DESCRIPTION:Topic: A uniform Bogomolov type of theorem for curves over glob
al fields\n\nSpeakers: Xinyi Yuan\n\nAffiliation: Beijing International Ce
nter for Mathematical Research\n\nIn the recent breakthrough on the unifor
m Mordell-Lang problem by\nDimitrov-Gao-Habegger and Kuhne\, their key res
ult is a uniform\nBogomolov type of theorem for curves over number fields.
In this talk\,\nwe introduce a refinement and generalization of the unifo
rm Bogomolov\nconjecture over global fields\, as a consequence of bigness
of some\nadelic line bundles in the setting of Arakelov geometry. The trea
tment\nis based on the new theory of adelic line bundles of Yuan--Zhang an
d\nthe admissible pairing over curves of Zhang.\n

DESCRIPTION:Topic: Expander Random Walks: A Fourier-Analytic Approach\n\nSp
eakers: Gil Cohen\n\nAffiliation: Tel Aviv University\n\nA random walk on
expanders\, despite its strong underlying\ncorrelations\, poses extremely
useful pseudorandom properties. The\nexpander hitting property and the exp
ander Chernoff are two such\nclassic examples. That is\, the AND function
and certain interval\nindicator functions are 'fooled' by expander random
walks. More\nrecently\, Ta-Shma proved that even the highly sensitive pari
ty\nfunction is fooled by expander random walks.\n\nWhat about other 'test
' functions? We prove that all symmetric\nfunctions are fooled by expander
random walks\, yielding a central\nlimit theorem for expander random walk
s with respect to the total\nvariation distance. Our approach is Fourier a
nalytic\, and as such\, it\nallows us to go beyond symmetric functions. We
show that sufficiently\ngood expanders fool bounded-depth circuits\, boun
ded-width read-once\nbranching programs\, and so forth.\n\nBased on joint
works with Peri and Ta-Shma\, and with Minzer\, Peleg\,\nPotechin and Ta-S
hma.\n

DESCRIPTION:Topic: Superpolynomial Lower Bounds Against Low-Depth Algebraic
Circuits I : An overview\n\nSpeakers: Srikanth Srinivasan\n\nAffiliation:
Aarhus University\n\nEvery multivariate polynomial P(x_1\,...\,x_n) can b
e written as a\nsum of monomials\, i.e. a sum of products of variables and
field\nconstants. In general\, the size of such an expression is the num
ber\nof monomials that have a non-zero coefficient in P.\n\nWhat happens i
f we add another layer of complexity\, and consider\nsums of products of s
ums (of variables and field constants)\nexpressions? Now\, it becomes unc
lear how to prove that a given\npolynomial P(x_1\,...\,x_n) does not have
small expressions. In this\nresult\, we solve exactly this problem.\n\nMor
e precisely\, we prove that certain explicit polynomials have\nno polynomi
al-sized 'Sigma-Pi-Sigma' (sums of products of\nsums) representations. We
can also show similar results\nfor Sigma-Pi-Sigma-Pi\, Sigma-Pi-Sigma-Pi-S
igma\, and so on for\nall 'constant-depth' expressions.\n\nIn part I of th
is two-part talk\, we will discuss the background\nbehind this result and
some basic results from this area. In part II\nof this talk\, we will give
details of the lower bound. \n\nBased on joint work of Nutan Limaye\, Sri
kanth Srinivasan\, and\nSébastien Tavenas.\n

DESCRIPTION:Topic: Superpolynomial Lower Bounds Against Low-Depth Algebraic
Circuits II : A more detailed approach\n\nSpeakers: Sébastien Tavenas\n\n
Affiliation: Université Savoie Mont Blanc Chambéry\n\nEvery multivariate p
olynomial P(x_1\,...\,x_n) can be written as a\nsum of monomials\, i.e. a
sum of products of variables and field\nconstants. In general\, the size
of such an expression is the number\nof monomials that have a non-zero coe
fficient in P.\n\nWhat happens if we add another layer of complexity\, and
consider\nsums of products of sums (of variables and field constants)\nex
pressions? Now\, it becomes unclear how to prove that a given\npolynomial
P(x_1\,...\,x_n) does not have small expressions. In this\nresult\, we so
lve exactly this problem.\n\nMore precisely\, we prove that certain explic
it polynomials have\nno polynomial-sized 'Sigma-Pi-Sigma' (sums of product
s of\nsums) representations. We can also show similar results\nfor Sigma-P
i-Sigma-Pi\, Sigma-Pi-Sigma-Pi-Sigma\, and so on for\nall 'constant-depth'
expressions.\n\nIn part I of this two-part talk\, we will discuss the bac
kground\nbehind this result and some basic results from this area. In part
II\nof this talk\, we will give details of the lower bound. \n\nBased on
joint work of Nutan Limaye\, Srikanth Srinivasan\, and\nSébastien Tavenas.

