 /">Analytic Number Theory and Optimal Transport: an interesting connection
 </a>\nby Stefan Steinerberger (University of Washington) as part of Rutger
 s Number Theory Seminar\n\n\nAbstract\nOptimal Transport studies the probl
 em of how to move one measure to another so that the "transport cost" is m
 inimal.  Think of one measure being products in a warehouse and the other 
 measure being how much people want to buy the product: the transport dista
 nce would then be the amount of miles trucks have to drive (weighted by ho
 w much they carry).  I will start by giving a gentle Introduction to this 
 topic\, we do not actually need very much.  My question then is: suppose o
 ne measure is the normalized counting measure in quadratic residues in a f
 inite field and the other is the uniform measure\, can the Transport be es
 timated?  Or maybe Dirac measures placed in irrational rotations on the To
 rus: how cheap is it to transport them to the Lebesgue measure?  And are t
 hese results interesting? (Spoiler: yes).  And do they carry some useful m
 eaning? (Spoiler: yes)  Some recent advances in Optimal Transport allow th
 ese problems to be reduced to a simple exponential sum\; basic ingredients
  from Analytic Number Theory can then be used to get new insight at relati
 vely low technical cost.   There are many\, many open questions.\n

 /">Arithmetic and quasi-arithmetic hyperbolic reflection groups</a>\nby Ni
 kolay Bogachev (Skoltech & MIPT) as part of Rutgers Number Theory Seminar\
 n\n\nAbstract\nIn 1967\, Vinberg started a systematic study of hyperbolic 
 reflection groups. In particular\, he showed that Coxeter polytopes are na
 tural fundamental domains of hyperbolic reflection groups and developed pr
 actically efficient methods that allow to determine compactness or volume 
 finiteness of a given Coxeter polytope by looking at its Coxeter diagram. 
 He also proved a (quasi-)arithmeticity criterion for hyperbolic lattices g
 enerated by reflections. In 1981\, Vinberg showed that there are no compac
 t Coxeter polytopes in hyperbolic spaces H^n for n>29. Also\, he showed th
 at there are no arithmetic hyperbolic reflection groups H^n for n>29\, eit
 her. Due to the results of Nikulin (2007) and Agol\, Belolipetsky\, Storm\
 , and Whyte (2008) it became known that there are only finitely many maxim
 al arithmetic hyperbolic reflection groups in all dimensions. These result
 s give hope that maximal arithmetic hyperbolic reflection groups can be cl
 assified.\n\n \nA very interesting moment is that compact Coxeter polytope
 s are known only up to H^8\, and in H^7 and H^8 all the known examples are
  arithmetic. Thus\, besides the problem of classification of arithmetic hy
 perbolic reflection groups (which remains open since 1970-80s) we have ano
 ther very natural question (which is again open since 1980s): do there exi
 st compact (both arithmetic and non-arithmetic) hyperbolic Coxeter polytop
 es in H^n for n>8 ?\n \n\nThe talk will be devoted to the discussion of th
 ese two related problems. One part of the talk is based on the recent prep
 rint https://arxiv.org/abs/2003.11944v2 where some new geometric classific
 ation method is described. The second part is based on a joint work with A
 lexander Kolpakov https://arxiv.org/abs/2002.11445v2 where we prove that e
 ach lower-dimensional face of a quasi-arithmetic Coxeter polytope\, which 
 happens to be itself a Coxeter polytope\, is also quasi-arithmetic. We als
 o provide a few illustrative examples.\n

 ersity of Cambridge) as part of Rutgers Number Theory Seminar\n\n\nAbstrac
 t\nHow much additive structure can we guarantee in sets of integers\, know
 ing only their density? The study of which density thresholds are sufficie
 nt to guarantee the existence of various kinds of additive structures is a
 n old and fascinating subject with connections to analytic number theory\,
  additive combinatorics\, and harmonic analysis.\n\nIn this talk we will d
 iscuss recent progress on perhaps the most well-known of these thresholds:
  how large do we need a set of integers to be to guarantee the existence o
 f a three-term arithmetic progression? In recent joint work with Olof Sisa
 sk we broke through the logarithmic density barrier for this problem\, est
 ablishing in particular that if a set is dense enough such that the sum of
  reciprocals diverges\, then it must contain a three-term arithmetic progr
 ession\, establishing the first case of an infamous conjecture of Erdos.\n
 \nWe will give an introduction to this problem and sketch some of the rece
 nt ideas that have made this progress possible. We will also discuss a rec
 ent application to the density threshold of a set containing no square dif
 ferences.\n

 rt of Rutgers Number Theory Seminar\n\n\nAbstract\nLanglands functoriality
  predicts maps between automorphic representations on different groups\, d
 ictated by a map of L-groups. One important class of such maps are endosco
 pic liftings\, established by Arthur using the trace formula. In this talk
  I describe an approach to endoscopic lifting that does not use the trace 
 formula. Instead it follows the approach of Cogdell\, Kim\, Piatetski-Shap
 iro and Shahidi\, who handled (before Arthur) the case of endoscopic lifti
 ngs of generic automorphic representations by studying L-functions and usi
 ng the converse theorem.  Using a new integral representations of L-functi
 ons of Cai\, Friedberg\, Ginzburg and Kaplan\, I and my collaborators are 
 able to handle all cuspidal automorphic representations\, and even to give
  some liftings outside the work of Arthur.\n

