DESCRIPTION:Title: Constrained convex bodies with maximal affine surface a
rea\nby Elisabeth Werner (Case Western Reserve University) as part of Onli
ne asymptotic geometric analysis seminar\n\n\nAbstract\nGiven a convex bod
y K in R^n\, we study the maximal affine surface area of K\, i.e.\, the qu
antity AS(K) = sup_{C} as(C) where as(C) denotes the affine surface area o
f C\, and the supremum is taken over all convex subsets of K. In particula
r\, we give asymptotic estimates on the size of AS(K).\n

DESCRIPTION:Title: Metric distortion of random spaces\nby Uri Grupel (Univ
ersity of Innsbruk) as part of Online asymptotic geometric analysis semina
r\n\n\nAbstract\nWe consider a random set in the unit circle. Is the induc
ed discrete metric of the set closer to that of another independent random
set or to the evenly spaced set of the same cardinality? We measure the d
istortion by looking at the smallest bi-Lipschitz norm of all the bijectio
ns between the two sets. Since the distortion between two random sets has
infinite expectation\, the talk will focus on the median. We show that two
random sets have "typically" smaller distortion than a random set and an
evenly spaced set.\n

DESCRIPTION:Title: On the fundamental gap and convex sets in hyperbolic sp
ace\nby Alina Stancu (Concordia University) as part of Online asymptotic g

l gap of the Laplacian on convex domains in R^n\, with Dirichlet boundary
conditions\, has a long history and has been finally settled a few years a
go with parabolic methods by Andrews and Clutterbuck. More recently\, the
same lower bound\, which depends on the diameter of the domain\, has been
proved for convex sets on the standard sphere in several stages with sever
al groups of authors\, 2016-2018. Over the past year\, together with colla
borators\, we have found that the gap on the hyperbolic space behaves stri
kingly different and we aim to explain it\, particularly for this audience
\, as a difference in the nature of convex sets in H^n versus R^n or S^n.\

DESCRIPTION:Title: Rigidity of Riemannian embeddings of discrete metric sp
aces\nby Bo'az Klartag (Weizmann Institute) as part of Online asymptotic g
eometric analysis seminar\n\n\nAbstract\nLet M be a complete\, connected R
iemannian surface and suppose that S is a discrete subset of M. What can w
e learn about M from the knowledge of all distances in the surface between
pairs of points of S? We prove that if the distances in S correspond to t
he distances in a 2-dimensional lattice\, or more generally in an arbitrar
y net in R^2\, then M is isometric to the Euclidean plane. We thus find th
at Riemannian embeddings of certain discrete metric spaces are rather rigi
d. A corollary is that a subset of Z^3 that strictly contains a two-dimens
ional lattice cannot be isometrically embedded in any complete Riemannian
surface. This is a joint work with M. Eilat.\n

(Marne-la-Vallée) as part of Online asymptotic geometric analysis semina

ly-symmetric random polytopes\, generated by $N$ independent copies of a r

deterministic set that is naturally associated with the random vector---n

the class of flowers. A flower in R^n is an arbitrary union of balls whic
h contain the origin. While flowers are not necessarily convex\, they are
in one to one correspond with the class of convex bodies containing the or
igin\, so by studying flowers we are also studying convex bodies from a ne
w viewpoint. We will give several equivalent definitions of flowers and de
scribe some of their basic properties. We will also discuss how to apply a
n arbitrary (real) function to a flower\, and the corresponding constructi
on for convex bodies. In particular\, we will explain how to raise a flowe
r to a given power. Finally\, we will discuss some elements of the asympto
tic theory of flowers. In particular we will present a Dvoretzky-type theo
rem for flowers which actually gives better estimates than the correspondi
ng estimates for convex bodies. Based on two papers by the speakers\, the
first of which is joint with E. Milman.\n

re on translation invariant smooth valuations was introduced by the speake
r years ago. Since then several non-trivial properties of it have been dis
covered as well as a few applications to integral geometry. In the first p
art of the talk we will review some of these properties. Then we discuss a
nalogues of the algebra of even translation invariant valuations over othe
r locally compact (e.g. complex\, p-adic) fields. While any interpretation
of these new algebras is missing at the moment\, their properties seem (t
o the speaker) to be non-trivial and having some intrinsic beauty.\n