In the past decade convex integration has been established\nas a powerful
and versatile technique for the construction of weak\nsolutions of various
nonlinear systems of partial differential\nequations arising in fluid dyn
amics\, including the Euler and\nNavier-Stokes equations. The existence th
eorems obtained in this way\ncome at a high price: solutions are highly ir
regular\, non-\ndifferentiable\, and very much non-unique as there is usua
lly\ninfinitely many of them. Therefore this technique has often been\ntho
ught of as a way to obtain mathematical counterexamples in the\nspirit of
Weierstrass’ non-differentiable function\, rather than\nadvancing physical
theory\; “pathological”\, “wild”\,\n“paradoxical”\, “counterintuitive” ar
e some of the adjectives\nusually associated with solutions obtained via c
onvex integration. In\nthis lecture I would like to draw on some recent ex
amples to show that\nthere are many more sides to the story\, and that\, w
ith proper usage\nand interpretation\, the convex integration toolbox can
indeed provide\nuseful insights for problems in hydrodynamics.\n

DESCRIPTION:Topic: On singularity formation for energy super critical probl
ems\n\nSpeakers: Pierre Raphaël\n\nAffiliation: University of Cambridge\n
\nThe 4th Clay Millenium problem has a very simple formulation: may\nvisco
us incompressible fluids form a singularity in finite time? The\nanswer is
no in dimension two as proved by Leray in 1932\, but the\nthree dimension
al problem is out of reach. More generally\, the\ndescription of energy co
ncentration mechanisms for non linear waves\npossibly leading to the forma
tion of singularities is a canonical\nmathematical problem with deep physi
cal roots. These possibly highly\nunstable dynamics are difficult to detec
t numerically\, and there is\nstill little theoretical understanding of th
e underlying\nmechanisms. I will in this first lecture introduce model can
onical\nproblems and illustrate the concept of energy critical versus supe
r\ncritical models through the exposition of classical open problems in\nt
he field. \n

DESCRIPTION:Topic: Verifying The Unseen: Interactive Proofs for Label-Invar
iant Distribution Properties\n\nSpeakers: Guy Rothblum\n\nAffiliation: Wei
zmann Institute\n\nGiven i.i.d. samples drawn from an unknown distribution
over a large\ndomain [N]\, approximating several basic quantities\, such
as the\ndistribution's support size and its Shannon Entropy\, requires at
least\nroughly (N / \log N) samples [Valiant and Valiant\, STOC 2011].\n\n
Suppose\, however\, that we can interact with a powerful but untrusted\npr
over\, who knows the entire distribution. Can we use such a prover to\napp
roximately *verify* such statistical quantities more efficiently?\n\nWe sh
ow that this is indeed the case: a distribution's support size\,\nits entr
opy\, and its distance from the uniform distribution\, can all\nbe approxi
mately verified via a constant-round interactive proof\,\nwhere the verifi
er's running time\, the sample complexity\, and the\ncommunication complex
ity are all close to \sqrt{N}.\n\nMore generally\, we give a tolerant inte
ractive proof system with\nsimilar parameters for verifying a distribution
's proximity to any\nlabel-invariant property (any property that is invari
ant to\nre-labeling of the elements in the distribution's support).\n\nJoi

DESCRIPTION:Topic: Recent progress in query complexity I & II\n\nSpeakers:
Pei Wu\n\nAffiliation: Member\, School of Mathematics\n\nThe query model i
s one of the most basic computational models. In\ncontrast to the Turing
machine model\, fundamental questions regarding\nthe power of randomness a
nd quantum computing are\nrelatively well-understood. For example\, it is
well-known since the\n90s that deterministic\, randomized\, and quantum q
uery complexities are\npolynomially related for total functions\, and can
be arbitrarily\nseparated for partial functions. The follow-up question o
f what are\nthe largest separations between these models\, however\, is mo
re subtle\nand has resisted 20 years of attacks. In recent years\, a lot
of\nexciting progress is made. Just to mention a few (for total\nfunction
s):\n\n1. A quadratic separation between the deterministic query and\nzer
o-error randomized query complexity was discovered (Ambainis et al.\n15).
This separation is tight and refutes the Saks-Wigderson\nconjecture.\n\n2.
A quartic separation between the deterministic query complexity\nand qua
ntum query complexity was discovered (Ambainis et al. 15). A\nmatching upp
er bound is later proved based on Huang's sensitivity\ntheorem (Aaronson e
t al. 20). \n\n3. The separation between randomized and quantum query com
plexity\nwas improved from quadratic to cubic (Aaronson et al. 15\, Tal 19
\,\nBansal-Sinha 20\, Sherstov et al. 20). A quartic upper bound follows\n
from the above item (Aaronson et al. 20).\n\nIn the seminar\, we will disc
uss these results and the techniques\nbehind them.\n

DESCRIPTION:Topic: Blow up for the energy super critical defocusing NLS\n\n
Speakers: Pierre Raphaël\n\nAffiliation: University of Cambridge\n\nThe d
efocusing Non Linear Schrödinger equation $iu_{t} = \Delta\n{u-u}|u|^{p-1}
$ is a classical model of mathematical physics. For\nenergy subcritical no
n linearities\, Ginibre and Velo proved in the\n’80s that all solutions ar
e global in time and asymptotically behave\nlike linear waves\, and this w
as extended to the energy critical range\nin Bourgain’s breakthrough work
in 1994. But the proof cannot\naddress the energy super critical case for
which global existence vs\nsingularity formation is a classical problem in
the field. I will\nexplain in this lecture the construction of new unexpe
cted highly\noscillatory blow up mechanisms in a suitable energy super cri
tical\nrange of parameters as recently obtained in collaboration with Merl
e\n(IHES)\, Rodnianski (Princeton)\, and Szeftel (Sorbonne). The\nconstruc
tion is deeply connected to the first description of viscous\nthree dimens
ional compressible shock waves in fluid mechanics.\n

