DESCRIPTION:Topic: Optimization\, Complexity and Math (or\, can we prove P!
=NP by gradient descent?).\n\nSpeakers: Avi Wigderson\n\nAffiliation: Herb
ert H. Maass Professor\, School of Mathematics\n\nThis talk will summarize
a project I was involved in during the past 8\nyears. It started with att
empts to understand the PIT (Polynomial\nIdentity Testing) problem - a cen
tral problem involving randomness and\nhardness. It has led us to pursue m
any other goals. I hope to explain\nour most complete understanding we hav
e so far\, as well as challenges\nand open problems. The main messages of
this project are summarized\nbelow\; I plan to describe\, through examples
\, many of the concepts they\nrefer to\, and the evolution of ideas leadin
g to them. No special\nbackground is assumed. \n\n * The most basic tools
of convex optimization in Euclidean space\nextend to a far more general se
tting of Riemannian manifolds that\narise from the symmetries of noncommut
ative groups. We develop\nfirst-order and second-order algorithms\, and an
alyze their performance\nin general. While proving convergence bounds requ
ires heavy algebraic\nand analytic tools\, convergence itself depends in a
n elegant way on\nnatural ``smoothness’’ parameters\, in analogy with the
Euclidean\n(commutative) case. \n * These algorithms give exponential (or
better) improvements in\nrun-time for solving algorithmic many problems ac
ross CS\, Math and\nPhysics. In particular\, these include problems in alg
ebra (e.g.\ntesting rational identities in non-commutative variables)\, in
analysis\n(testing the feasibility and tightness of Brascamp-Lieb inequal
ities)\,\nin quantum information theory (to the quantum marginals problem)
\, in\nalgebraic geometry (to computing Kronecker coefficients)\, in\ncomp
utational complexity (to derandomizing new special cases of the\nPIT probl
em) and in optimization (to testing membership in large\,\nimplicitly desc
ribed polytopes). \n * The focus on symmetries exposes old and reveals new
relations\nbetween the problems above. Essentially\, they are all members
hip\nproblems in null cones and moment polytopes of natural group actions
\non natural spaces. Invariant theory\, which studies such group actions\,
\nplays an essential role in this development. In particular\, a\nbeautifu
l non-commutative duality theory (expending linear programming\nduality in
the commutative case)\, and notions of geodesic convexity\n(extending the
Euclidean one) and moment maps (extending the Euclidean\ngradient) are ce
ntral to the algorithms and their analysis.\nInterestingly\, most algorith
ms in invariant theory are\nsymbolic/algebraic\, and these new numeric/ana
lytic algorithms proposed\nhere often significntly improve on them. \n\nBa
sed on joint works with Zeyuan Allen-Zhu\, Peter Bürgisser\, Cole\nFranks\
, Ankit Garg\, Leonid Gurvits\, Pavel Hrubes\, Yuanzhi Li\, Visu\nMakam\,

DESCRIPTION:Topic: Why Do Cusp Forms Exist?\n\nSpeakers: A. Raghuram\n\nI
will begin this talk by reviewing the Eichler-Shimura isomorphism\nbetween
the space of cusp forms of weight k and level N\, and a certain\ncohomolo
gy group. Shimura called this cohomology group as parabolic\ncohomology. I
n the context of automorphic forms on higher groups\, such\na cohomology g
roup takes the form of cuspidal cohomology. The\nexistence of cusp forms o
f prescribed weight then may be reformulated\ninto the nonvanishing of cus
pidal cohomology with prescribed\ncoefficients. I will review the relevant
definitions to be able to\nstate the nonvanishing problem for cuspidal co
homology for GL(n) over\na number field. After briefly surveying what's kn
own\, I will discuss\nsome recent results obtained in joint work with Dars
han Nasit making\nsome modest progress towards this problem.

DESCRIPTION:Topic: The Diffraction Limit and Extremal Functions\n\nSpeakers
: Ankur Moitra\n\nIt is widely believed that the physics of diffraction im
poses certain\nfundamental limits on the resolution of an optical system.
In this\nwork we study the diffraction limit as a statistical inverse prob
lem\nin increasingly more realistic mathematical models and prove rigorous
\nupper and lower bounds on the sample complexity of resolving\nclosely-sp
aced point sources. Our techniques center around extremal\nfunctions\, nam
ely the Beurling-Selberg majorant and its\nhigher-dimensional generalizati
ons\, which we use to show the emergence\nof a sharp phase transition that
governs when it is possible to\nrecover fine-grained structure from low-f
requency measurements. \n\nBased on joint work with Sitan Chen.

DESCRIPTION:Topic: Learning from Dynamics\n\nSpeakers: Ankur Moitra\n\nLine
ar dynamical systems are the canonical model for time series data.\nThey h
ave wide-ranging applications and there is a vast literature on\nlearning
their parameters from input-output sequences. Moreover they\nhave received
renewed interest because of their connections to\nrecurrent neural networ
ks.\n\nBut there are wide gaps in our understanding. Existing works have o
nly\nasymptotic guarantees or else make restrictive assumptions\, e.g. tha
t\npreclude having any long-range correlations. In this work\, we give a\n
new algorithm based on the method of moments that is computationally\neffi
cient and works under essentially minimal assumptions. Our work\npoints to
several missed connections\, whereby tools from theoretical\nmachine lear
ning including tensor methods\, can be used in\nnon-stationary settings.
\n\nBased on joint work with Ainesh Bakshi\, Allen Liu\, and Morris Yau.

