DESCRIPTION:Topic: Rounding Large Independent Sets on Expanders\n\nSpeakers
: Tim Hsieh\n\nIn this talk\, we will present a new approach for approxima
ting large\nindependent sets when the input graph is a one-sided expander—
that\nis\, the uniform random walk matrix of the graph has second eigenval
ue\nbounded away from 1. Specifically\, we show a polynomial time algorith
m\nthat can find linear-sized independent sets in one-sided expanders\ntha
t are almost $3$-colorable or promised to contain a $0.499n$-sized\nindepe
ndent set.\n\nAll prior algorithms that beat the worst-case guarantees for
the\nproblem rely on bottom eigenspace enumeration techniques\, which bui
ld\non a classical work of Alon and Kahale and require two-sided expansion
\n(i.e.\, bounded number of negative eigenvalues of magnitude close to\n1)
. Such techniques provably fail in our setting because in contrast\nto bot
tom eigenspace enumeration that naturally extends to\n$k$-colorable graphs
for any fixed constant $k$\, we observe that\nfinding linear-sized indepe
ndent sets in almost $4$-colorable\nexpanding graphs (as opposed to almost
$3$-colorable graphs in our\nalgorithmic result above) is NP-hard assumin
g the Unique Games\nConjecture.\n\nOur algorithms rely on a new framework
for rounding sum-of-squares\nrelaxations of the independent set problem ba
sed on a combinatorial\napproximate packing property—in any graph that sat
isfies one-sided\nspectral expansion (in fact\, a weaker vertex expansion
property\nsuffices)\, the total number of large independent sets with smal
l\npairwise intersections is small.\n\nBased on joint work with Mitali Baf
na and Pravesh K. Kothari.

DESCRIPTION:Topic: Symplectic Aspects of the Hilbert-Smith Conjecture and $
p$-adic Actions.\n\nSpeakers: Egor Shelukhin\n\nI will discuss a recent pr
oof of new cases of the Hilbert-Smith\nconjecture for actions by homeomorp
hisms of symplectic nature. In\nparticular\, it rules out faithful actions
of the additive $p$-adic\ngroup in this setting and provides further obst
ructions to group\nactions in symplectic topology. The proof relies on a n
ew approach to\nthis circle of questions combined with power operations in
Floer\ncohomology and quantitative symplectic topology.

DESCRIPTION:Topic: Derived Hecke Action For Weight One Modular Forms Via Cl
assicality\n\nSpeakers: Gyujin Oh\n\nIt is known that a p-adic family of m
odular forms does not necessarily\nspecialize into a classical modular for
m at weight one\, unlike the\nmodular forms of weight 2 or higher. We will
explain how this\nobstruction to classicality leads to a 'derived' action
on modular\nforms of weight one\, which can be understood as the so-calle
d derived\nHecke operator at p. We will also investigate the role of the d
erived\naction in the study of p-adic periods of the adjoint of the weight
one\nmodular forms.

DESCRIPTION:Topic: Invariant Sets and Hyperbolic Periodic Orbits\n\nSpeaker
s: Viktor Ginzburg\n\nThe presence of hyperbolic periodic orbits or invari
ant sets often has\nan affect on the global behavior of a dynamical system
. In this talk\nwe discuss two theorems along the lines of this phenomenon
\, extending\nsome properties of Hamiltonian diffeomorphisms to dynamicall
y convex\nReeb flows on the sphere in all dimensions. The first one\,\ncom
plementing other multiplicity results for Reeb flows\, is that the\nexiste
nce of a hyperbolic periodic orbit forces the flow to have\ninfinitely man
y periodic orbits. This result can be thought of as a\nstep towards Franks
’ theorem for Reeb flows. The second result is a\ncontact analogue of the
higher-dimensional Le Calvez-Yoccoz theorem\nproved by the speaker and Gur
el and asserting that no periodic orbit\nof a Hamiltonian pseudo-rotation
is locally maximal. The talk is based\non a joint work with Erman Cineli\,
Basak Gurel and Marco Mazzucchelli.

DESCRIPTION:Topic: Quantum Mechanics\, Semidefinite Programming\, and Graph
Invariants\n\nSpeakers: Matthew Hastings\n\nThe central problem of physic
s and quantum chemistry is to find the\nground state energy of some physic
al system governed by quantum\nmechanics. In mathematical terms\, this me
ans finding the lowest\neigenvalue of some linear operator on a vector spa
ce with a tensor\nproduct structure. Since the dimension of the vector sp
ace grows\nexponentially with the size of the physical system\, the proble
m\nquickly becomes computationally intractable. Semidefinite\nprogramming
methods are one interesting way of approximating the\nsolution. Even the
se methods can become computationally difficult as\nthe order of the semid
efinite program increases\, but low order methods\ncan provide useful info
rmation. I will review some of these methods\,\nand give some positive an
d negative results showing their power and\nlimitations on various physica
l systems. Finally\, I will explain an\ninteresting new graph invariant s
uggested by these methods and give\nsome preliminary results on that invar
iant.

