Large sieve inequalities for families of L-functions
Matt Young
4:00pm|Wolfensohn Hall and Remote Access

Large sieve inequalities are useful and flexible tools for understanding families of L-functions.  The quality of the bound is one measure of our understanding of the corresponding family.  For instance, they may directly give rise to good bounds...

Number theoretic aspects of multiplicative chaos
Adam Harper
9:00am|Wolfensohn Hall and Remote Access

Abstract: Multiplicative chaos is the general name for a family of probabilistic objects, which can be thought of as the random measures obtained by taking the exponential of correlated Gaussian random variables. Multiplicative chaos turns out to be...

Gaussian multiplicative chaos: applications and recent developments
Nina Holden
10:30am|Wolfensohn Hall and Remote Access

I will give an introduction to Gaussian multiplicative chaos and some of its applications, e.g. in Liouville theory. Connections to random matrix theory and number theory will also be briefly discussed.

A few results and conjectures on some product-ratio correlation functions of characteristic polynomials of beta-Hermite ensembles
Yan Fyodorov
12:00pm|Wolfensohn Hall and Remote Access

Rank-one non-Hermitian deformations of  tridiagonal beta-Hermite Ensembles have been introduced by R. Kozhan several years ago. For a fixed N and beta>0 the joint probability density of N complex eigenvalues  was shown to have a form of a...

The Fyodorov-Hiary-Keating Conjecture
Louis-Pierre Arguin
2:30pm|Wolfensohn Hall and Remote Access

In 2012, Fyodorov, Hiary & Keating and Fyodorov & Keating proposed a series of conjectures describing the statistics of large values of zeta in short intervals of the critical line. In particular, they relate these statistics to the ones of log...

Large deviation estimates for Selberg’s central limit theorem, applications, and numerics
Emma Bailey
4:00pm|Wolfensohn Hall and Remote Access

Selberg’s celebrated central limit theorem shows that the logarithm of the zeta function at a typical point on the critical line behaves like a complex, centered Gaussian random variable with variance $\log\log T$. This talk will present recent...

RMT statistics in number theory and in quantum chaos
9:00am|Wolfensohn Hall and Remote Access

Montgomery's pair correlation conjecture ushered a new paradigm into the theory of the Riemann zeta function, that of the occurrence of Random Matrix Theory statistics, as developed in part by Dyson, into the theory. A parallel development was the...

Half-Isolated Zeros and Zero-Density Estimates
Kyle Pratt
12:00pm|Wolfensohn Hall and Remote Access

We introduce a new zero-detecting method which is sensitive to the vertical distribution of zeros of the zeta function. This allows us to show that there are few ‘half-isolated’ zeros. If we assume that the zeros of the zeta function are restricted...

The recipe for moments of $L$-functions and characteristic polynomials of random matrices
Sieg Baluyot
2:30pm|Wolfensohn Hall and Remote Access

In 2005, Conrey, Farmer, Keating, Rubinstein, and Snaith formulated a 'recipe' that leads to precise conjectures for the asymptotic behavior of integral moments of various families of $L$-functions. They also proved exact formulas for moments of...

Sums of certain arithmetic functions over $\mathbb{F}_q[T]$ and non-unitary distributions
9:00am|Wolfensohn Hall and Remote Access

In 2018 Keating, Rodgers, Roditty-Gershon and Rudnick established relationships of the mean-square of sums of the divisor function $d_k(f)$ over short intervals and over arithmetic progressions for the function field $\mathbb{F}_q[T]$ to certain...

Moments of large families of Dirichlet L-functions
Vorrapan Chandee
10:30am|Wolfensohn Hall and Remote Access

Sixth and higher moments of L-functions are important and challenging problems in analytic number theory. In this talk, I will discuss my recent joint works with Xiannan Li, Kaisa Matom\"aki and Maksym Radziw\il\l on an asymptotic formula of the...

Equivariant localization and quot schemes
8:00pm|S-101

Equivariant localization provides a powerful method for explicitly computing equivariant and ordinary cohomology rings of spaces with large symmetry groups. One of the most useful localization formulas, due to Goresky-Kottwitz-MacPherson, describes...

D-Modules and Loop Spaces
2:00pm|S-101

Equivariant localization relates the geometry of a space to the geometry of the fixed points of a group action. A categorified application of this technique allows one to recover D-modules on a smooth space from coherent sheaves on its loop space...

Character Sheaves and Real Groups

Categorification of quantum groups and Floer theory
Hao Zheng
2:00pm|S-101

This talk is concerned with categorification of quantum Kac-Moody algebras and their integrable representations. First, I show how to fulfill the task by using sheaf theory. Then I will argue that the constructions could be well understood and...

Representations of Rational Cherednik Algebras and Miracles of Science

I will report on a work in progress joint with Andrei Okounkov. We extend the methods developed in an earlier work with Mirkovic and Rumynin on modular representations of semi-simple Lie algebras to representation of symplectic reflection algebras...