udied by\nClebsch (1871) and Klein (1873). Building on Hirzebruch's work i
n\nwhich he related these surfaces to a Hilbert modular surface\, we\ndedu
ced our bounds from a general result for integral points on coarse\nHilber
t moduli schemes. After explaining this deduction\, we discuss\nthe strate
gy of proof of the general result which combines the method\nof Faltings (
Arakelov\, Parsin\, Szpiro) with modularity\,\nMasser-Wuestholz isogeny es

ng\n\nCombinatorial discrepancy asks the following question: Given a groun
d\nset U and a collection S of subsets of U\, how do we color each element
\nin U red or blue so that each subset in S has almost an equal number\nof
each color? A straightforward idea is to color everyone uniformly\nand in
dependently at random. Our goal is to improve upon this simple\nrandom col
oring. In this talk\, we will introduce some basics of\ncombinatorial disc
repancy\, present a simple algorithm\, and discuss\nsome applications.

DESCRIPTION:Topic: Irregular Loci in the Emerton-Gee Stack for GL2\n\nSpeak
ers: Kalyani Kansal\n\nLet K be a finite extension of Qp. The Emerton-Gee
stack for GL2 is a\nstack of etale (phi\, Gamma)-modules of rank two. Its
reduced part\, X\,\nis an algebraic stack of finite type over a finite fie
ld\, and can be\nviewed as a moduli stack of two dimensional mod p represe
ntations of\nthe absolute Galois group of K. By the work of Caraiani\, Eme
rton\, Gee\nand Savitt\, it is known that in most cases\, the locus of mod
p\nrepresentations admitting crystalline lifts with specified regular\nHo
dge-Tate weights is an irreducible component of X. Their work relied\non a
detailed study of a closely related stack of etale phi-modules\nwhich adm
its a map from a stack of Breuil-Kisin modules with descent\ndata. In our
work\, we assume K is unramfied and further study this map\nwith a view to
studying the loci of mod p representations admitting\ncrystalline lifts w
ith small\, irregular Hodge-Tate weights. We\nidentify these loci as image
s of certain irreducible components of the\nstack of Breuil-Kisin modules
and obtain several inclusions of the\nnon-regular loci into the irreducibl
e components of X. This is joint\nwork with Rebecca Bellovin\, Neelima Bor
ade\, Anton Hilado\, Heejong Lee\,\nBrandon Levin\, David Savitt and Hanne
ke Wiersema.

DESCRIPTION:Topic: Shrinkage Under Random Restrictions\n\nSpeakers: Robert
Andrews\n\nRandom restrictions are a powerful tool used to study the compl
exity\nof boolean functions. Various classes of boolean circuits are known
to\nsimplify under random restrictions. A prime example of this\,\ndiscov
ered by Subbotovskaya more than 60 years ago\, is the fact that\nboolean f
ormulas over the {and\, or\, not} basis shrink in size when the\ninputs ar
e randomly restricted. Shrinkage can be used to prove worst-\nand average-
case lower bounds\, construct explicit pseudorandom\ngenerators\, and desi
gn satisfiability algorithms. This talk will\nsurvey what is known about s
hrinkage and its applications to formula\nlower bounds and pseudorandomnes
s. We will also discuss an analogue of\nshrinkage in the setting of algebr
aic formulas.

DESCRIPTION:Topic: Prismatic F-gauges and Fontaine-Laffaille Modules\n\nSpe
akers: Vadim Vologodsky\n\nWith every bounded prism Bhatt and Scholze asso
ciated a cohomology\ntheory of formal _p_-adic schemes. The prismatic coho
mology comes\nequipped with the Nygaard filtration and the Frobenius endom
orphism.\nThe Bhatt-Scholze construction has been advanced further by Drin
feld\nand Bhatt-Lurie who constructed a cohomology theory with values in a
\nstable infinity-category of prismatic F-gauges. The new cohomology\ntheo
ry is universal\, meaning that\, for every bounded prism\, the\nassociated
prismatic cohomology theory factors through the category of\nprismatic F-
gauges.\n\nIn this talk\, I will explain how a full subcategory of the cat
egory of\nprismatic F-gauges formed by objects whose Hodge-Tate weights li
e in\nthe interval [0\,p-2] is equivalent to the derived category of\nFont
aine-Laffaille modules with a similar weight constraint. In the\ngeometric
context\, this means that the prismatic F-gauge associated\nwith a formal
ly smooth scheme over _p_-adic integers of dimension <\np-1 can be recover
ed from its Hodge filtered de Rham cohomology\nequipped with the Nygaard r

DESCRIPTION:Topic: Gardner's Touching Cubes Problem\n\nSpeakers: Liam Bradw
in Baker\n\nIn 1971\, Martin Gardner proposed a deceptively simple problem
about\n'kissing cubes' in his Mathematical Games column in the Scientific
\nAmerican\, and more than three decades later it is still unsolved. In\nt
his talk I will introduce the problem\, the progress made so far on\nit\,
as well as some progress I've made recently.

r” (see\n[1\,2] below). In this game\, each player picks a number and the
larger\nnumber wins. The payoff matrix in this game is *infinite triangula

DESCRIPTION:Topic: Extending Generalization Theory to Address Phenomena in
Contemporary Machine Learning\n\nSpeakers: Shay Moran\n\nRecent years have
seen remarkable progress in the field of Machine\nLearning (ML). \n\nHowe
ver recent breakthroughs exhibit phenomena that remain unexplained\nand at
times contradict conventional wisdom. A primary reason for\nthis discrep
ancy is that classical ML theory adopts a worst-case\nperspective which of
ten appears overly pessimistic for explaining\npractical ML scenarios. In
reality data is rarely worst-case and\nexperimental evidence suggests that
often much less data is needed\nthan predicted by traditional theory. \n
\nIn this tutorial we will overview the classical Vapnik-Chervonenkis\nThe
ory along with two variations that offer distribution- and\ndata-dependent
perspectives. These variations complement the\nclassical theory's worst-c
ase (distribution-free) perspective and are\nwell-suited for leveraging sp
ecific properties of a given learning\ntask. A unifying theme among these
models is their combinatorial\nnature\, marking a continuation of the rel
ationship between machine\nlearning and combinatorics—a connection dating
back to the discovery\nof the VC dimension over 50 years ago.