DESCRIPTION:Topic: Resolution of the Kohayakawa--Kreuter Conjecture \n\nSpe
akers: Raphael Steiner\n\nA graph $G$ is said to be Ramsey for a tuple of
graphs ($H_1\,...\,H_r$)\nif every $r$-coloring of the edges of $G$ contai
ns a monochromatic\ncopy of $H_i$ in color $i$\, for some $i$. A fundament
al question at\nthe intersection of Ramsey theory and the theory of random
graphs is\nto determine the threshold at which the binomial random graph
\n$G_{n\,p}$ becomes a.a.s. Ramsey for a fixed tuple ($H_1\,...\,H_r$)\, a
nd\na famous conjecture of Kohayakawa and Kreuter predicts this threshold.
\nEarlier work of Mousset-Nenadov-Samotij\, Bowtell-Hancock-Hyde\, and\nKu
perwasser-Samotij-Wigderson has reduced this probabilistic problem\nto a d
eterministic graph decomposition conjecture.\n\nIn this talk\, I will disc
uss history and background of this problem\nand sketch our recent proof (j
oint with M. Christoph\, A. Martinsson\,\nY. Wigderson) that the determini
stic graph decomposition conjecture is\ntrue\, thus resolving the Kohayaka
wa-Kreuter conjecture.

groups decomposes into\nsubcategories\, called Bernstein blocks. I will t
hen provide an\noverview of what we know about the structure of these Bern
stein\nblocks. In particular\, I will sketch how to use a joint project in
\nprogress with Adler\, Mishra and Ohara to reduce a lot of problems\nabou
t the representations of p-adic groups to problems about\nrepresentations
of finite groups of Lie type (compare the Terng\nlectures)\, where answers
are often already known or are at least\neasier to achieve.\n\n

DESCRIPTION:Topic: Integral Hecke Correspondences\n\nSpeakers: Si Ying Lee
\n\nShimura varieties are an important geometric object in the Langlands\n
program\, because the Hecke (adelic group) action allows us to view\nvario
us cohomology groups as Hecke modules. Moreover\, the cohomology\nadmits a
n integral structure when the Shimura variety has an integral\nmodel\, and
we hence want to extend this Hecke action integrally. I\nwill talk about
constructing integral models for Hecke correspondences\nin both the global
and local (Rapoport-Zink spaces) setting\, to get\nquasi-smooth derived (
formal) schemes. This is joint work in progress\nwith Keerthi Madapusi.

DESCRIPTION:Topic: Modular Generating Series for Real Quadratic Heegner Obj
ects\n\nSpeakers: Alice Pozzi\n\nAbstract: The theory of elliptic curves w
ith complex multiplication\nhas yielded some striking arithmetic applicati
ons\, ranging from (cases\nof) Hilbert’s Twelfth Problem to the Birch and
Swinnerton-Dyer\nConjecture. These applications rely on the construction o
f certain\n“Heegner objects”\, arising from imaginary quadratic points on
the\ncomplex upper half plane\; the most famous examples of these are\nHee
gner points. \n\nIn recent years\, conjectural analogues of these Heegner
objects for\nreal quadratic fields have been constructed via p-adic method
s. In\nthis talk\, I will discuss how Heegner objects for real quadratic\n
fields can be used to obtain modular generating series\, that is\,\nformal
q-series that are q-expansions of classical modular forms. This\nis joint
work with Judith Ludwig\, Isabella Negrini\, Sandra Rozensztajn\nand Hann
eke Wiersema.

akers: Charlotte Chan\n\nAbstract: Geometry and representation theory are
intertwined in deep\nand foundational ways. One of the most important inst
ances of this\nrelationship was uncovered in the 1970s by Deligne and Lusz
tig: the\nrepresentation theory of matrix groups over finite fields is enc
oded\nin the geometry of a natural 'partition' of flag varieties. Recent\n
developments have revealed rich connections between Deligne-Lusztig\nvarie
ties and geometry studied in number-theoretic contexts. In this\nlecture s