DESCRIPTION:Topic: First order rigidity of high-rank arithmetic groups\n\nS
peakers: Alexander Lubotzky\n\nAffiliation: Hebrew University of Jerusalem
\; Visiting Professor\, School of Mathematics\n\nThe family of high-rank a
rithmetic groups is a class of groups playing\nan important role in variou
s areas of mathematics.\n\nIt includes $\mathrm{SL}(n\,\mathbb Z)$\, for $
n > 2$ \, $\mathrm{SL}(n\,\n\mathbb Z[1/p])$ for $n > 1$\, their finite in
dex subgroups and many\nmore.\n\nA number of remarkable results about them
have been proven including\;\nMostow rigidity\, Margulis Super rigidity a
nd the Quasi-isometric\nrigidity.\n\nWe will talk about a new type of rigi
dity: 'first-order rigidity'.\nNamely\, if $G$ is such a non-uniform chara
cteristic zero arithmetic\ngroup and $H$ is a finitely generated group whi
ch is elementary\nequivalent to it then $H$ is isomorphic to $G$.\n\nThis
stands in contrast with Zlil Sela's remarkable work which implies\nthat th
e free groups\, surface groups and hyperbolic groups (many of\nwhich are l
ow-rank arithmetic groups) have many non-isomorphic\nfinitely generated gr
oups which are elementary equivalent to them.\n\nBased on a joint paper wi

e Chassé\, Leo Digiosia\, Rima Chatterjee\n\nAffiliation: University of Mo
ntreal\; Rice University\; University of Cologne\n\nJEAN-PHILIPPE CHASSÉ (
UDEM)\n\nTITLE: Convergence and Riemannian bounds on Lagrangian submanifol
ds\n\nABSTRACT: Recent years have seen the appearance of a plethora of\npo
ssible metrics on spaces of Lagrangian submanifolds. Indeed\, on top\nof t
he better-known Lagrangian Hofer metric and spectral norm\, Biran\,\nCorne
a\, and Shelukhin have constructed families of so-called weighted\nfragmen
tation metrics on these spaces. I will explain how — under\nthe presence o
f bounds coming from Riemannian geometry — all these\nmetrics behave well
with respect to the set-theoretic Hausdorff\nmetric.\n\nLEO DIGIOSIA (RICE
)\n\nTITLE: Cylindrical contact homology of links of simple singularities
\n\nABSTRACT: In this talk we consider the links of simple singularities\,
\nwhich are contactomoprhic to $S^3/G$ for finite subgroups $G$ of\n$SU(2\
,C)$. We explain how to compute the cylindrical contact homology\nof $S^3/
G$ by means of perturbing the canonical contact form by a\nMorse function
that is invariant under the corresponding rotation\nsubgroup. We prove tha
t the ranks are given in terms of the number of\nconjugacy classes of $G$\
, demonstrating a form of the McKay\ncorrespondence. We also explain how o
ur computation realizes the\nSeifert fiber structure of these links.\n\nRI
MA CHATTERJEE (COLOGNE)\n\nTITLE: Cabling of knots in overtwisted contact
manifolds\n\nABSTRACT: Knots associated to overtwisted manifolds are less
explored.\nThere are two types of knots in an overtwisted manifold – loose
and\nnon-loose. Non-loose knots are knots with tight complements whereas
\nloose knots have overtwisted complements. While we understand loose\nkno
ts\, non-loose knots remain a mystery. The classification and\nstructure p
roblems of these knots vary greatly compared to the knots\nin tight manifo
lds. Especially we are interested in how satellite\noperations on a knot i
n overtwisted manifold changes the geometric\nproperty of the knot. In thi
s talk\, I will discuss under what\nconditions cabling operation on a non-
loose knot preserves\nnon-looseness. This is a joint work with Etnyre\, Mi
n and Mukherjee.\n

DESCRIPTION:Topic: The Complexity of Gradient Descent: CLS = PPAD ∩ PLS\n\n
Speakers: Alexandros Hollender\n\nAffiliation: University of Oxford\n\nWe
consider the problem of computing a Gradient Descent solution of a\ncontin
uously differentiable function f on a bounded convex domain\,\ni.e.\, find
ing a 'point where Gradient Descent terminates'.\nEquivalently\, this corr
esponds to computing a so-called KKT\n(Karush-Kuhn-Tucker) stationary poin
t of f.\n\nWe study this problem in the 'white box' model\, where the func
tion f\nis given in the input\, e.g.\, as an arithmetic circuit. By some\n
standard arguments\, it follows that the problem lies in the\nintersection
of the complexity classes PPAD and PLS. PPAD is mostly\nknown for capturi
ng the complexity of computing a Nash equilibrium\,\nwhile PLS has been su
ccessful in characterizing the complexity of\nvarious local optimization p
roblems\, such as Local-Max-Cut.\n\nWe prove that the Gradient Descent pro
blem is complete for PPAD ∩\nPLS. In particular\, this implies that the cl
ass CLS ('Continuous Local\nSearch') which was previously thought to be a
strict subset of PPAD\n∩ PLS\, is in fact equal to it.\n