DESCRIPTION:Topic: A Proof of the RM Code Capacity Conjecture\n\nSpeakers:
Emmanuel Abbé\n\nIn 1948\, Shannon used a probabilistic argument to show t
he existence\nof codes achieving channel capacity. In 1954\, Muller and Re
ed\nintroduced a simple deterministic code construction\, conjectured\nsho
rtly after to achieve channel capacity. Major progress was made\ntowards e
stablishing this conjecture over the last decades\, with the\ninvolvement
of various areas of discrete mathematics. In particular\,\nthe special cas
e of the erasure channel was settled in 2015 by Kudekar\net al.\, relying
on Bourgain-Kalai's sharp threshold theorem for\nsymmetric monotone proper
ties. The case of error channels remained\nhowever unsettled\, due in part
icular to the property being\nnon-monotone\, and the absence of techniques
to obtain fast local error\ndecay. In this talk\, we provide a proof of t
he conjecture. The proof\ncircumvents the requirement of monotone properti
es to establish first\na 'weak' threshold property that relies solely on s
ymmetries. From\nthere on\, the proof proceeds with a new boosting framewo
rk for coding\,\nusing sunflower structures and weight enumerator bounds f
rom\nSberlo-Shpilka to control the global error down to capacity. Joint\nw
ork with Colin Sandon.

conjecture\,\nthis problem is now completely resolved using the polynomial
method.\nIn this talk I will describe recent progress on its higher dimen

n\nprove that there are no 'interesting’ constructions (with size\nsmaller
than trivial) even if one asks for sets that only have large\nintersectio
n with a flat in every direction. This theorem turns\nout to have surpri

DESCRIPTION:Topic: Solid Modules and Six Functors for Quasi-Coherent Sheave
s\n\nSpeakers: Lenny Taelman\n\nQuasi-coherent sheaves cannot support a si
x-functor formalism in the\nsame way that e.g. \ell-adic sheaves do. Claus
en and Scholze have\nshown that this can be fixed by extending the categor
y of\nquasi-coherent sheaves to `solid sheaves’. In this talk we will\nske
tch an alternative proof of this. We will define solid modules in a\npurel
y algebraic way (without reference to condensed mathematics)\, and\nproduc
e f_! and f^! similarly to how it is done in SGA. This talk will\nbe logic
ally independent of the rest of the seminar. Based on a group\nproject at
the 2023 Stacks Project Workshop\, with Emilie Arvidsson\,\nFinn Bartsch\,
Thomas Brazelton\, Sheela Devadas\, Karim Réga\, Gleb\nTerentiuk.

DESCRIPTION:Topic: Tate Classes and Endoscopy for GSp4\n\nSpeakers: Naomi S
weeting\n\nWeissauer proved using the theory of endoscopy that the Galois
\nrepresentations associated to classical modular forms of weight two\napp
ear in the middle cohomology of both a modular curve and a Siegel\nmodular
threefold. Correspondingly\, there are large families of Tate\nclasses on
the product of these two Shimura varieties\, and it is\nnatural to ask wh
ether one can construct algebraic cycles giving rise\nto these Tate classe
s. It turns out that a natural algebraic cycle\ngenerates some\, but not a
ll\, of the Tate classes: to be precise\, it\ngenerates exactly the Tate c
lasses which are associated to generic\nmembers of the endoscopic L-packet
s on GSp4. In the non-generic case\,\none can at least show that all the T
ate classes arise from Hodge\ncycles. I'll explain these results and their
proofs\, which rely on the\ntheta correspondence.

peakers: Annalisa Massaccesi\n\nThe question of producing a foliation of t
he n-dimensional Euclidean\nspace with k-dimensional submanifolds which ar
e tangent to a\nprescribed k-dimensional simple vectorfield is part of the
celebrated\nFrobenius theorem: a decomposition in smooth submanifolds tan
gent to a\ngiven vectorfield is feasible (and then the vectorfield itself
is said\nto be integrable) if and only if the vectorfield is involutive. I
n\nthis seminar\, I will summarize the results obtained in collaboration\n
with G. Alberti\, A. Merlo and E. Stepanov when the smooth submanifolds\na
re replaced by weaker objects\, such as (integral or normal) currents\nor
even contact sets with 'some' boundary regularity. I will also\nprovide Lu
sin-type counterexamples to the Frobenius property for\nrectifiable curren
ts. Finally\, I will try to highlight the connection\nbetween involutivity
/integrability à la Frobenius and\nCarnot-Carathéodory spaces and how to a

