor
y effect\nat past and future null infinity.

DESCRIPTION:Topic: Thermal Sunyaev-Zeldovich Effect in the Circumgalactic M
edium of L* Galaxies\n\nSpeakers: Amiel Sternberg\, Flatiron Institute and
Tel Aviv University\n\nI will describe our recent paper Oren+ 2024 arXiv2
403.09476 in which\nwe analyze recent observations of the the thermal Suny
aev-Zeldovich\n(tSZ) effect arising in the circumgalactic medium (CGM) of
L*\ngalaxies. We make use of analytic models and simulations. The\nobserv
ations imply steep radial electron pressure profiles\, with\nbaryon fract
ions exceeding half the cosmic values expected for the\ndark-matter halos.
An isentropic equation of state is favored over an\nisothermal CGM gas di
stribution. The tSZ signals are broadly\nconsistent with hot-gas high-ioni
zation metal absorbers such as OVI.\nThe Illustris TNG100 simulation under
predicts the observed tSZ\nstrengths suggesting that the simulation is eje
cting too much gas from\nthe galaxy halos.

DESCRIPTION:Topic: A New Approach to Strong Convergence\n\nSpeakers: Ramon
Van Handel\, Institute for Advanced Study\n\nIt was conjectured by Alon in
the 1980s that random d-regular graphs\nhave the largest possible spectra
l gap (up to negligible error) among\nall d-regular graphs. This conjectur
e was proved by Friedman in 2004\nin major tour de force. In recent years\
, deep generalizations of\nFriedman's theorem\, such as strong convergence
of random permutation\nmatrices due to Bordenave and Collins\, have playe
d a central role in a\nseries of breakthrough results on random graphs\, g
eometry\, and\noperator algebras.\n\nIn this talk\, I will discuss a surpr
isingly simple new approach to\nsuch results that is almost entirely based
on soft arguments. This\napproach makes it possible to address previously
inaccessible\nquestions: for example\, it enables a sharp understanding o
f the large\ndeviation probabilities in Friedman's theorem\, and establish
es strong\nconvergence of very high-dimensional representations of the sym
metric\nand classical groups. I will aim to explain some of these results
and\nthe basic ideas on which they are based. \n\nJoint work with Chen\, G
arza-Vargas\, and Tropp.

in how self-dual metrics (which correspond to spacetimes\ncontaining only

on of said spacetime\, we can give a\nfirst principles proof of the NSVW t
ree formula for graviton MHV\nscattering in Einstein gravity. Time permitt

the action of the\nso-called Lw1+infinity algebra on metrics in self dual
gravity.\n\n

DESCRIPTION:Topic: The Mysterious Kronecker Coefficients\n\nSpeakers: Greta
Panova\, Institute for Advanced Study\n\nThe Kronecker coefficients of th
e Symmetric group $S_n$ are the\nmultiplicities of an irreducible $S_n$ re
presentation in the tensor\nproduct of two other irreducibles. They were i
ntroduced in 1938 by\nMurnaghan and generalize the beloved Littlewood-Rich
ardson\ncoefficients of the General Linear group. 86 years later still ver
y\nlittle is known about them and they are subject of some of the major\no
pen problems in Algebraic Combinatorics. They also appear within\nGeometri
c Complexity theory\, in the quest for multiplicity\nobstructions to show
computational lower bounds for VP versus VNP. In\nthis talk\, we will give
an overview of the problems and discuss some\nrecent developments on posi
tivity\, asymptotics and computational\ncomplexity of the Kronecker coeffi
cients and the reduced Kronecker\ncoefficients.\n\nWe will feature results
from joint works with Christian Ikenmeyer\,\nIgor Pak and Damir Yeliussiz
ov.

stitute\n\nI’ll discuss an old technique called intensity interferometry\,
\npioneered by Hanbury Brown and Twiss (HBT) that allows us to achieve\nsu
b-microarcsecond angular resolution using ordinary ground-based\noptical t
elescopes observing visible light. This technique is best\nsuited for com

Shouwu Zhang\nabout a generic positivity of the Beilinson-Bloch height fo
r the\nGross-Schoen and Ceresa cycles of curves of genus at least 3. We al
so\nconstruct a Zariski open dense subset U of the moduli space of curves\
,\nsuch that the canonical Gross-Schoen cycle of any curve parametrized\nb
y a transcendental point outside U is non-torsion (same for the\ncanonical
Ceresa cycle). Some ingredients in our proof\, which I will\nexplain in t
his talk\, are Griffiths’ normal functions\, Hain’s\nmetrized biextension
line bundles and the Betti form\, the Ax-Schanuel\ntheorem for variations
of mixed Hodge structures\, and adelic line\nbundles over quasi-projective
varieties.

