## Number Theory Seminar

**Time: ** 09:45AM - 10:45AM

**Location: ** BLOC 302

**Speaker: **Shifan Zhao, The Ohio State University

**Title: ***Low-lying zeros of L-functions attached to Siegel modular forms*

**Abstract: **The Katz-Sarnak heuristic predicts that the distribution of low-lying zeros of families of automorphic L-functions are governed by certain classical compact groups determined by the family. In this talk I will present some recent progress concerning low-lying zeros of spinor and standard L-functions of Siegel modular forms. I will first describe these results in the $k$ (weight) aspect, and then explain how to extend the support of Fourier transforms of test functions by averaging over $k$. I will also discuss applications towards the non-vanishing of central L-values.

## On the stochastic Camassa—Holm equation with transport noise

**Time: ** 4:00PM - 5:00PM

**Location: ** BLOC 117

**Speaker: **Helge Holden, Norwegian University of Science and Technology

**Description: **We will discuss recent work regarding the stochastic
Camassa—Holm equation. In particular, we will show existence
of a weak, global, dissipative solution of the Cauchy initial-value
problem on the torus.
This is joint work with L. Galimberti (King’s College), KH Karlsen (Oslo), and
PHC Pang (NTNU/Oslo).