DESCRIPTION:Title: Modewise methods for tensor dimension reduction\nby Eli
zaveta Rebrova (UCLA) as part of Online asymptotic geometric analysis semi
nar\n\n\nAbstract\nAlthough tensors are a natural multi-modal extension of
matrices\, going beyond two modes (that is\, rows and columns) presents m
any interesting non-trivialities. For example\, the notion of singular val
ues is no longer well-defined\, and there are various versions of the rank
. One of the most natural (and mathematically challenging) definitions of
the tensor rank is so-called CP-rank: for a tensor X\, it is a minimal num
ber of rank one tensors whose linear combination constitutes X. Main focus
of my talk will be an extension of the celebrated Johnson-Lindenstrauss l
emma to low CP-rank tensors. Namely\, I will discuss how modewise randomiz
ed projections can preserve tensor geometry in the subspace oblivious way
(that is\, a projection model is not adapted for a particular tensor subsp
ace). Modewise methods are especially interesting for the tensors as they
preserve the multi-modal structure of the data\, acting on a tensor direct
ly\, without initial conversion of tensors to matrices or vectors. I will
also discuss an application for the least squares fitting CP model for ten
sors. Based on our joint work with Mark Iwen\, Deanna Needell\, and Ali Za

a (University of Warsaw) as part of Online asymptotic geometric analysis s
eminar\n\n\nAbstract\nI will discuss two-sided bounds for expectations of
order statistics (k-th maxima) of moduli of coordinates of centered log-co
ncave random vectors with uncorrelated coordinates. Our bounds are exact u
p to multiplicative universal constants in the unconditional case for all
k and in the isotropic case for k = n-cn^{5/6}. We also present two-sided
estimates for expectations of sums of k largest moduli of coordinates for
some classes of random vectors. Joint work with Marta Strzelecka.\n

DESCRIPTION:Title: Further inequalities for the Wills functional of convex
bodies\nby Michael Roysdon\, Jesus Yepes Nicolas (Tel Aviv University) as
part of Online asymptotic geometric analysis seminar\n\n\nAbstract\nMicha
el Roysdon\, Tel Aviv University\, Israel\n\nTopic:$L_p$-Brunn-Minkoswki t
ype inequalities and an $L_p$-Borell-Brascamp-Lieb inequality\, 10:30-10:5
0\n\nAbstract: the classical Brunn-Minkowski inequality asserts that the v
olume of convex Minkowski combination exhibits (1/n)-concavity when applie
d for any pair of convex bodies (or more generally\, Borel sets). Many adv
ancements of this inequality have been studied throughout the year\, famou
s examples of such mathematicians who pursued these studies are Prekopa\,
Leindler\, and Brascamp and Lieb. The goal of this talk is to introduce th
e "L_p" versions of such inequalities following the L_p-Minkowski sum intr
oduced by Firey (and later more generally by Lutwak\, Yang\, and Zhang)\,
as well as it's associated L_p_ Brunn-Minkowksi inequality. In particular\
, we show that such inequalities hold in the class of s-concave measures\,
and discuss the related isoperimetric inequality (joint with S. Xing).\n\
nJesús Yepes Nicolás\, Universidad de Murcia\, Spain\n\nTopic: Further i
nequalities for the Wills functional of convex bodies.\n\nAbstract: The Wi
lls functional of a convex body\, defined as the sum of its intrinsic volu
mes\, turned out to have many interesting applications and properties. In
this talk\, making profit of the fact that it can be represented as the in
tegral of a log-concave function\, which is furthermore the Asplund produc
t of other two log-concave functions\, we will show new properties of the
Wills functional. Among others\, we get Brunn-Minkowski and Rogers-Shephar
d type inequalities for this functional and show that the cube of edge-len
gth 2 maximizes it among all 0-symmetric convex bodies in John position. J
oint work with David Alonso-Guti�rrez and Mar�a A. Hern�ndez Cifre.\