DESCRIPTION:Topic: First-order rigidity\, bi-interpretability\, and congrue

ithmetic group using its congruence quotients. When this method\nworks\, i
t gives a strong form of first-order rigidity together with a\ncomplete de
scription of the collection of definable subsets in the\ngroup. I'll menti
on two cases where this method works: one is for\nuniform lattices in orth
ogonal groups (which are\, therefore\,\nfirst-order rigid)\; the other is
for families of arithmetic groups.\nOne corollary is that there is a first
-order statement that holds in a\nfinitely generated group if and only if
this group is isomorphic to a\ngroup of the form $SL(n\,A)$\, where $n$ is
at least 3 and $A$ is a ring\nof integers in a number field. This is join

DESCRIPTION:Topic: Results on abundance of global surfaces of section\n\nSp
eakers: Umberto Hryniewicz\n\nAffiliation: RWTH Aachen University\n\nOne m
ight ask if global surfaces of section (GSS) for Reeb flows in\ndimension
3 are abundant in two different senses. One might ask if GSS\nare abundant
for a given Reeb flow\, or if Reeb flows carrying some GSS\nare abundant
in the set of all Reeb flows. In this talk\, answers to\nthese two questio
ns in specific contexts will be presented. First\, I\nwould like to discus
s a result\, obtained in collaboration with Florio\,\nstating that there a
re explicit sets of Reeb flows on $S^3$ which are\nright-handed in the sen
se of Ghys\; in particular\, for such a flow all\nfinite (non-empty) colle
ctions of periodic orbits spans a GSS. Then\, I\nwould like to discuss gen
ericity results\, obtained in collaboration\nwith Colin\, Dehornoy and Rec
htman\, for Reeb flows carrying a GSS\; as a\nparticular case of such resu
lts\, we prove that a $C^\infty$-generic\nReeb flow on the tight 3-sphere
carries a GSS.

DESCRIPTION:Topic: Sharp matrix concentration inequalities\n\nSpeakers: Ram
on van Handel\n\nAffiliation: Princeton University\n\nWhat does the spectr
um of a random matrix look like when we make no\nassumption whatsoever abo
ut the covariance pattern of its entries? \nIt may appear hopeless that an
ything useful can be said at this level\nof generality. Nonetheless\, a wi
dely used set of tools known as\n'matrix concentration inequalities' makes
it possible to estimate at\nleast the spectral norm of very general rando
m matrices up to\nlogarithmic factors in the dimension. On the other hand\
, it is well\nknown that these inequalities fail to yield sharp results fo
r even the\nsimplest random matrix models.\n\nIn this talk I will describe
a powerful new class of matrix\nconcentration inequalities that achieve o
ptimal results in many\nsituations that are outside the reach of classical
methods. Our\nresults are easily applicable in concrete examples\, and yi
eld detailed\nnonasymptotic information on the full spectrum of essentiall
y\narbitrarily structured random matrices. These new inequalities arise\nf
rom an unexpected phenomenon: the spectrum of random matrices is\naccurate
ly captured by certain predictions of free probability theory\nunder surpr
isingly minimal assumptions. Our proofs quantify the notion\nthat it costs
little to be free.\n\nThe talk is based on joint works with Afonso Bandei
ra and March\nBoedihardjo\, and with Tatiana Brailovskaya. No prior backgr
ound will\nbe assumed.\n\n \n

DESCRIPTION:Topic: Contractibility of the space of tight contact structures
on R^3\n\nSpeakers: Yakov Eliashberg\n\nAffiliation: Stanford University\
; Member\, School of Mathematics\n\n30 years ago I proved that any tight c
ontact structure on the 3-sphere\nis diffeomorphic to the standard one. I
also optimistically claimed at\nthe same paper that similar methods could
be used to prove a\nmulti-parametric version: the space of tight contact s
tructures on the\n3-sphere\, fixed at a point\, is contractible. In our re
cent joint with\nN. Mishachev paper we proved this result. While the proof
indeed\nroughly follows the strategy of my 1991 paper\, it is much more\n
involved. In particular\, it uses a new criterion for tightness of a\nchar
acteristic foliation on the 2-sphere\, which is valid without any\ncontact
convexity assumptions.\n

\nAfter surveying some important consequences of the property of bounded\n
generation (BG) dealing with SS-rigidity\, the congruence subgroup\nproble
m\, etc.\, we will focus on examples of boundedly generated\ngroups. We wi
ll prove that every unimodular $(n \times n)$-matrix with\n$n \geq 3$ is a
product of a bounded number of elementaries\n(Carter-Keller) which yields
(BG) for $SL_n(\mathbb{Z})$ $(n \geq 3)$.\nNext\, we will present a geome
tric method for proving (BG) for\n$S$-arithmetic subgroups of orthogonal g
roups (Erovenko-R.) which\napplies also to some other groups of classical
types. Time permitting\,\nwe will also discuss the non-example\, due to W.
van der Kallen\, that\n$SL_n(\mathbb{C}[x])$ is not a bounded product of
elementaries.