DESCRIPTION:Topic: Non-Invertible Symmetries\, Boundary Conditions\, and To

tudy\n\nABSTRACT: In recent years\, there have been various activities try
ing\nto better understand the interplay between non-invertible global\nsym
metries and boundary conditions in quantum field theories\, with\napplicat
ions ranging from scattering of solitons to symmetry-resolved\nentanglemen
t entropies. In this talk\, I will focus on 1+1d conformal\nfield theories
\, and start by reviewing some of the fundamental\nproperties of topologic
al line defects that generate global\nsymmetries. I will then discuss how
the algebra of symmetry operators\nis modified in the presence of conforma
l boundary conditions.\nUniversal kinematic aspects of this symmetry algeb
ra\, such as its\nrepresentation theory\, are neatly captured by a 2+1d to
pological field\ntheory defined on manifolds with corners\, which I will e
xplain.\n\nBased on https://arxiv.org/pdf/2409.02159 and\nhttps://arxiv.or

DESCRIPTION:Topic: Subgroup Tests and the Aldous--Lyons Conjecture\n\nSpeak
ers: Michael Chapman\, New York University\n\nA common theme in mathematic
s is that limits of finite objects are\nwell behaved. This allows one to p
rove many theorems about FINITELY\nAPPROXIMABLE objects\, while leaving th
e general case open ---\nexamples for this are Gottschalk's conjecture\, K
aplansky's direct\nfiniteness conjecture\, and many more. When the topolog
y of the space\nis somewhat coarse\, it becomes very hard to decide\nwheth
er EVERY object is approximable by finite ones\, or whether\nthere exist N
ON-APPROXIMABLE objects. Some of the more famous\nproblems in various fiel
ds of mathematics can be framed this way\; this\nincludes Connes' embeddin
g problem (CEP) in functional analysis\, the\nAldous--Lyons conjecture in
probability theory\, the soficity problem\nof Gromov--Weiss in group theor
y\, and more. \n\nIn 2019\, Ji--Natarajan--Vidick--Wright--Yuen resolved C
EP in the\nnegative\, namely\, they showed that there are non-approximable
\ncharacters of the free group. The amazing thing about their result is\nt
hat it is deduced from COMPLEXITY THEORY\, and specifically from\nundecida
bility in certain (quantum) interactive proof systems.\nInspired by their
work\, we suggest a novel interactive proof system\nwhich is related to th
e Aldous--Lyons conjecture in the following way:\nIf the Aldous--Lyons con
jecture was true\, then every language in this\ninteractive proof system i
s decidable. A key concept we introduce for\nthis purpose is that of a Sub
group Test\, which is our analogue of a\nNon-local Game. By providing a re
duction from the Halting Problem to\nthis new proof system\, we refute the
Aldous-Lyons conjecture.\n\nIn this first talk we introduce the main conc
epts\, motivate the\nconjecture and give a high level description of the p
roof\nstrategy. NO SPECIAL MATHEMATICAL BACKGROUND WILL BE ASSUMED.\n\nThi
s talk is based on a joint work with Lewis Bowen\, Alex Lubotzky and\nThom
as Vidick.

ABSTRACT: The Anti-de-Sitter/Condensed Matter Theory (AdS/CMT)\ncorrespond
ence has attracted significant attention within high-energy\nphysics\, par
ticularly in the study of holographic superconductors\,\nwhich are modeled
as asymptotically Anti-de-Sitter (AdS) hairy black\nholes. In this talk\,
I will present recent mathematical advancements\nin the construction of a
symptotically AdS hairy black holes and the\nanalysis of their interior st
ructure. If time permits\, I will explain\nhow these mathematical results
can be adapted to gain insights into\nthe interiors of asymptotically flat
black holes as well.