DESCRIPTION:Topic: A High Dimensional Goldreich-Levin Theorem\n\nSpeakers:
Silas Richelson\n\nIn this work we prove a high dimensional analogue of th
e beloved\nGoldreich-Levin theorem (STOC 1989)\, which is the first _loca
l\nlist-decoding_ algorithm. We consider the following algorithmic\nprobl
em: given oracle access to a function $f: Z_q^m \longrightarrow\nZ_q^n$ su
ch that $Pr_{x ~ Z_q^m} [ f(x)=Ax ] \geq \epsilon$ for some\nmatrix $A \in
Z_q^{n x m}$ and $\epsilon>0$\, recover $A$ (or a list of\nall such matri
ces). \n\nThe original Goldreich-Levin theorem (which handles the case $n
=1$\nabove) actually handles the agreements $\epsilon \gt 1/q$ for any $n$
.\nHence\, we focus on _tiny _agreements $\epsilon \leq 1/q$. As stated\,
\nthis problem cannot be efficiently solved\, since when the list of\nmatr
ices $A$ with good agreement with $f$ might be exponentially\nlarge. Thus
we define a new notion of list-decoding\; a short list of\nsuch matrices `
`capturing'' all others.\n\nOur main theorem gives an algorithm which effi
ciently recovers a\n(small) list\, of size $O( \epsilon^{-1} )$\, of linea
r maps $A$ which\nsatisfy: (1) each $A$ good agreement with $f$\, and (2)
every linear\nmap which has good agreement with $f$\, also has good agreem
ent with\nsome map $A$ in our list. The proof makes novel use of Fourier\n
analysis.

DESCRIPTION:Topic: Rigidity and Flexibility of Periodic Hamiltonian Flows\n
\nSpeakers: Gabriele Benedetti\n\nAn old problem in classical mechanics is
the existence of periodic\nflows within specific classes of Hamiltonian s
ystems such as geodesic\nand magnetic flows\, and central forces. In the l
ast years\, interest in\nthis problem has been revitalized since recent re
search has unveiled a\ndeep relationship between periodic Hamiltonian flow
s and systolic\nquestions in symplectic and contact geometry. While only t
rivial\nexamples of periodic flows among magnetic and central systems exis
t\,\nZoll and\, later\, Guillemin have shown that there are many exotic\ne
xamples among geodesic flows on the two-sphere. Following Guillemin's\napp
roach\, the goal of this talk is to show how the Nash-Moser implicit\nfunc
tion theorem can be used to construct magnetic flows on the\ntwo-torus whi
ch are periodic for a single value of the energy. This is\njoint work with
Luca Asselle and Massimiliano Berti.

DESCRIPTION:Topic: Stable Homology and the BKPLR Heuristics Over Function F
ields\n\nSpeakers: Jordan Ellenberg\n\nA basic question in arithmetic stat
istics is: what does the Selmer\ngroup of a random abelian variety look l
ike? This question is\ngoverned by the Poonen-Rains heuristics\, later ge
neralized by\nBhargava-Kane-Lenstra-Poonen-Rains\, which predict\, for ins
tance\, that\nthe mod p Selmer group of an elliptic curve has size p+1 on
average. \nResults towards these heuristics have been very partial but hav
e\nnonetheless enabled major progress in studying the distribution of\nran
ks of abelian varieties.\n\n \n\nWe will describe new work\, joint with Aa
ron Landesman\, which\nestablishes a version of these heuristics for the m
od n Selmer group\nof a random quadratic twist of a fixed abelian variety
over a global\nfunction field. This allows us\, for instance\, to bound t
he\nprobability that a random quadratic twist of an abelian variety A over
\na global function field has rank at least 2\, and to bound the\ndiscrepa
ncy between odd and even Selmer rank. The method is very\nmuch in the spi
rit of earlier work with Venkatesh and Westerland which\nproved a version
of the Cohen-Lenstra heuristics over function fields\nby means of homologi
cal stabilization for Hurwitz spaces. So part of\nthe goal of this talk i
s to give a general picture\nof _how_ questions in arithmetic statistics o
ver function fields can\nbe reduced to topological questions about homolog
ical stabilization\,\nand more speculatively\, _which_ questions can be so
reduced\, which I\nhope will also serve as a good lead-in to talks by Pet
ersen and\nWesterland later this week.

DESCRIPTION:Topic: The Stable Homology of the Braid Group With Coefficients
Arising From the Hyperelliptic Representation\n\nSpeakers: Craig Westerla
nd\n\nThe braid group B_{2g+1} has a description in terms of the\nhyperell
iptic mapping class group of a curve X of genus g. This\nequips it with a
n action on V = H_1(X)\, and we may produce a wealth of\nnew representatio
ns S^{\lambda}(V) by applying Schur functors to V.\n The goal of this talk
is to describe the stable (in g) group\nhomology of these representations
. \n\n \n\nFollowing an idea of Randal-Williams in the setting of the ful
l\nmapping class group\, one may extract these homology groups as Taylor\n
coefficients of the functor given by the stable homology of the space\nof
maps from the universal hyperelliptic curve to a varying target\nspace. W
e compute that stable homology by way of a scanning\nargument\, much as in
Segal’s original computation of the stable\nhomology of configuration spa
ces.\n\n \n\nThis is joint work with Bergström\, Diaconu\, and Petersen.
Dan will\nspeak afterwards on the application of these results to the conj
ecture\nof Andrade-Keating on moments of quadratic L-functions in the func
tion\nfield setting.