DESCRIPTION:Topic: Existence of an unbounded nodal hypersurface for smooth
Gaussian fields in dimension d > 2\n\nSpeakers: Hugo Duminil-Copin\n\nAffi
liation: Institut des Hautes Études Scientifiques\n\nFor the Bargmann--Foc
k field on $R^d$ with $d > 2$\, we prove that the\ncritical level $l_c(d)$
of the percolation model formed by the\nexcursion sets $\{ f \ge l \}$ is
strictly positive. This implies that\nfor every l sufficiently close to 0
(in particular for the nodal\nhypersurfaces corresponding to the case $l=
0$)\, $\{ f = l \}$ contains\nan unbounded connected component that visits
'most' of the ambient\nspace. Our findings (joint work with A. Rivera\, P
F Rodriguez\, and H.\nVanneuville) actually hold for a more general class
of positively\ncorrelated smooth Gaussian fields with rapid decay of corre
lations. A\nconsequence of this result combined with a result of A. Rivera
is that\nMonochromatic Random Wave in high dimensions percolates almost s

DESCRIPTION:Topic: Looking at Euler flows through a contact mirror: Univers
ality\, Turing completeness and undecidability\n\nSpeakers: Eva Miranda\n
\nAffiliation: Universitat Politècnica de Catalunya\n\nAbstract: The dynam
ics of an inviscid and incompressible fluid flow on\na Riemannian manifold
is governed by the Euler equations. Recently\,\nTao [6\, 7\, 8] launched
a programme to address the global existence\nproblem for the Euler and Nav
ier-Stokes equations based on the concept\nof universality. Inspired by th
is proposal\, we show that the\nstationary Euler equations exhibit several
universality features\, in\nthe sense that\, any non-autonomous flow on a
compact manifold can be\nextended to a smooth stationary solution of the
Euler equations on\nsome Riemannian manifold of possibly higher dimension
[1]. \n\nA key point in the proof is looking at the h-principle in contact
\ngeometry through a contact mirror\, unveiled by Etnyre and Ghrist in\n[4
] more than two decades ago.\nWe end this talk addressing a question raise
d by Moore in [5] : “Is\nhydrodynamics capable of performing computations?
”. The universality\nresult above yields the Turing completeness of the st
eady Euler flows\non a 17-dimensional sphere. Can this result be improved?
In [2] we\nconstruct a\nTuring complete steady Euler flow in dimension 3.
Time permitting\, we\ndiscuss this and other generalizations for t-depend
ent Euler flows\ncontained in [3].\n\nIn all the constructions above\, the
metric is seen as an additional\n'variable' and thus the method of proof
does not work if the metric is\nprescribed.\n\nIs it still possible to con
struct a Turing complete Euler flow on a\n3-dimensional space with the sta
ndard metric? See the talk of Daniel\nPeralta-Salas in this workshop.\n\nT

DESCRIPTION:Topic: Parallel Repetition for the GHZ Game: A Simpler Proof\n
\nSpeakers: Uma Girish\n\nAffiliation: Princeton University\n\nWe give a n
ew proof of the fact that the parallel repetition of the\n(3-player) GHZ g
ame reduces the value of the game to zero polynomially\nquickly. That is\
, we show that the value of the n-fold parallel\nrepetition of the GHZ gam
e is at most n^{-\Omega(1)}. This was first\nestablished by Holmgren and
Raz [HR20]. We present a new proof of\nthis theorem that we believe to be
simpler and more direct. Unlike\nmost previous works on parallel repetiti
on\, our proof makes no use of\ninformation theory and relies on the use o
f Fourier analysis. The\nGHZ game [GHZ89] has played a foundational role
in the understanding\nof quantum information theory\, due in part to the f
act that quantum\nstrategies can win the GHZ game with probability 1. It
is possible\nthat improved parallel repetition bounds may find application
s in this\nsetting. Recently\, Dinur\, Harsha\, Venkat\, and Yuen [DHVY17]
\nhighlighted the GHZ game as a simple three-player game\, which is in\nso
me sense maximally far from the class of multi-player games whose\nbehavio
r under parallel repetition is well understood. Dinur et al.\nconjectured
that parallel repetition decreases the value of the GHZ\ngame exponential
ly quickly\, and speculated that progress on proving\nthis would shed ligh
t on parallel repetition for general multi-player\n(multi-prover) games.
\n\nThis is based on a joint work with Justin Holmgren\, Kunal Mittal\, Ra
n\nRaz\, and Wei Zhan.\n

DESCRIPTION:Topic: Mather-Thurston’s theory\, non abelian Poincare duality
and diffeomorphism groups\n\nSpeakers: Sam Nariman\n\nAffiliation: Purdue
University\n\nAbstract: I will discuss a remarkable generalization of Math
er’s\ntheorem by Thurston that relates the identity component of\ndiffeomo
rphism groups to the classifying space of Haefliger\nstructures. The homot
opy type of this classifying space played a\nfundamental role in foliation
theory. However\, it is notoriously\ndifficult to determine its homotopy
groups. Mather-Thurston theory\nrelates the homology of diffeomorphism gro
ups to these homotopy\ngroups. Hence\, this h-principle type theorem has b
een used as the main\ntool to get at the homotopy groups of Haefliger spac
es. We talk about\ngeneralizing Thurston's method to prove analogue of MT
for other\nsubgroups of diffeomorphism groups that was conjectured to hold
. Most\nh-principle methods use the local statement for open ball M=R^n to
\nprove a statement about compact manifolds. Thurston’s method unlike\nthe
later proof by McDuff-Segal has not been widely used. The\ninteresting po
int about Thurston's original method is it is\nintrinsically compactly sup
ported method and it is suitable when the\nlocal statement for M=R^n is ha
rd to prove e.g. Mather-Thurston’s\ntheory for contactomorphism\, foliatio
n preserving diffeomorphisms etc.\n

