 rsNTS/1/">Analytic Number Theory and Optimal Transport: an interesting con
 nection</a>\nby Stefan Steinerberger (University of Washington) as part of
  Rutgers Number Theory Seminar\n\n\nAbstract\nOptimal Transport studies th
 e problem of how to move one measure to another so that the "transport cos
 t" is minimal.  Think of one measure being products in a warehouse and the
  other measure being how much people want to buy the product: the transpor
 t distance would then be the amount of miles trucks have to drive (weighte
 d by how much they carry).  I will start by giving a gentle Introduction t
 o this topic\, we do not actually need very much.  My question then is: su
 ppose one measure is the normalized counting measure in quadratic residues
  in a finite field and the other is the uniform measure\, can the Transpor
 t be estimated?  Or maybe Dirac measures placed in irrational rotations on
  the Torus: how cheap is it to transport them to the Lebesgue measure?  An
 d are these results interesting? (Spoiler: yes).  And do they carry some u
 seful meaning? (Spoiler: yes)  Some recent advances in Optimal Transport a
 llow these problems to be reduced to a simple exponential sum\; basic ingr
 edients from Analytic Number Theory can then be used to get new insight at
  relatively low technical cost.   There are many\, many open questions.\n

 rsNTS/2/">Arithmetic and quasi-arithmetic hyperbolic reflection groups</a>
 \nby Nikolay Bogachev (Skoltech & MIPT) as part of Rutgers Number Theory S
 eminar\n\n\nAbstract\nIn 1967\, Vinberg started a systematic study of hype
 rbolic reflection groups. In particular\, he showed that Coxeter polytopes
  are natural fundamental domains of hyperbolic reflection groups and devel
 oped practically efficient methods that allow to determine compactness or 
 volume finiteness of a given Coxeter polytope by looking at its Coxeter di
 agram. He also proved a (quasi-)arithmeticity criterion for hyperbolic lat
 tices generated by reflections. In 1981\, Vinberg showed that there are no
  compact Coxeter polytopes in hyperbolic spaces H^n for n>29. Also\, he sh
 owed that there are no arithmetic hyperbolic reflection groups H^n for n>2
 9\, either. Due to the results of Nikulin (2007) and Agol\, Belolipetsky\,
  Storm\, and Whyte (2008) it became known that there are only finitely man
 y maximal arithmetic hyperbolic reflection groups in all dimensions. These
  results give hope that maximal arithmetic hyperbolic reflection groups ca
 n be classified.\n\n \nA very interesting moment is that compact Coxeter p
 olytopes are known only up to H^8\, and in H^7 and H^8 all the known examp
 les are arithmetic. Thus\, besides the problem of classification of arithm
 etic hyperbolic reflection groups (which remains open since 1970-80s) we h
 ave another very natural question (which is again open since 1980s): do th
 ere exist compact (both arithmetic and non-arithmetic) hyperbolic Coxeter 
 polytopes in H^n for n>8 ?\n \n\nThe talk will be devoted to the discussio
 n of these two related problems. One part of the talk is based on the rece
 nt preprint https://arxiv.org/abs/2003.11944v2 where some new geometric cl
 assification method is described. The second part is based on a joint work
  with Alexander Kolpakov https://arxiv.org/abs/2002.11445v2 where we prove
  that each lower-dimensional face of a quasi-arithmetic Coxeter polytope\,
  which happens to be itself a Coxeter polytope\, is also quasi-arithmetic.
  We also provide a few illustrative examples.\n

 m (University of Cambridge) as part of Rutgers Number Theory Seminar\n\n\n
 Abstract\nHow much additive structure can we guarantee in sets of integers
 \, knowing only their density? The study of which density thresholds are s
 ufficient to guarantee the existence of various kinds of additive structur
 es is an old and fascinating subject with connections to analytic number t
 heory\, additive combinatorics\, and harmonic analysis.\n\nIn this talk we
  will discuss recent progress on perhaps the most well-known of these thre
 sholds: how large do we need a set of integers to be to guarantee the exis
 tence of a three-term arithmetic progression? In recent joint work with Ol
 of Sisask we broke through the logarithmic density barrier for this proble
 m\, establishing in particular that if a set is dense enough such that the
  sum of reciprocals diverges\, then it must contain a three-term arithmeti
 c progression\, establishing the first case of an infamous conjecture of E
 rdos.\n\nWe will give an introduction to this problem and sketch some of t
 he recent ideas that have made this progress possible. We will also discus
 s a recent application to the density threshold of a set containing no squ
 are differences.\n

 l representations of L-functions</a>\nby Solomon Friedberg (Boston College
 ) as part of Rutgers Number Theory Seminar\n\n\nAbstract\nLanglands functo
 riality predicts maps between automorphic representations on different gro
 ups\, dictated by a map of L-groups. One important class of such maps are 
 endoscopic liftings\, established by Arthur using the trace formula. In th
 is talk I describe an approach to endoscopic lifting that does not use the
  trace formula. Instead it follows the approach of Cogdell\, Kim\, Piatets
 ki-Shapiro and Shahidi\, who handled (before Arthur) the case of endoscopi
 c liftings of generic automorphic representations by studying L-functions 
 and using the converse theorem.  Using a new integral representations of L
 -functions of Cai\, Friedberg\, Ginzburg and Kaplan\, I and my collaborato
 rs are able to handle all cuspidal automorphic representations\, and even 
 to give some liftings outside the work of Arthur.\n