DESCRIPTION:Topic: Holographic Dual of Crosscap CFT and Emergent de Sitter
Features\n\nSpeakers: Zixia Wei\, Harvard University\n\nABSTRACT: I propos
e a bottom-up correspondence between a CFT defined\non 2D non-orientable m
anifolds\, such as the real projective plane\n(RP2) and the Klein bottle (
K2)\, and AdS3 Einstein gravity with dS2\nend-of-the-world branes. In this
correspondence\, a global dS2\nend-of-the-world brane (a quotient by Z2)
is described by the unitary\ntime evolution of a crosscap state in the CFT
\, post-selected on the\nCFT ground state.\nFrom the boundary perspective\
, certain 2D non-orientable manifolds\,\nsuch as RP2\, do not admit a bulk
\, making it nontrivial to understand\nhow the bulk is filled by an AdS3 d
ual. From the gravity perspective\,\nwhile AdS3 with a dS2 end-of-the-worl
d brane is expected to shed light\non dS2 quantum gravity\, its CFT dual h
as not yet been identified. In\ncontrast\, AdS3 with an AdS2 end-of-the-wo
rld brane has long been known\nto be dual to a 2D boundary CFT\, a duality
that has played an\nimportant role in understanding quantum aspects of Ad
S2 gravity\,\nincluding the information paradox.\n\nTo establish the corre
spondence\, we compute the holographic RP2\npartition function (or p-funct
ion)\, the one-point function\, and the\nKlein bottle partition function\,
demonstrating that they successfully\nreproduce the CFT results. If time
permits\, I will also prove that the\nholographic p-function is monotonic
under a holographic RG flow\, whose\nCFT dual remains to be determined.

DESCRIPTION:Topic: Subgroup Tests and Tailored Non-local Games\n\nSpeakers:
Michael Chapman\, New York University\n\nIn the previous talk\, we define
d Subgroup Tests and the interactive\nproof system induced by them. In add
ition\, we showed that if the\nAldous--Lyons conjecture was true\, then th
is interactive proof system\ncontains only decidable languages. In this ta
lk\, we describe why the\nHalting Problem can be decided in our interactiv
e proof system\, which\nin turn refutes the Aldous--Lyons conjecture. This
is done in two\nsteps: The first relates Subgroup Test to a new subclass
of non-local\ngames which we term Tailored Games. The second shows that th
e\ntechniques of MIP*=RE can be refined so that all the games in it are\nt
ailored\, or in acronym fashion\, that Tailored-MIP*=RE.\n\nThis talk is b
ased on a joint work with Lewis Bowen\, Alex Lubotzky and\nThomas Vidick.

arieties\n\nSpeakers: Pavel Kurasov\, Stockholm University\n\nFourier Quas
icrystals (FQ) are defined as crystalline measures $$ \mu\n= \sum_{\lambda
\in \Lambda} a_\lambda \delta_\lambda\, \quad \hat{\mu}\n= \sum_{s \in S}
b_s \delta_s\, $$ so that not only $ \mu $ (and hence\n$ \hat{\mu} $) are
tempered distributions\, but also $$ |\mu| : =\n\sum_{\lambda \in \Lambda
} |a_\lambda| \delta_\lambda \quad \mbox{and}\n\quad |\hat{\mu}| := \sum_{
s \in S} |b_s| \delta_s\, $$ are tempered. \n\nOne-dimensional FQs with po
sitive integer weights (that is $a_\lambda\n\in \mathbb N $) can be descri
bed using stable Lee-Yang polynomials\,\nas was proven in a joint work wit
h Peter Sarnak. Multidimensional\nFourier quasicrystals are discussed in t
he current talk. It is shown\nthat a rather general family of FQs in $ \ma
thbb R^d $ with positive\ninteger weights can be constructed using co-dime
nsion $d$ Lee-Yang\nvarieties in $ \mathbb C^n\, \, n > d.$ These complex
algebraic\nvarieties are symmetric and avoid certain regions in $ \mathbb
C^n $\,\nthus generalising zero sets of Lee-Yang polynomials. \n\nIt is sh
own that such FQs can be supported by Delaunay almost periodic\nsets and a
re genuinely multidimensional in the sense that their\nrestriction to any
one-dimensional subspace is not given by a\none-dimensional FQ. Connection
s to alternative recent approaches by\nYves Meyer\, Lawton-Tsikh and de Co
urcy-Ireland-K. are clarified. Is it\npossible that our construction gives
all multidimensional FQs with\npositive integer masses?\n\nThis is joint
work with L. Alon\, M. Kummer\, and C. Vinzant\n(arXiv:2407.11184).