DESCRIPTION:Topic: Introduction to Continuous Combinatorics I: the semidefi
nite method of flag algebras\n\nSpeakers: Leonardo Coregliano\n\nAffiliati
on: Member\, School of Mathematics\n\nThe field of continuous combinatoric
s studies large (dense)\ncombinatorial structures by encoding them in a 'c
ontinuous' limit\nobject\, which is amenable to tools from analysis\, topo
logy\, measure\ntheory\, etc. The syntactic/algebraic approach of 'flag al
gebras'\n(Razborov '07) to the subject has gained considerable attention i
n the\nlast years due to its applications to extremal combinatorics. More
\nspecifically\, the semidefinite method of flag algebras provides a\nhier
archy of semidefinite programs whose optimal values provide\nasymptotic up
per bounds to any extremal combinatorics problem on\nmaximization of a pol
ynomial function of sub-object densities.\nFurthermore\, even though the o
nly theoretical guarantee is that the\nsemidefinite upper bounds converge
to the true extremal value\, in\nseveral extremal combinatorial problems c
onsidered in the literature a\nvery low level of the hierarchy provides no
t only tight bounds but\nalso structural information about extremality.\n
\nIn the lecture\, I will give an introduction to the theory of flag\nalge
bras and its semidefinite method.\n

DESCRIPTION:Topic: Hamiltonian geometry behind compressible fluids\n\nSpeak
ers: Boris Khesin\n\nAffiliation: University of Toronto\n\nABSTRACT: We de
scribe a geometric framework to study Newton's\nequations on infinite-dime
nsional configuration spaces of\ndiffeomorphisms and smooth probability de
nsities. It turns out that\nseveral important PDEs of hydrodynamical origi
n can be described in\nthis framework in a natural way. In particular\, th
e so-called Madelung\ntransform between the Schrödinger-type equations on
wave functions\nand Newton's equations on densities turns out to be a Kähl
er map\nbetween the corresponding phase spaces\, equipped with the Fubini-
Study\nand Fisher-Rao information metrics. This is a joint work with\nG.Mi
siolek and K.Modin.\n

DESCRIPTION:Topic: A Controlled Mather Thurston Theorem\n\nSpeakers: Mike F
reedman\n\nAffiliation: Microsoft\n\nAbstract: The 'c-principle' is a cous
in of Gromov's h-principle in\nwhich cobordism rather than homotopy is req
uired to (canonically)\nsolve a problem. We show that for the MT-theorem\
, when the base\ndimensions is not equal four\, only the mildest cobordism
s\,\nsemi-s-cobordisms\, are required. In a physical context\, the extra\n
topology (a perfect fundamental group) these cobordisms introduce\ncould b
e hidden in the UV\, suggesting that the action for gauge\ntheories might
be formulated in terms of group extensions and flat\nconnections\, rather
than curvature. See arXiv:2006.00374 for some\npreliminary results.\n

: Let f be an embedding of a non compact manifold into an\nEuclidean space
and p_n be a divergent sequence of points of M. If the\nimage points f(p_
n) converge\, the limit is called a limit point of f.\nIn this talk\, we w

DESCRIPTION:Topic: A topological view on the Monge-Ampere equation without
convexity assumptions\n\nAffiliation: University of Leipzig\n\nAbstract: I
n this talk we consider the classical Monge-Amp´ere\nequation in two dimen
sions in a low-regularity regime:\n\n(0.1) det D 2u = f on D ⊂ R2 .\n\nWe
will assume that f is a given strictly positive\, smooth function\,\nbut w
e want to assume as little regularity as possible on u. For\ninstance we a
re interested in the situation u ∈ C1\, 1/2. In\nparticular we don’t make
any assumptions on the convexity of u.\n\nFirst we will recall shortly how
(0.1) can interpreted under these\nassumptions from a topological point o
f view. Thereafter we will give\nan idea how this information can be trans
formed into a regularity\nresults of u i.e. that it (or −u) coincides with
the classical\nAlexandrov solution.\n\nIf time permits we will report on
its consequence for the rigidity of\nvery weak solutions to the two-dimens
ional Monge-Amp ´ere equation\nand two-dimensional isometric embeddings.\n
\nThe talk is about work in progress.\n

DESCRIPTION:Topic: Ampleness up to avoidance\n\nSpeakers: Alvaro del Pino G
omez \n\nAffiliation: University of Utrecht\n\nABSTRACT: In the first half
of the talk I will review Gromov's work on\nconvex integration for open d
ifferential relations. I will put\nparticular emphasis on comparing variou
s flavours of ampleness and\, in\nparticular\, I will note that the differ
ent flavours require slightly\ndifferent implementations of convex integra
tion.\n\nIn the second half of the talk I will explain some recent joint w
ork\nwith F.J. Martínez Aguinaga: We define a notion of 'ampleness up to\n
avoidance' and we prove that convex integration applies to open\nrelations
satisfying it. Our main example is the differential relation\ndefining hy
perbolic (4\,6)-distributions: it is not ample in the\nclassic sense\, but
it is ample up to avoidance and thus abides by the\nh-principle.\n