DESCRIPTION:Topic: Moments of Families of Quadratic L-Functions Over Functi
on Fields Via Homotopy Theory\n\nSpeakers: Dan Petersen\n\nThis is a repor
t of joint work with Bergström-Diaconu-Westerland and\nMiller-Patzt-Randal
-Williams.\n\nBased on random matrix theory\, Conrey-Farmer-Keating-Rubins
tein-Snaith\nhave conjectured precise asymptotics for moments of families
of\nquadratic L-functions over number fields. There is an extremely\nsimil
ar function field analogue\, worked out by Andrade-Keating. I will\nexplai
n that one can relate this problem to understanding the homology\nof the b
raid group with certain symplectic coefficients. With\nBergström-Diaconu-W
esterland we compute the stable homology groups of\nthe braid groups with
these coefficients\, together with their\nstructure as Galois representati
ons. (This will be explained in Craig\nWesterland's lecture on Nov 2.) We
moreover show that the answer\nmatches the number-theoretic predictions. W
ith\nMiller-Patzt-Randal-Williams we prove an improved range for\nhomologi
cal stability with these coefficients. (This will be explained\nin my lect
ure on Nov 3.) Together\, these results imply the conjectured\nasymptotics
for all moments in the function field case\, for all\nsufficiently large
(but fixed) q.

DESCRIPTION:Topic: Uniform Twisted Homological Stability\n\nSpeakers: Dan P
etersen\n\nHomological stability is now well established as an organizing
\nprinciple and computational tool in algebraic topology and other\nareas.
In many cases it is of interest to obtain homological stability\nwith twi
sted coefficients\, and the standard choice of such\ncoefficients are the
*polynomial coefficient systems*. All\nknown approaches to homological sta
bility with polynomial\ncoefficients produce a stable range depending on t
he degree of\npolynomiality. I will explain a method of obtaining uniform
stable\nranges for some classes of groups and coefficients of natural\nint
erest. This has important consequences in arithmetic statistics\,\ndiscuss

DESCRIPTION:Topic: Locally Maximal Closed Orbits of Reeb Flows\n\nSpeakers:
Marco Mazzucchelli\n\nA compact invariant set of a flow is called locally
maximal when it is\nthe largest invariant set in some neighborhood. In th
is talk\, based on\njoint work with Erman Cineli\, Viktor Ginzburg\, and B
asak Gurel\, I will\npresent a 'forced existence' result for the closed or
bits of certain\nReeb flows on spheres of arbitrary odd dimension:\n\n - I
f the contact form is non-degenerate and dynamically convex\, the\npresenc
e of a locally maximal closed orbit implies the existence of\ninfinitely m
any closed orbits. \n\n- If the locally maximal closed orbit is hyperbolic
\, the assertion of\nthe previous point also holds without the non-degener
acy and with a\nmilder dynamically convexity assumption. \n\nThese stateme
nts extend to the Reeb setting earlier results of Le\nCalvez-Yoccoz for su
rface diffeomorphisms\, and of Ginzburg-Gurel for\nHamiltonian diffeomorph
isms of certain closed symplectic manifolds. \n

DESCRIPTION:Topic: Lambda Rings\, Random Matrices\, and L-Functions\n\nSpea
kers: Sean Howe\n\nClassical probability theory is set up to handle random
variables\nwhose values are a single complex number. What happens if our
random\nvariable is instead a multi-set of complex numbers? For example\,
on\nthe group of n by n orthogonal matrices\, you might want to study the
\nrandom variable that sends a matrix to its eigenvalues. Or\, if you're\n
a number theorist\, you might want to consider the random variable on\nthe
finite set of smooth plane curves over a finite field $F_q$ that\nsends a
curve C to the zeroes of its L-function. In this conversation\,\nwe'll ex
plain how a theory of probability for random variables valued\nin an algeb
raic structure called a lambda ring can help study these\nquestions. As a
concrete example\, we will sketch how this perspective\ncan be used to giv
e a simple proof a theorem of Diaconis and\nShahshahani on traces of power
s in classical groups\, and how this\nrelates to the behavior of zeros of
L-functions.

DESCRIPTION:Topic: A Definition of Spectral Gap for Nonreversible Markov Ch
ains\n\nSpeakers: Sourav Chatterjee\n\nWhile the notion of spectral gap is
a fundamental and very useful\nfeature of reversible Markov chains\, ther
e is no standard analogue of\nthis notion for nonreversible chains. In thi
s talk\, I will present a\nsimple proposal for spectral gap of nonreversib
le chains\, and show\nthat it shares all of the nice properties of the rev
ersible spectral\ngap. The most important property of this spectral gap is
that its\nreciprocal gives an exact characterization\, with upper and low
er\nbounds\, of the time required for convergence of empirical averages.\n
This works even if there is no contraction\, such as in dynamical\nsystems
.

DESCRIPTION:Topic: Symplectic Capacities of Domains Close to a Ball and Geo
desics in the Space of Contact Forms\n\nSpeakers: Alberto Abbondandolo\n\n
An old open question in symplectic geometry asks whether all\nnormalised s
ymplectic capacities coincide for convex domains in the\nstandard symplect
ic vector space. I will show that this question has a\npositive answer for
smooth convex domains which are $C^2$-close to a\nEuclidean ball. This is
related to the question of existence of\nminimising geodesics in the spac
e of contact forms on a closed contact\nmanifold equipped with a Banach-Ma
zur-like metric. On the other hand\,\nthere are smooth domains which are a
rbitrary $C^1$-close to the ball\nfor which the ball capacity is strictly
smaller than the cylindrical\ncapacity. This talk is based on recent joint
work with Gabriele\nBenedetti and Oliver Edtmair.\n \n\n \n\n