DESCRIPTION:Topic: Gravitational atoms and black hole binaries\n\nSpeakers:
Giovanni Maria Tomaselli\, Institute for Advanced Study\n\nSuperradiant i
nstabilities may create clouds of ultralight bosons\naround rotating black
holes\, forming so-called 'gravitational atoms'.\nIn this talk\, I will r
eview a series of papers that study the effects\nof a binary companion’s p
resence. The companion can induce\ntransitions between bound states of the
cloud (resonances)\, as well as\ntransitions from bound to unbound states
(ionization). These processes\nbackreact on the binary’s dynamics and lea
ve characteristic imprints\non the emitted gravitational waves (GWs)\, pro
viding direct information\nabout the mass of the boson and the state of th
e cloud. However\, some\nof the resonances may destroy the cloud before th
e binary enters the\nfrequency band of future gravitational wave detectors
. This\ndestruction leaves a mark on the binary’s eccentricity and\ninclin
ation\, which can be identified through a statistical analysis of\na popul
ation of binary black holes.

DESCRIPTION:Topic: Gravity as a Mesoscopic System\n\nSpeakers: Pietro Pelli
coni\, University of Geneva / Princeton University\n\nABSTRACT: We employ
a probabilistic mesoscopic description to draw\nconceptual and quantitativ
e analogies between Brownian motion and\nlate-time fluctuations of thermal
correlation functions in generic\nchaotic systems respecting ETH. We appl
y this formalism to the case of\nsemiclassical gravity in AdS3\, showing t
hat wormhole contributions can\nbe naturally identified as moments of stoc
hastic processes. Adopting\nthis perspective shows that semiclassical grav
ity in AdS can be\nnaturally interpreted as a mesoscopic description of qu
antum gravity\,\nand a mesoscopic holographic duality can be framed as a\n
moment-vs-probability-distribution duality.

DESCRIPTION:Topic: Decoding the Mysteries of Fast Radio Bursts: Diverse Ori
gins and Future Prospects\n\nSpeakers: Mohit Bhardwaj\, Carnegie Mellon Un
iversity\n\nFast radio bursts (FRBs) are among the most intriguing mysteri
es in\nmodern astronomy\, with their origins remaining elusive even 17 yea
rs\nafter their discovery. Theories explaining FRBs span a wide range\,\nf
rom catastrophic events to more persistent\, non-cataclysmic origins.\nIn
recent years\, magnetar-based models have gained traction\, yet\nquestions
persist about whether most FRBs are the result of rapid\,\npost-supernova
processes or if they emerge from recycled compact\nobjects over longer ti
mescales.\n\nRecent findings support young progenitor models\, underpinned
by host\ngalaxy demographics and the recognition of significant selection
\nbiases. However\, the detection of FRBs in green-valley and quiescent\ng
alaxies (albeit from a small sample size) suggests that a more\ncomplex an
d diverse range of formation pathways may be at play. This\nraises critica
l questions: Can core-collapse supernovae alone account\nfor the observed
host galaxy distribution? Do the data indicate\nmultiple formation channel
s within the prompt category\, beyond just\nmassive star explosions? And h
ow do selection biases influence our\nunderstanding of these mechanisms?\n
\nIn this talk\, I will explore these questions through the lens of\nobser
vations from over two dozen well-localized FRBs in the local\nUniverse. I
will present new insights into the potential origins of\nthese enigmatic b
ursts\, emphasising the role of host galaxy\nenvironments and the influenc
e of selection effects. Finally\, I will\ndiscuss what the next few years
may hold for FRB research\,\nhighlighting how upcoming observations could
bridge critical gaps in\nour understanding of stellar evolution and the li
fecycle of compact\nobjects.

DESCRIPTION:Topic: Representations on the Cohomology of the Moduli Space of
Pointed Rational Curves\n\nSpeakers: Donggun Lee\, Institute for Basic Sc
ience\, Center for Complex Geometry\n\nThe moduli space of pointed rationa
l curves has a natural action of\nthe symmetric group permuting the marked
points. In this talk\, we\nwill present a combinatorial formula for the
induced representation on\nthe cohomology of the moduli space\, along with
a recursive algorithm\nderived from this formula. These results arise fro
m wall crossing\nphenomena among birational models of the moduli space\, g
overned by\nHassett’s theory of weighted stable curves and Choi-Kiem’s the
ory\nof delta-stability of quasimaps.\n\nThese results enable us to study
positivity and log-concavity of the\nrepresentation. Specifically\, we wil
l provide partial affirmative\nanswers to the question of whether the repr
esentation is permutation\nrepresentation in each degree. We will also pre
sent explicit inductive\nand asymptotic formulas for the multiplicity of t
he trivial\nrepresentation and confirm its asymptotic log-concavity. If ti
me\npermits\, we will also discuss the multiplicities of other irreducible
\nrepresentations as well. This talk is based on joint works with Jinwon\n
Choi and Young-Hoon Kiem.