DESCRIPTION:Topic: Flexibility in C^0 symplectic geometry\n\nSpeakers: Lev
Buhovsky\n\nAffiliation: Tel Aviv University\n\nAbstract: Traditionally\,
objects of study in symplectic geometry are\nsmooth - such as symplectic a
nd Hamiltonian\ndiffeomorphisms\, Lagrangian (or more generally\, isotropi
c and\nco-isotropic) submanifolds etc. However\, in the course of developm
ent\nof the field\, non-smooth objects or features still appeared - such a
s\nthe Poincaré-Birkhoff theorem about fixed points of an\narea-preserving
homeomorphism of the 2-dim annulus satisfying the\ntwist condition\, or t
he Eliashberg-Gromov theorem about uniform limits\nof symplectic diffeomor
phisms.\n\nA recent attempt for a more systematic approach led to the appe
arance\nof the subfield named C^0 symplectic geometry. C^0 symplectic geom
etry\ntypically studies continuous counterparts of (smooth) symplectic\nob
jects as well as their behaviour under uniform limits. It turned out\nthat
symplectic and Hamiltonian homeomorphisms are flexible in\nsurprising way
s when we are in higher dimensions. \n\nOne of the key ingredients used fo
r showing these flexibility\nphenomena\, is a version of the classical h-p
rinciple of\nEliashberg-Gromov. \n\nIn my talk\, I will give an overview o
f the relevant topics from C^0\nsymplectic geometry.\n

s for\nconstructing the above rational curves. The first is local symplect

orm can be any non-exact 1-form. Moreover\, each connected\ncomponent of t
he boundary\, if any\, may be chosen to be concave or\nconvex and to inher

ension one foliations\, a leafwise locally\nconformal symplectic structure
whose Lee form coincides with the\nholonomy 1-form of the foliation yield
s a contact structure.\nUnfortunately\, the h-principle described above do
es not admit a\nfoliated version\, unless the ambient manifold has a non-e
mpty boundary\nthat intersects all the leaves (plus some other rather natu
ral\nconditions). This is a joint work with Gaël Meigniez.\n

ev\n\nAffiliation: University of Massachusetts\, Boston\n\nAbstract: Cieli
ebak and Eliashberg showed that there is a special\nclass of flexible symp
lectic structures that satisfy an h-principle\nand hence have `trivial' s
ymplectic topology. In this talk\, I will\nexplain that it is fruitful to
think of flexibilization as a \nlocalization functor of the category of sy
mplectic manifolds. In\nparticular\, I will show that for any collection o
f primes P\, there is\na `P-flexibilization' functor that cannot satisfy a
n h-principle but\nis still localizing (after inverting subcritical handle
s and\nstabilizing)\, with usual flexibilization corresponding to the `pri
me'\n0. This is a symplectic analog of the localization of classical\ntopo
logical spaces studied by Quillen\, Sullivan\, and others. \n\nThis talk i

DESCRIPTION:Topic: The Kakeya Set conjecture over Z mod N for general N\n\n
Speakers: Manik Dhar\n\nAffiliation: Princeton University\n\nA Kakeya Set
in (Z/N Z)^n is a set that contains a line in every\ndirection. It has be
en known for over a decade that such sets must\nbe large when N is prime (
or more generally over any finite field). \nThis goes back to Dvir's proof
of the finite field Kakeya conjecture\nas posed by Wolff. In this talk I
will cover results from three papers\nfrom the past ~year culminating in t
he resolution of the conjecture\nfor any N\, showing that\, for every eps>
0\, a Kakeya set S in (Z/N Z)^n\nmust have size at least C*N^{n-eps} where
the constant C depends on n\nand eps only. The first paper (by the speake
r and Dvir) resolved the\ncase of square-free N. The second paper (by Ars
ovski) settled the\nprime power case (which implies the p-adic Kakeya conj
ecture for\nHausdorff dimension). Finally\, a paper by the speaker\, buil
ding on\nideas from both prior works\, proves the conjecture for any N. T
he\nproofs involve several extensions/modifications to the polynomial\nmet
hod (as used by Dvir for the finite field case) which may be of\nindepende
nt interest.\n\n \n

DESCRIPTION:Topic: Introduction to Continuous Combinatorics II: semantic li
mits\n\nSpeakers: Leonardo Coregliano\n\nAffiliation: Member\, School of M
athematics\n\nThe field of continuous combinatorics studies large (dense)
\ncombinatorial structures by encoding them in a 'continuous' limit\nobjec
t\, which is amenable to tools from analysis\, topology\, measure\ntheory\
, etc. While the syntactic/algebraic approach of 'flag algebras'\n(Razboro
v '07) provides a very simple limit object for convergent\nsequences\, the
minimalist nature of the limit objects from flag\nalgebras loses almost a
ll information on the semantics and geometry of\nthe original objects. On
the other side of the coin\, the\ngeometric/semantic approach to the subje
ct\, typically associated with\nthe name 'graphons' (Lovász--Szegedy '04)
for limits of graphs and\nwith the name 'theons' (C.--Razborov '20) for li
mits of arbitrary\ncombinatorial objects\, retains geometric and semantic
information by\nproducing a more complicated limit that still 'looks like'
the\noriginal objects.\n\nIn this lecture\, I will give an introduction t
o the theories of\ngraphons and theons and show some examples of theorems
in the theory\nof quasirandomness that greatly benefit from either a\nsema
ntic/geometric approach or from a hybrid approach.\n