DESCRIPTION:Topic: The Iterative Win-Win Method\, and Explicit Construction
s (without) Using It\n\nSpeakers: Hanlin Ren\n\nExplicit constructions of
'random-like' objects play an important role\nin complexity theory and pse
udorandomness. For many important objects\nsuch as prime numbers and rigid
matrices\, it remains elusive to find\nfast deterministic algorithms for
constructing them unconditionally\,\ndespite the fact that these objects a
re abundant and can be easily\nfound using randomness.\n\nThis lecture wil
l focus on two recent results: (1) an infinitely-often\npseudodeterministi
c construction for primes (and in fact any dense\nproperty in polynomial t
ime)\; (2) a pseudodeterministic algorithm for\nthe range avoidance proble
m with an NP oracle\, which implies novel\nnear-maximum circuit lower boun
ds. Previously\, only\nsubexponential-time algorithms are known for both e
xplicit\nconstruction problems. The main theme underlying both results is
a new\niterative win-win method that improves upon previous win-win argume
nts\nand leads to polynomial time bounds.\n\nThe first half of the lecture
will provide basic backgrounds of the\niterative win-win method\, offerin
g a high-level introduction. The\nsecond half will elaborate on the result
(2). If time permits\, we will\nalso explore the recent surprising improv
ement by Li\n(https://eccc.weizmann.ac.il/report/2023/156) that gets rid o
f the\niterative win-win method and proves an almost-everywhere\nexponenti
al-size circuit lower bound.\n\nBased on joint works with Lijie Chen\, Shu
ichi Hirahara\, Zhenjian Lu\,\nIgor Oliveira\, and Rahul Santhanam. The re
sults on circuit lower\nbounds and range avoidance are subsumed by the wor
k of Zeyong Li.

DESCRIPTION:Topic: Essential Dimension via Prismatic Cohomology\n\nSpeakers
: Mark Kisin\n\nLet $f:Y \rightarrow X$ be a finite covering map of comple
x algebraic\nvarieties. The essential dimension of f is the smallest integ
er e such\nthat\, birationally\, f arises as the pullback of a covering $Y
^{'}\n\rightarrow X^{'}$ of dimension e\, via a map $X \rightarrow X^{'}$.
\nThis invariant goes back to classical questions about reducing the\nnumb
er of parameters in a solution to a general nth degree polynomial\,\nand a
ppeared in work of Kronecker and Klein on solutions of the\nquintic. \n\nI
will report on joint work with Benson Farb and Jesse Wolfson\, where\nwe
use prismatic cohomology\, to obtain lower bounds on the essential\ndimens
ion of certain coverings. For example\, we show that for an\nabelian varie
ty A of dimension g the multiplication by p map $A\n\rightarrow A$ has ess
ential dimension g for almost all primes p.\nPrismatic cohomology is used
to obtain lower bounds on the coniveau\nfiltration on mod p cohomology\, a
nalogous to that obtained in\ncharacteristic 0 using Hodge theory.

DESCRIPTION:Topic: Prismatic F-gauges and Fontaine-Laffaille Modules\n\nSpe
akers: Vadim Vologodsky\n\nWith every bounded prism Bhatt and Scholze asso
ciated a cohomology\ntheory of formal p-adic schemes. The prismatic cohomo
logy comes\nequipped with the Nygaard filtration and the Frobenius endomor
phism.\nThe Bhatt-Scholze construction has been advanced further by Drinfe
ld\nand Bhatt-Lurie who constructed a cohomology theory with values in a\n
stable -category of prismatic F-gauges. The new cohomology theory is\nuni
versal\, meaning that\, for every bounded prism\, the associated\nprismati
c cohomology theory factors through the category of\nprismatic F-gauges.
\n\nIn this talk I will explain how a full subcategory of the category \no
f prismatic F-gauges formed by objects whose Hodge-Tate weights lie\nin th
e interval [0\,p-2] is equivalent to the derived category of\nFontaine-Laf
faille modules with a similar weight constrain. In the\ngeometric context\
, this means that the prismatic F-gauge associated\nwith a formally smooth
scheme over p-adic integers of dimension <\np-1 can be recovered from it
s Hodge filtered de Rham cohomology\nequipped with the Nygaard refined cry
stalline Frobenius endomorphism.\n\nThe talk is based on a joint work with

DESCRIPTION:Topic: Stacks in p-adic Hodge Theory of Rigid Spaces\n\nSpeaker
s: Arthur-Cesar Le Bras\n\nThe recent work of Drinfeld and Bhatt-Lurie led
to a new geometric\napproach to p-adic cohomology theories\, analogously
to what was done\nearlier in Hodge theory by Simpson. This stacky perspect
ive gives in\nparticular a new approach to p-adic non-abelian Hodge theory
\, by\nproviding a natural construction of a fully faithful p-adic Simpson
\nfunctor from Higgs(-Sen) bundles to v-bundles (in fact\, even a derived
\nversion) on some rigid spaces\, which we will discuss first.\n\nThe cons
truction of this functor is however limited to rigid spaces\nwith a smooth
formal model. Both to get rid of this restriction and to\nbetter understa
nd the geometric underpinnings of recent developments\nin Sen theory and t
he locally analytic Langlands program\, it is\nnatural to wonder whether D
rinfeld’s and Bhatt-Lurie’s stacks can\nalso be defined for arbitrary rigi
d spaces\, rather than formal\nschemes. The second part of the talk\, very
much in progress\, will\nexplain why such an extension seems indeed possi
ble.\n\nBased on joint work and discussions with Anschütz\, Heuer\, Rodrig
uez\,\nCamargo and Scholze.