ti-variate residues on Grassmannians $G(k\,n)$ and moduli spaces\n$M_{0\,n
}$ are ubiquitous in the study of scattering amplitudes\; they\nprovide a
powerful and essential tool. Amenable theories include the\nbiadjoint scal

ill review a relation between such multi-variate residues\nand the real tr
opical Grassmannian\, i.e. the set of valuated matroids\nwhich are realiza
ble over the real numbers. In this way\, a physical\nproblem becomes a que

DESCRIPTION:Topic: Tropical Vector Bundles and Matroids\n\nSpeakers: Kiumar
s Kaveh\, University of Pittsburgh\n\nAbstract: A toric vector bundle is a
torus equivariant vector bundle\non a toric variety.\n\nWe begin by recal
ling the classification of toric vector bundles due\nto Klyachko. The Klya
chko data of a toric vector bundle can be\ninterpreted as a 'piecewise lin
ear map' from the fan of toric variety\nto the space of valuations on a ve
ctor space. Motivated by this\, we\ndefine the notion of a 'piecewise line
ar map' from a fan to the\nBergman fan of a matroid. We call this combinat
orial object a\n'tropical toric vector bundle' (alternatively it can be ca
lled a\n'toric matroid bundle'). We define equivariant K-theory and\nchara
cteristic classes of these bundles. As a particular case\, we see\nthat an
y matroid comes with tautological tropical toric vector bundles\nover the
permutahedral toric variety and the corresponding equivariant\nK-classes a
nd Chern classes recover the tautological classes of\nmatroids constructed
in the recent work of Berget-Eur-Spink-Tseng. In\nanalogy with toric vect
or bundles\, one can define sheaf of sections\nand Euler characteristic as
well as positivity notions such as global\ngeneration\, ampleness and nef
ness for tropical toric vector bundles\nand prove a kind of vanishing of h
igher cohomologies result. This is a\njoint work with Christopher Manon. W
e note that\, independently and\naround the same time but from a different
point of view\, Khan and\nMaclagan also have arrived at (basically) the s
ame notion (of a\ntropical toric vector bundle).

DESCRIPTION:Topic: When and How are (promise) Constraint Satisfaction Probl
ems Efficiently Solvable?\n\nSpeakers: Venkatesan Guruswami\, University o
f California\, Berkeley\n\nComputational problems exhibit a diverse range
of behaviors in terms\nof how quickly and effectively they can be solved.
What underlying\nmathematical structure (or lack thereof) in a computatio
nal problem\nleads to an efficient algorithm for solving it (or dictates i
ts\nintractability)? Given the vast landscape of problems and algorithmic
\napproaches\, it would be simplistic to hope for a universal theory\nexpl
aining the underpinnings of easiness/hardness. Yet\, in the realm\nof con
straint satisfaction problems (CSP)\, the algebraic dichotomy\ntheorem giv
es a definitive answer: a polynomial time algorithm exists\nwhen there are
non-trivial local operations called polymorphisms under\nwhich the soluti
on space is closed\; otherwise the problem is\nNP-complete. \n\nEmboldened
by this\, one might speculate a polymorphic principle in\nmore general co
ntexts\, with appropriate notions of symmetries\ngoverning the existence o
f efficientalgorithms. Beginning with some\nbackground on CSP and the poly
morphic approach to understand their\ncomplexity\, the talk will discuss s
ome extensions beyond CSP where the\npolymorphic principle seems promising
(yet far from understood). In\nparticular\, we will discuss ``promise CSP
'' where one is allowed to\nsatisfy a relaxed version of the constraints\,
a framework that\nincludes problems such as approximate graph coloring an
d discrepancy\nminimization. We will provide glimpses of the emerging theo
ry\ncharacterizing the (in)tractability of interesting classes of promise
\nCSP and the ability of natural classes of algorithms (linear and\naffine
relaxations) to solve them\, and highlight some of the many\nchallenges t
hat remain.

DESCRIPTION:Topic: Towards Generalized Schubert Varieties and Anabelian Mat
roids\n\nSpeakers: Mateusz Michalek\, Institute for Advanced Study\n\nAbst
ract: The groundbreaking results by Huh (further extended in joint\nwork w
ith Adiprasito and Katz) allowed to associate to a matroid a\nclass in the
Chow ring of the permutohedral variety. The technique\nturned out to be e
specially powerful\, as certain invariants of the\nmatroid could be expres
sed as intersection products in this Chow ring.\nCan this technique be use
d further\, beyond matroids and the\npermutohedral variety?\n\nWe will poi
nt out very explicit analogies of the work of Huh and\nSchubert. This will
bring us to applications e.g. in statistics\,\nthrough maximum likelihood
degree. \n\nFinally\, we will go back to combinatorics\, presenting close
d formulas\nfor mixed Eulerian numbers.