 </a>\nby Tony Feng (MIT) as part of Rutgers Number Theory Seminar\n\n\nAbs
 tract\nMany interesting aspects of the arithmetic of elliptic curves over 
 global fields are governed by Selmer groups\, which are cohomological appr
 oximations to the group of rational points. The statistical behavior of Se
 lmer groups has been the focus of much recent study\, and there is a wide 
 gap between what we can prove and what we believe is true. On the one hand
 \, work of Bhargava and Shankar computes the average size of 2\,3\,4\, and
  5-Selmer groups. On the other hand\, Bhargava-Kane-Lenstra-Poonen-Rains c
 onjecture a precise distribution for n-Selmer groups\, for any n. I will t
 alk about a limiting situation\, in the function field context\, where the
  BKLPR distribution can actually be proved to model the distribution of Se
 lmer groups. This is joint work with Aaron Landesman and Eric Rains.\n

 r\n\n\nAbstract\nHorospherical flows in homogeneous spaces have been studi
 ed intensively over the last several decades and have many surprising appl
 ications in various fields. Many basic results are under the assumption th
 at the volume of the space is finite\, which is crucial as many basic ergo
 dic theorems fail in the setting of an infinite measure space. In the talk
  we will discuss the infinite volume setting\, and specifically\, when can
  we expect horospherical orbits to equidistribute. Our goal will be to pro
 vide an effective equidistribution result\, with polynomial rate\, for hor
 ospherical orbits in the frame bundle of certain infinite volume hyperboli
 c manifolds. This is a joint work with Jacqueline Warren.\n

 otam Smilansky (Rutgers University) as part of Rutgers Number Theory Semin
 ar\n\n\nAbstract\nCut-and-project point sets are constructed by identifyin
 g a strip of a fixed n-dimensional lattice (the "cut")\, and projecting th
 e lattice points in that strip to a d-dimensional subspace (the "project
 ”)\, and are a well-studied model of aperiodic order. Dynamical results 
 concerning the translation action on the hull of a cut-and-project set are
  known to shed light on certain properties of the point set itself\, but w
 hat happens when instead of restricting to translations we consider all vo
 lume preserving linear actions? \n\nA homogenous space of cut-and-project 
 sets is defined by fixing a cut-and-project construction and varying the n
 -dimensional grid according to an ASL(d\,R) action. In the talk\, which is
  based on joint work with René Rühr and Barak Weiss (https://arxiv.org/a
 bs/2012.13299)\, I will discuss this construction and introduce the class 
 of Ratner-Marklof-Strömbergsson measures\, which are probability measures
  supported on cut-and-project spaces that are invariant and ergodic for th
 e group action. A classification of these measures is described in terms o
 f data of algebraic groups\, and is used to prove analogues of results abo
 ut a Siegel summation formula and identities and bounds involving higher m
 oments. These in turn imply results about asymptotics\, with error estimat
 es\, of point-counting and patch-counting statistics for typical cut-and-p
 roject sets.\n

 roup Z/mZ is called a "perfect difference set" if every nonzero element of
  Z/mZ can be written uniquely as the difference of two elements of D. If s
 uch a set exists\, then a simple counting argument shows that m=n^2+n+1 fo
 r some nonnegative integer n. Singer constructed examples of perfect diffe
 rence sets in Z/(n^2+n+1)Z whenever n is a prime power\, and it is an old 
 conjecture that these are the only such n for which a perfect difference s
 et exists. In this talk\, I will discuss a proof of an asymptotic version 
 of this conjecture: the number of n less than N for which Z/(n^2+n+1)Z con
 tains a perfect difference set is ~N/log(N).\n

 l points are fixed. We will explore the correspondence both in the dynamic
 al plane and the parameter spaces. In particular\, we will explain how the
  analogue of Thurston’s compactness theorem for acylindrical hyperbolic 
 3-manifold holds for critically fixed anti-rational maps.\nWe will also br
 iefly discuss some open questions motivated by the correspondence.\n

DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/Rutge

 n\nAbstract\nThe central value of the L-function of an elliptic curve has 
 been the object of extensive studies in the last 50 years. Associated with
  such a curve we wish to understand also families of twists of it\, leadin
 g to the study of twisted L-functions. On the other hand modular symbols h
 ave been a useful tool to study the space of holomorphic cusp forms of wei
 ght 2\, and the homology of modular curves. They have been the object of e
 xtensive investigations by many mathematicians including Birch\, Manin\, a
 nd Cremona. Mazur\, Rubin\, and Stein have recently formulated a series of
  conjectures about statistical properties of modular symbols in order to u
 nderstand central values of twists of elliptic curve L-functions. We discu
 ss some of these conjectures and the recent progress and resolution of the
 m. This is joint work with M. S. Risager.\n
