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

iCal  iCal

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).