DESCRIPTION:Topic: Continuous Symmetry Breaking: A Rigorous Approach\n\nSpe
akers: Sara Daneri\n\nAt the base of spontaneous pattern formation is univ
ersally believed\nto be the competition between short range attractive and
long range\nrepulsive forces. Though such a phenomenon is observed in exp
eriments\nand simulations\, a rigorous understanding of the mechanisms at
its\nbase is still in most physical problems a challenging open problem.\n
The main difficulties are due to the nonlocality of the interactions\nand\
, in more than one space dimensions\, the symmetry breaking\nphenomenon (n
amely the fact that the interactions have a larger group\nof symmetries th
an that of their minimizers). \n\nIn this talk we consider a general class
of isotropic functionals in\ndimension $d\geq 2$\, typical in physical mo
dels\, in which a surface\nterm favouring pure phases competes with a nonl
ocal term with power\nlaw kernel favouring alternation between different p
hases. Close to\nthe critical regime in which the two terms are of the sam
e order\, we\ngive a rigorous proof of the conjectured symmetry breaking a
nd pattern\nformation for global minimizers\, in the shape of domains with
flat\nboundary (e.g. stripes or lamellae). \n\nAmong others\, our approac
h relies on detecting a nonlocal\ncurvature-type quantity which is control
led by the energy functional\nand whose finiteness implies flatness for su
fficiently regular\nboundaries. \n\nThis is a joint work with E. Runa.

obal theory is still largely\nopen. In my talk\, I will discuss the global
well-posedness of the\nstochastic Abelian-Higgs model in two dimensions\,
which is a geometric\nsingular SPDE arising from gauge theory. The proof
is based on a new\ncovariant approach\, which consists of two parts: First
\, we introduce\ncovariant stochastic objects\, which are controlled using
covariant\nheat kernel estimates. Second\, we control nonlinear remainder
s using a\ncovariant monotonicity formula\, which is inspired by earlier w
ork of\nHamilton. \n\nJoint work with Bjoern Bringmann.

speak about new joint work with Rachel Greenfeld and Marina\nIliopoulou in
which we address some classical questions concerning the\nsize and struct

be an integer distance set if the distance between\nany pair of points in
the set is an integer. Our main result is that\nany integer distance set i
n the plane has all but a very small number\nof points lying on a single l
ine or circle. From this\, we deduce a\nnear-optimal lower bound on the di
ameter of any non-collinear integer\ndistance set of size n and a strong u
pper bound on the size of any\ninteger distance set in [-N\,N]^2 with no t
hree points on a line and no\nfour points on a circle.

Ziegler\n\nABSTRACT: The Mobius function is one of the most important arit
hmetic\nfunctions. There is a vague yet well known principle regarding its
\nrandomness properties called the “Mobius randomness law'. It\nbasically
states that the Mobius function should be orthogonal to any\n'structured'
sequence. P. Sarnak suggested a far reaching conjecture\nas a possible for
malization of this principle. He conjectured that\n'structured sequences'
should correspond to sequences arising from\ndeterministic dynamical syste
ms. I will describe progress in recent\nyears towards these conjectures\,
building on major advances in\ndynamics\, additive combinatorics\, and ana
lytic number theory.

\nAfter a brief review of the Mostow-Sullivan rigidity theorem\, we will\n
discuss a new rigidity theorem for a Kleinian group and its various\nimpli
cations including a cross-ratio rigidity. A Kleinian group\nwhich admits
a finite sided fundamental domain without cusp is called\nconvex cocompact
. For a convex cocompact Kleinian group\, we also\npresent a measure-theor
etic rigidity theorem in terms of the Hausdorff\nmeasure on the limit set.
\n\nWe relate our rigidity problem with the Zariski density of the\nassoci
ated self-joining subgroup of the product PSL(2\, C)\times\nPSL(2\,C)\, wh
ich is a rank two semisimple real algebraic group. It is\noften hard to de
cide whether a given discrete subgroup of a semisimple\nreal algebraic gro
up is Zariski dense or not. We will discuss how we\nuse the dynamics of di
agonal flows on higher rank homogeneous spaces\nof infinite volume to prov
e these rigidity results. \n\n(This talk is based on joint work with Dong

DESCRIPTION:Topic: Random Lattices with Symmetries\n\nSpeakers: Maryna Viaz
ovska\n\nAbstract: What is the densest lattice sphere packing in the\nd-di
mensional Euclidean space? In this talk we will investigate this\nquestion
as dimension d goes to infinity and we will focus on the\nlower bounds fo
r the best packing density\, or in other words on the\nexistence results.
I will give a historical overview of the existence\nof dense lattice packi
ngs by H. Minkowski\, E. Hlawka\, C. L. Siegel\, C.\nA. Rogers\, and more
recently by S. Vance and A. Venkatesh. For a\nlong time the best asymptot
ic lower bounds on packing density were\nknown for lattice packings. Rece
ntly\, a new asymptotic lower bound for\nsphere packings in high dimension
s was proven by M.Campos\, M. Jensen\,\nM. Michelin\, and J. Sahasrabudhe.
This new bound is proven by a\ncombinatorial method and a dense packing g
uaranteed by their theorem\nis not necessarily a lattice packing. In the f
inal part of the lecture\nI will present a recent work done in collaborati
on with V. Serban and\nN. Gargava\, and Ilaria Viglino on the moments of t
he number of lattice\npoints in a bounded set for random lattices construc
ted from a number\nfield.