DESCRIPTION:Topic: The External Activity Complex of a Pair of Matroids\n\nS
peakers: Andrew Berget\, Institute for Advanced Study\n\nAbstract: I will
introduce the external activity complex of an ordered\npair of matroids on
the same ground set. This is the combinatorial\nanalogue of the Schubert
variety of an ordered pair of linear\nsubspaces of a fixed space\, which i
s also new. These constructions\ngeneralize and extend the well-studied no
tion of external activity for\na matroid basis\, and the Schubert variety
of a single linear space\,\nwhich occur in the bivariate setting when one
of the matroids is\nuniform of rank 1. Certain Betti numbers of the extern
al activity\ncomplex of a pair determine the Euler characteristic of vario
us\n(non-positive) tautological classes of matroids\, and this can be used
\nto give a positive formula for Speyer's matroid invariant\n$\(\omega(M)\
)$. This is on-going work with Alex Fink.

DESCRIPTION:Topic: On Type II String Theory on $AdS_3$ x $S^3$ x $T^4$ and
Symmetric Orbifolds\n\nSpeakers: Erez Urbach\, Institute for Advanced Stud
y\n\nABSTRACT: I will present some questions and answers regarding the\ndu
ality between 1+1-dimensional superconformal field theory and type\nII str
ing theory on $AdS_3 \times S^3 x T^4$.\n\nFor one unit of NS-NS 5-brane f
lux ($Q_5$=1)\, this string theory has\nbeen suggested to be dual to a gra
nd-canonical ensemble of\n$T^{4N}/S_N$ free symmetric orbifold CFTs. We ex
plain how the string\ngenus expansion emerges to all orders for the free o
rbifold\ngrand-canonical correlation functions. \n\nWe also discuss how th
e strong coupling limit of the NS-NS string\ntheory arises (even at large
$N$) in the free orbifold description\,\nand argue why this limit does not
have a weakly coupled R-R\ndescription.\n \nThe dual CFT includes (for al
l values of $Q_5$) an extra $T^4$ factor\nwhich decouples from perturbativ
e string theory. We discuss the\nexactly-marginal deformations that relate
the different values of\n$Q_5$\, including the precise $J{\bar J}$ deform
ations mixing this\nextra $T^4$ with the symmetric orbifold.\n\n

DESCRIPTION:Topic: Paths to Matroid Representations\n\nSpeakers: Tong Jin\,
Georgia Institute of Technology\n\nAbstract: In this talk\, I will first
review previous works on matroid\nrepresentations initiated by Tutte in 19
58\, generalized by Dress and\nWenzel in the 1980s\, and refined by Baker\
, Bowler\, and Lorscheid more\nrecently using the language of F1-algebra.
It turns out that one of\nthe key ingredients of a 'universal' proof of ma
ny representation\ntheorems is a connectivity (or homotopy) statement of t
he lattice of\nflats of a matroid that confirms the existence of a certain
path of\nhyperplanes. Next\, I will extend this theory to orthogonal matr
oids.\nOrthogonal matroids appear in many natural ways to generalize a\nma
troid\, such as type D_n Coxeter matroids or tight 2-matroids. I will\nals
o describe the 'lattice' of an orthogonal matroid and give a\nconnectivity
statement for the orthogonal matroid that produces as\nwell many nice the
orems of their representations.