DESCRIPTION:Topic: Quasicoherent Sheaves on the Relative Fargues-Fontaine C
urve\n\nSpeakers: Lucas Mann\n\nIn joint work in progress with Anschütz an
d Le Bras we aim to\nconstruct a 6-functor formalism for quasicoherent she
aves on the\nrelative Fargues-Fontaine curve over rigid-analytic varieties
(and\neven general v-stacks)\, providing new insights into the p-adic\nco
homology theories appearing in p-adic Hodge theory. In particular\,\nthe 6
-functor formalism should prove the conjectures by\nColmez-Gilles-Niziol o
n dualities of pro-étale Q_p-cohomology on\nStein spaces. While the detail

prove powerful v-descent results for\nquasicoherent sheaves on perfectoid
spaces\, which provide the\ntechnical foundation to construct the six func
tors.

DESCRIPTION:Topic: Strong Spatial Mixing for Colorings on Trees and its Alg
orithmic Applications\n\nSpeakers: Nitya Mani\n\nStrong spatial mixing (SS
M) is an important and widely studied\nquantitative notion of 'correlation
decay' for a variety of natural\ndistributions arising in statistical phy
sics\, probability theory\, and\ntheoretical computer science. One of the
most widely studied such\ndistributions is the uniform distribution over p
roper $q$-colorings on\na maximum degree $\Delta$ graph\, $\mu$. Provided
that $q \ge \Delta +\n1$\, any such graph has at least one proper $q$-colo
ring that can be\nidentified via e.g. a greedy search. It is a longstandin
g folklore\nconjecture that whenever $q$ satisfies this minimal inequality
\, $\mu$\nexhibits SSM and the correlations between the colors of vertices
in a\nsample from $\mu$ decay exponentially fast in the graph distance\nb
etween the vertices. However\, even the specialization of this basic\nques
tion to bounded-degree trees has remained wide open\, highlighting\nhow mu
ch there still is to learn about random colorings.\n\nApart from the nice
structural consequences of SSM\, notions of\ncorrelation decay (even restr
icted to trees) are of significant\ninterest in the theoretical computer s
cience community\; it is widely\nbelieved that as long as SSM holds on bou
nded-degree trees with $q$\ncolors\, one could obtain an efficient sampler
for $q$-colorings on all\nbounded-degree graphs via simple Markov chain a
lgorithms. \n\nWe essentially resolve the SSM conjecture on trees\, holds
for random\n$q$-colorings on trees of maximum degree $\Delta$ whenever $q
\ge\n\Delta + 3$. In the algorithmic direction\, we use SSM on trees to\ne
stablish optimal mixing of the Glauber dynamics (a classical Markov\nchain
) for sampling $q$-colorings on graphs of maximum degree $\Delta$\nand gir
th $g$_ _whenever $q \ge \Delta+3$.\n\nJoint work with Zongchen Chen\, Kui

rous proof that the\nHiggs mechanism can indeed generate mass in situation

(3)). I will present the first rigorous proof in this direction\,\nshowing
that SU(2) lattice Yang-Mills theory coupled to a Higgs field\ntransformi
ng in the fundamental representation of SU(2) has a mass gap\nat any value
of the coupling parameter\, provided that the interaction\nof the Higgs f

onsider a function on $R^n$ that can be written as a sum of functions\n$f

ing f by a reweighted sum using only a small\nnumber of summands has many
applications in CS theory\, mathematical\nanalysis\, data science\, and nu
merical linear algebra.\n\nWe'll see that sparsification is possible in su
bstantial generality.\nFor instance\, if the functions ${f_i}$ are arbitra
ry norms\, symmetric\nsubmodular functions\, or come from a general class
of linear models\,\nthen one can sparsify down to a number of terms that i
s nearly linear\nin the dimension. As an application\, we obtain algorithm
s with\nnear-optimal running time a variety of linear regression problems\
,\nincluding $l_p$ regression for $1 < p < 2$.\n\nThe most common way of b
uilding sparsifiers is by random sampling the\nfunctions $f_i$ to produce
a sparse reweighting. Attempting to analyze\nsuch a sampling algorithm nat
urally leads to the study of chaining\nmethods\, entropy numbers\, etc. In
the first part of the talk\, we will\nwalk through such a proof for the s

ng our methods to geodesic flows of surfaces\, we obtain\nthat the points
of lower-semicontinuity of the topological entropy\ninclude non-degenerate
metrics. In particular\, given a geodesic flow\nof such a metric with pos

r programs.\nIn both cases\, we are able to construct an explicit WPRG wit
h seed\nlength $\widetilde{O}\left(\log n \cdot \sqrt{\log(1/\varepsilon)}
+\n\log(1/\varepsilon)\right)$\, where $n$ is the length of the program\n
and $\varepsilon$ is the error of the WPRG. For comparison\, for both\nof
these models\, the best explicit unweighted PRGs known have seed\nlength $
\widetilde{O}(\log n \cdot \log(1/\varepsilon))$ (Meka\,\nReingold\, and T
al STOC 2019\; Braverman\, Rao\, Raz\, and Yehudayoff\nSICOMP 2014). Our W
PRG seed length is superior when $\varepsilon$ is\nsmall.\n\nOur results a

builds on the remarkable recent work by Ahmadinejad\,\nKelner\, Murtagh\,
Peebles\, Sidford\, and Vadhan (FOCS 2020) that gave a\nnear-logarithmic s