 y Tony Feng (MIT) as part of Rutgers Number Theory Seminar\n\n\nAbstract\n
 Many interesting aspects of the arithmetic of elliptic curves over global 
 fields are governed by Selmer groups\, which are cohomological approximati
 ons to the group of rational points. The statistical behavior of Selmer gr
 oups has been the focus of much recent study\, and there is a wide gap bet
 ween 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-Selm
 er groups. On the other hand\, Bhargava-Kane-Lenstra-Poonen-Rains conjectu
 re a precise distribution for n-Selmer groups\, for any n. I will talk abo
 ut a limiting situation\, in the function field context\, where the BKLPR 
 distribution can actually be proved to model the distribution of Selmer gr
 oups. This is joint work with Aaron Landesman and Eric Rains.\n

 >\nby Nattalie Tamam (UCSD) as part of Rutgers Number Theory Seminar\n\n\n
 Abstract\nHorospherical flows in homogeneous spaces have been studied inte
 nsively over the last several decades and have many surprising application
 s in various fields. Many basic results are under the assumption that the 
 volume of the space is finite\, which is crucial as many basic ergodic the
 orems fail in the setting of an infinite measure space. In the talk we wil
 l discuss the infinite volume setting\, and specifically\, when can we exp
 ect horospherical orbits to equidistribute. Our goal will be to provide an
  effective equidistribution result\, with polynomial rate\, for horospheri
 cal orbits in the frame bundle of certain infinite volume hyperbolic manif
 olds. This is a joint work with Jacqueline Warren.\n

 ilansky (Rutgers University) as part of Rutgers Number Theory Seminar\n\n\
 nAbstract\nCut-and-project point sets are constructed by identifying a str
 ip of a fixed n-dimensional lattice (the "cut")\, and projecting the latti
 ce points in that strip to a d-dimensional subspace (the "project”)\, an
 d are a well-studied model of aperiodic order. Dynamical results concernin
 g 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 what happe
 ns when instead of restricting to translations we consider all volume pres
 erving linear actions? \n\nA homogenous space of cut-and-project sets is d
 efined by fixing a cut-and-project construction and varying the n-dimensio
 nal 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/abs/2012.1
 3299)\, I will discuss this construction and introduce the class of Ratner
 -Marklof-Strömbergsson measures\, which are probability measures supporte
 d on cut-and-project spaces that are invariant and ergodic for the group a
 ction. A classification of these measures is described in terms of data of
  algebraic groups\, and is used to prove analogues of results about a Sieg
 el summation formula and identities and bounds involving higher moments. T
 hese in turn imply results about asymptotics\, with error estimates\, of p
 oint-counting and patch-counting statistics for typical cut-and-project se

 mZ is called a "perfect difference set" if every nonzero element of Z/mZ c
 an be written uniquely as the difference of two elements of D. If such a s
 et exists\, then a simple counting argument shows that m=n^2+n+1 for some 
 nonnegative integer n. Singer constructed examples of perfect difference s
 ets in Z/(n^2+n+1)Z whenever n is a prime power\, and it is an old conject
 ure that these are the only such n for which a perfect difference set exis
 ts. 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 contains a
  perfect difference set is ~N/log(N).\n

  multiplicative functions like Dirichlet characters or the Mobius function
 . Arguably the first question ever studied about them\, by Wintner in 1944
 \, was to obtain almost sure bounds for the largest fluctuations of their 
 partial $\\sum_{n \\leq x} f(n)$\, seeking to emulate the classical Law of
  the Iterated Logarithm for independent random variables. It remains an op
 en question to sharply determine the size of these fluctuations\, and in t
 his talk I will describe a new result in that direction. I hope to get to

DESCRIPTION:Title: <a href="https://researchseminars.org/talk/RutgersNTS/2
 2/">Arithmetic statistics of modular symbols</a>\nby Yiannis Petridis (Uni
 versity College London) as part of Rutgers Number Theory Seminar\n\n\nAbst
 ract\nThe central value of the L-function of an elliptic curve has been th
 e object of extensive studies in the last 50 years. Associated with such a
  curve we wish to understand also families of twists of it\, leading to th
 e study of twisted L-functions. On the other hand modular symbols have bee
 n a useful tool to study the space of holomorphic cusp forms of weight 2\,
  and the homology of modular curves. They have been the object of extensiv
 e investigations by many mathematicians including Birch\, Manin\, and Crem
 ona. Mazur\, Rubin\, and Stein have recently formulated a series of conjec
 tures about statistical properties of modular symbols in order to understa
 nd central values of twists of elliptic curve L-functions. We discuss some
  of these conjectures and the recent progress and resolution of them. This
  is joint work with M. S. Risager.\n