DESCRIPTION:Topic: Higher Order Fourier Uniformity of Bounded Multiplicativ
e Functions in Short Intervals\n\nSpeakers: Terence Tao\n\nAbstract: The H
igher order Fourier uniformity conjecture asserts that\non most short inte
rvals\, the Mobius function is asymptotically uniform\nin the sense of Gow
ers\; in particular\, its normalized Fourier\ncoefficients decay to zero.
This conjecture is known to be\nequivalent (after a 'logarithmic' averagi
ng) to Sarnak's conjecture on\nthe disjointness of the Mobius function fro
m zero entropy sequences. \nIn this talk we survey the known progress on t
his problem\, and the\nmain remaining barrier to its resolution\, namely t
o break the\nlogarithmic scale barrier.

DESCRIPTION:Topic: Distributions of Class Groups of Global Fields\n\nSpeake
rs: Melanie Matchett Wood\n\nAbstract: Cohen\, Lenstra\, and Martinet have
given highly influential\nconjectures on the distribution of class groups
of number fields\, the\nfinite abelian groups that control the factorizat
ion in number fields.\nMalle\, using tabulation of class groups of number
fields\, found that\nthe Cohen-Lenstra-Martinet heuristics for the distrib
utions of class\ngroups of extensions of a number field seemed incorrect w
hen the base\nfield contains roots of unity. We describe a new conjecture
for the\ndistribution of class groups (at primes not dividing the order of
the\nGalois group) that corrects for this issue. We explain how large q
\nlimit function field theorems\, along with new results on the moment\npr
oblem for random groups\, lead to proofs of new reflection principles\nove
r number fields and our conjecture. This talk is on joint work\nwith Will
Sawin.

DESCRIPTION:Topic: Measure and Topological Rigidity Beyond Homogeneous Dyna
mics\n\nSpeakers: Simion Filip\n\nAbstract: To study the asymptotic behavi
or of orbits of a dynamical\nsystem\, one can look at orbit closures or in
variant measures. When the\nunderlying system has a homogeneous structure\
, usually coming from a\nLie group\, with appropriate assumptions a wide r
ange of rigidity\ntheorems show that ergodic invariant measures and orbit
closures have\nto be well-behaved and can often be classified.\n\nI will d
escribe joint work with Brown\, Eskin\, and Rodriguez-Hertz\,\nwhich estab
lishes rigidity results for quite general dynamical systems\nhaving some h
yperbolicity. I will also explain some of the necessary\nassumptions as we
ll as the homogeneous structures that emerge. Time\npermitting\, I will al
so explain closely related joint work with Fisher\nand Lowe on geodesic fl
ows in negative curvature.

bvariety of the moduli space of principally polarized abelian\nvarieties $
A_g$ for any value of g. For $g<16$ the dimension is $g-1$\,\nwhile for $g
\geq 16$\, it is determined by the larged dimensional\ncompact Shimura su

using special varieties\, and functional\ntranscendence theory.

\n\nSpeakers: Elon Lindenstrauss\n\nAbstract: Ratner's landmark equidstrib

mathematical areas.\nRecently there has been considerable progress in the
long sought for\ngoal of getting effective equidistribution results for th
ese flows.\n\nOne of the famous applications of unipotent flow has been th
e proof by\nMargulis of the longstanding Oppenheim conjecture (independent
ly of\nRatner's work) by using unipotent dynamics. We show how using the n
ew\neffective equidistribution result one can get a quantitative and\neffe
ctive results regarding values of indefinite nonintegral quadratic\nforms.
We also discuss a problem pioneered by Sarnak regarding pair\ncorrelation
of eigenvalues on flat tori.\n\nThe works I will present and joint with A
mir Mohammadi\, Zhiren Wang\nand Lei Yang.

\, on the inertial manifold\, to a finite system of ordinary\ndifferential
equations. We will give a new proof of the existence of\nan inertial mani

ten invariants\nmore than 20 years ago. In ongoing work with Alex Ritter\