DESCRIPTION:Topic: What is an Incompressible Surface in a 3-manifold?\n\nSp
eakers: Anastasiia Tsvietkova\n\nFor a low-dimensional manifold\, one ofte
n tries to understand its\nintrinsic topology and geometry through its sub
manifolds\, in\nparticular of co-dimension 1. To be interesting and to giv
e some\ninformation\, such a submanifold should interact with the 3-manifo
ld in\na non-trivial way. In particular\, it was noticed before that prese
nce\nof embedded incompressible surfaces in a 3-manifold can give\ninforma
tion about that manifold. However to construct\, classify or\ncount such s
urfaces is a non-trivial task. We will start by explaining\nwhat is behind
the definitions\, and\, if the time allows\, will\neventually discuss a u
niversal upper bound for the number of\nnon-isotopic genus g surfaces embe
dded in a hyperbolic 3-manifold\,\npolynomial in hyperbolic volume of the
3-manifold. This touches on\nongoing joint work with Marc Lackenby\, anoth
er recent joint work with\nJessica Purcell\, and earlier joint work with J
oel Hass and Abigail\nThompson.

DESCRIPTION:Topic: Toward Better Depth Lower Bounds: A KRW-like theorem for
Strong Composition\n\nSpeakers: Or Meir\n\nOne of the major open problems
in complexity theory is proving\nsuper-logarithmic lower bounds on the de
pth of circuits. Karchmer\,\nRaz\, and Wigderson (Computational Complexity
5(3/4)\, 1995) suggested\napproaching this problem by proving that depth
complexity of a\ncomposition of two functions is roughly the sum of their
individual\ndepth complexities. They showed that the validity of this conj
ecture\nwould imply the desired lower bounds.\n\nThe intuition that underl
ies the KRW conjecture is that composition\nshould behave like a 'direct-s
um problem'\, in a certain sense\, and\ntherefore the depth complexity of
the composition should be the sum of\nthe individual depth complexities. N
evertheless\, there are two\nobstacles toward turning this intuition into
a proof: first\, we do not\nknow how to prove that the composition must be
have like a direct-sum\nproblem\; second\, we do not know how to prove tha
t the complexity of\nthe latter direct-sum problem is indeed the sum of th
e individual\ncomplexities.\n\nIn this talk\, we will describe a new work
that tackles the second\nobstacle. We will consider a notion of 'strong co
mposition' that is\nforced to behave like a direct-sum problem\, and see t
hat a variant of\nthe KRW conjecture holds for this notion. This result de
monstrates\nthat the first obstacle above is the crucial barrier toward re
solving\nthe KRW conjecture. Along the way\, we will discuss some general
\ntechniques that might be of independent interest.

DESCRIPTION:Topic: On Some Impact-like Hamiltonian Systems\n\nSpeakers: Ver
ed Rom-Kedar\n\nThe dynamics associated with mechanical Hamiltonian flows
with smooth\npotentials that include sharp fronts may be modeled\, at the
singular\nlimit\, by Hamiltonian impact systems: a class of generalized bi
lliards\nby which the dynamics in the domain’s interior are governed by\ns
mooth potentials and at the domain’s boundaries by elastic\nreflections. R
esults on persisting vs. non-persisting dynamics of such\nsystems will be
discussed. In some cases\, called quasi-integrable\, the\nlimit systems ha
ve fascinating behavior: their energy surfaces are\nfoliated by two dimens
ional level sets. The motion on each of these\nlevel sets is conjugated to
a directed motion on a translation\nsurface. The genus of the iso-energy
level sets varies - it is only\npiecewise constant along the foliation. Th
e metric data of the\ncorresponding translation surfaces and the direction
of motion along\nthem changes smoothly within each of the constant-genus
families.\nErgodic properties and quantum properties of classes of such sy
stems\nare established. Based on collaborations with: M. Pnueli\, K. Fracz

ipredictor — an online prediction algorithm that can be used to\nsimultane
ously obtain no regret guarantees to all Lipschitz convex\nloss functions.
\n * We show upper and lower bounds on the extent to which our regret\nrat
es can be improved. \n\nJoint work with Christopher Jung\, Omer Reingold a

DESCRIPTION:Topic: PDE and Discrete Models of 2D Quantum Materials\n\nSpeak
ers: Michael I. Weinstein\n\nWe consider 2D quantum materials (non-magneti
c and constant magnetic\nfield cases)\, modeled by a continuum Schroedinge
r operator\, whose\npotential is a sum of translates of an atomic well\, c
entered on the\nvertices of a discrete subset of the plane\, Omega. In the
regime of\ndeep potential wells (strong binding —> tight binding limit)\,
a\ncentered and rescaled resolvent operator converges to the resolvent of
\na discrete (tight-binding) effective Hamiltonian\, yielding a blown up\n
picture of the low-lying energy spectrum. Examples include the tight\nbind
ing limit of the single electron model for bulk graphene\n(Omega=honeycomb
lattice)\, a sharply terminated graphene half-space\,\ninterfaced with th
e vacuum along an arbitrary line-cut\, and the Harper\nmodel. For magnetic
Hamiltonians\, recent results on lower bounds for\nthe tunneling probabil
ity between identical wells\, in the presence of\na strong constant magnet
ic field\, play a central role. Finally\, we\npresent our current understa
nding of the spectrum of the tight binding\nHamiltonian which arises for t
he case of a graphene half-space\,\nterminated along an arbitrary rational
line-cut.