s: William Yun Chen\n\nAffiliation: Member\, School of Mathematics\n\nSome
how\, despite the title\, $SL(2\,Z)$ is the poster child for\narithmetic g
roups not satisfying the congruence subgroup property\,\nwhich is to say t
hat it has finite index subgroups which can not be\ndefined by congruence
conditions on their coefficients. The existence\nof such noncongruence sub
groups is reflective of the dual nature of\n$SL(2\,Z)$ as both the mapping
class group of a torus\, as well as that\nof a once punctured torus. This
coincidence\, however innocuous at\nfirst sight\, leads to quickly diverg
ing theories\, the difference being\nakin to the distinction between surfa
ces of genus 1 vs genus $\geq 2$\nin geometry. In the first part of the ta
lk\, I will explain how in the\nlatter perspective\, $SL(2\,Z)$ actually s
atisfies a 'congruence\nsubgroup property' (in a necessarily different sen
se!)\, and how this\nproperty leads to a natural procedure that takes as i
nput a\ntopological covering $X$ of a punctured torus $T$\, and produces a
s\noutput a finite index subgroup of $SL(2\,Z)$. Moreover\, almost every\n
finite index subgroup can be constructed in this way. Geometrically\,\non
input $X/T$\, the output is the fundamental group of the moduli\nstack of
covers of punctured elliptic curves which are topologically\nisomorphic to
$X/T$. I will also explain this procedure in terms of\ngroup theory\, and
in terms of Teichmuller dynamics. I will describe\nsome results and natur
al questions that arise\, using the congruence\ncase as an example. While
there is a simple algorithm for carrying out\nthe above procedure\, it is
difficult to predict properties of the\noutput given knowledge of the inpu
t. In the second part of the talk\, I\nwill describe a new result in this
direction. If the input is a cover\n$X/T$ which is Galois with all ramific
ation indices above the puncture\nequal to e\, then under certain conditio
ns the output will have index\ndivisible by e. Using the character variety
for\n$SL(2)$-representations of $\pi_1(T)$\, I will explain how this impl
ies\na conjecture of Bourgain\, Gamburd\, and Sarnak on the arithmetic of
the\nMarkoff surface $x^2 + y^2 + z^2 - xyz = 0$. This also leads to an\ne
xplicit genus formula for a certain family of noncongruence modular\ncurve
s\, and a formula for the Siegel-Veech constants of a certain\nnatural fam
ily of square-tiled congruence modular curves.\n

ies which is\nalso a meromorphic function in some neighborhood of the orig
in. The\nsubject of the talk will be how certain conditions on $f(x)$ as a
\nmeromorphic function actually guarantee that $f(x)$ is an algebraic\nfun

DESCRIPTION:Topic: Stable Vortex Sheets and Irreversibility of Turbulence\n
\nSpeakers: Alexander Migdal\n\nAffiliation: New York University\n\nNew ki
nds of vortex sheets with vorticity confined to the boundary\nlayer are pr
oposed and investigated in detail. Exact solutions of the\nsteady Navier-S
tokes equations for a planar vortex sheet in arbitrary\nbackground strain
are found in terms of hypergeometric functions.These\nsolutions are stable
only under certain conditions on background\nstrain.\n\nThe stability con
ditions (CVS equations) reduce to vanishing component\nof the local strain
in the direction of the velocity gap\, in addition\nto the usual requirem
ent of vanishing normal velocity on each side.\nThe normal component of th
e strain must be negative for stability\,\nwhich is the origin of an irrev
ersibility of Turbulence in our theory.\n\nAnomalous energy dissipation (s
urface enstrophy) is conserved on CVS\nvortex sheets in the Navier-Stokes
equation.\n\nThe CVS equations serve as boundary conditions to the Euler e
quations\nand also determine the shape of the surface up to a few paramete
rs.\nThese parameters are the eigenvalues of the background strain plus\nl
ocation and rotation matrix.\n\nWe argue that this background strain is a
random gaussian symmetric\ntraceless matrix with the calculable distributi
on of eigenvalues. The\nvariance of this Gaussian tensor is related to the
energy dissipation\nby self-consistency equations of mean-field theory.\n
\nThe fluctuating ratio of eigenvalues leads to multifractal properties\no
f the vortex surface\, offering a possible explanation of the\nmultifracta
l scaling laws for velocity differences in extreme\nturbulence.\n\nThe ano
malous energy dissipation has a universal probability\ndistribution in our
theory\, which is calculated numerically.\n

Chaidez\n\nAffiliation: Princeton University\; Visitor\, School of Mathem
atics\n\nIn this talk\, I will define the Ruelle invariant of a measure\np
reserving flow equipped with a symplectic cocycle. This is a natural\ndyna
mical quantity that measures a spacetime averaged rotation of the\ncocycle
along the flow. I will then discuss the examples that show up\nin Hamilto
nian and Reeb dynamics. Finally\, for the Reeb flow on a\nconvex hypersurf
ace\, I will derive estimates for the Ruelle invariant\nin terms of the to
tal mean curvature of the convex hypersurface.\n