DESCRIPTION:Topic: Baker-Bowler Theory for Lagrangian Grassmannians\n\nSpea
kers: Donggyu Kim\, Korea Advanced Institute of Science and Technology \n
\nAbstract: Baker and Bowler (2019) showed that the Grassmannian can be\nd
efined over a tract\, a field-like structure generalizing both partial\nfi
elds and hyperfields.\n\nThis notion unifies theories for matroids over pa
rtial fields\,\nvaluated matroids\, and oriented matroids.\n\nWe extend Ba
ker-Bowler theory to the Lagrangian Grassmannian which is\nthe set of maxi
mal isotropic subspaces in a $2n$-dimensional\nsymplectic vector space.\n
\nBy Boege et al. (2019)\, the Lagrangian Grassmannian is parameterized\ni
nto the projective space of dimension $2^{n-2}(4+\binom{n}{2})-1$ and\nits
image is cut out by certain quadrics.\n\nWe simplify a list of quadrics s
o that these are apparently induced by\nthe Laplace expansions only concer
ning principal and almost-principal\nminors of a symmetric matrix.\n\nFrom
the idea that the strong basis exchange axiom of matroids\ncaptures the c
ombinatorial essence of the Grassmann-Pl\'{u}cker\nrelations\, we define m
atroid-like objects\, called antisymmetric\nmatroids\, from the quadrics f
or the Lagrangian Grassmannian.\n\nWe also provide its cryptomorphic defin
ition in terms of circuits\ncapturing the orthogonality and maximality of
vectors in a Lagrangian\nsubspace.\n\nWe define antisymmetric matroids ove
r tracts in two equivalent ways\,\nwhich generalize both Baker-Bowler theo
ry and the parameterization of\nthe Lagrangian Grassmannian.\n\nIt provide
s a new perspective on the Lagrangian Grassmannian over\nhyperfields such
as the tropical hyperfield and the sign hyperfield.\n\nOur proof involves
a homotopy theorem for graphs associated with\nantisymmetric matroids\, ge
neralizing Maurer's homotopy theorem for\nmatroids.\n\nWe also prove that
if a point in the projective space satisfies the\n$3$-/$4$-term quadratic
relations for the Lagrangian Grassmannian and\nits supports form the bases
of an antisymmetric matroid\, then it\nsatisfies all quadratic relations\
, which is motivated by the earlier\nwork of Tutte (1958) for matroids and
the Grassmannian.

DESCRIPTION:Topic: Complexity of Log-concave Inequalities in Matroids\n\nSp
eakers: Swee Hong Chan\, Rutgers University\n\nA sequence of nonnegative r
eal numbers $a_1\, a_2\, \ldots\, a_n$\, is\nlog-concave if $a_i^2 \geq a_
{i-1}a_{i+1}$ for all $i$ ranging from 2\nto $n-1$. Examples of log-concav
e inequalities range from inequalities\nthat are readily provable\, such a
s the binomial coefficients $a_i =\n\binom{n}{i}$\, to intricate inequalit
ies that have taken decades to\nresolve\, such as the number of independen
t sets $a_i$ in a matroid $M$\nwith $i$ elements (otherwise known as the f
irst Mason's conjecture\;\nand was resolved by June Huh in 2010s in a rema
rkable breakthrough).\nIt is then natural to ask if it can be shown that t
he latter type of\ninequalities is intrinsically more challenging than the
former. In\nthis talk\, we provide a rigorous framework to answer this ty
pe of\nquestions\, by employing a combination of combinatorics\, complexit
y\ntheory\, and geometry.\n\nThis is a joint work with Igor Pak.

DESCRIPTION:Topic: MM-curves\n\nSpeakers: Mario Kummer\, Technische Univers
ität Dresden\n\nFor an embedded stable curve over the real numbers we intr
oduce a\nhyperplane arrangement in the tangent space of the Hilbert scheme
. The\nconnected components of its complement are labeled by embeddings of
\nthe graph of the stable curve to a compact surface. We explain how the\n
real type of a deformation of the curve is determined by the topology\nof
such a surface. Finally\, we prove that a so-called graph curve is\nthe sp
ecial fiber of a maximal Mumford curve (MM-curve) if and only if\nthe grap
h is planar.\n\nThis is based on a joint work with Bernd Sturmfels and Ral
uca Vlad.

DESCRIPTION:Topic: The Moduli Space of Matroids\n\nSpeakers: Oliver Lorsche
id\, Institute for Advanced Study\n\nLecture Series Framework:_ A unifyin
g framework for F1-geometry\,\ntropical schemes and matroid theory. In thi
s series of 3 lectures\, I\nwill present a recent approach towards F1-geom
etry and its links to\ntropical geometry\, matroid theory\, Lorentzian pol
ynomials\, buildings\nand cluster algebras. Most of this is joint work wi
th Matthew Baker\,\namong several other collaborators including June Huh a
nd Mario\nKummer._\n\nThis first lecture is geared to a general audience.
Its purpose is to\ngive an impression of what the moduli space of matroids
is and use\nderived invariants to prove results about realizations of mat
roids\nover fields.\n\nIn more detail\, I will give a primer to Baker-Bowl
er's theory of\nmatroids with coefficients and explain how to define a sch
eme theory\nfrom exotic algebraic objects (so-called bands\, which general
ize\nrings\, similar to how pastures generalize fields). This allows us to
\nconstruct Grassmannians over F1\, which turn out to be moduli spaces of
\nmatroids. \n\nThe residue fields of these moduli spaces control the repr
esentation\ntheory of the corresponding matroids. A structural study of th
ese\ninvariants leads to results in the representation theory of matroids.
\nWe will showcase this in a simple example.

DESCRIPTION:Topic: Foundations of Matroids\n\nSpeakers: Oliver Lorscheid\,
Institute for Advanced Study\n\nThe second lecture features the nuts and b
olts of the invariants from\nfirst lecture\, which we call foundations. We
explain the structure\ntheorem for foundations of ternary matroids\, whic
h is rooted in\nTutte's homotopy theorem. We show how this theorem implies
a series of\nresults about the representation theory of ternary matroids.
\n\nAs another application of foundations\, we demonstrate a short proof o
f\na folklore theorem (attributed to Laurent Lafforgue) about the\nrealiza
tion space of a rigid matroid. Yet another application passes\nthrough the
relation between Lorentzian polynomials with matroids over\ntriangular hy
perfields\, which lets us answer (negatively)\nconjectures/questions of Pe
tter Branden about the topological type of\nthe spaces of Lorentzian and s
table polynomials.

DESCRIPTION:Topic: Tits's Dream: Buildings Over F1 and Combinatorial Flag V
arieties\n\nSpeakers: Oliver Lorscheid\, Institute for Advanced Study\n\nT
he theme of the third lecture is the notion of points over F1\, the\nfield
with one element. Several heuristic computations led to certain\nexpectat
ions on the set of F1-points: for example the Euler\ncharacteristic of a s
mooth projective complex variety X should be\nequal to the number of F1-ra
tional points of a suitable F1-model.\nWhile a literal interpretation of F
1-points as morphisms from Spec F1\ninto X gives the wrong answers\, we fi
nd a natural interpretation in\nterms of points over the Krasner hyperfiel
d. This leads to a natural\nrealization of Tits's proposed geometries over
F1 as the 'tip of the\niceberg' inside Borovic-Gelfand-White's combinator
ial flag varieties.\n\nAs far as time allows\, we explain how this phenome
non extends to an\ninterpretation of structure constants of cluster algebr
as in terms of\nquiver matroids. Namely\, the Caldero-Chapoton formula yie
lds an\nexplicit description of the cluster algebra of a tame quiver in te
rms\nof elementary expressions in the Euler characteristics of associated
\nquiver Grassmannians. The aforementioned principle (which is proven\nfor
these instances) identifies the Euler characteristics with the\nnumber of
certain quiver matroids\, which are diagrams of matroids and\nstrong maps

DESCRIPTION:Topic: Lower Bound Barriers in Complexity Theory and Overcoming
Them With Geometry\n\nSpeakers: Joseph Landsberg\, Texas A&M University\n
\nChapter 14 of the classic text 'Computational Complexity' by Arora and\n
Barak is titled 'Circuit lower bounds: complexity theory's Waterloo'.\nI w
ill discuss the lower bound problem in the context of algebraic\ncomplexit
y where there are barriers discovered by\nEfremenko-Garg-Oliveira-Wigderso
n. I'll begin with a history of lower\nbounds in the setting of tensors an
d conclude with a discussion of\nrecent developments. Mathematically this
is a story of going\nfrom linear algebra\, to algebraic geometry and repre
sentation theory\,\nto deformation theory and commutative algebra. No prio
r knowledge of\nthe mathematics or complexity theory will be needed.

DESCRIPTION:Topic: Tensors of Minimal Border Rank\n\nSpeakers: Joseph Lands
berg\, Texas A&M University\n\nA class of tensors\, called 'concise (m\,m\
,m)-tensors of minimal\nborder rank'\, play an important role in proving
upper bounds for the\ncomplexity of matrix multiplication. For that reason
Problem 15.2 of\n'Algebraic Complexity Theory' by Bürgisser\, Clausen and
Shokrollahi\nis to classify tensors of minimal border rank. It is now now
\nunderstood that this question is equivalent to notoriously difficult\nqu
estions in algebraic geometry and commutative algebra. However the\nfull q
uestion is not what is needed for complexity theory. I will\nexplain recen
t progress on the question in several directions. A\nsurprising role is pl
ayed by degree seven zero dimensional local\nGorenstein schemes.
