Abstract
Yun introduced a zeta function whose special values give the orbital integrals for GL_n. Arthur later proposed to use Yun's zeta function to extend the work of Ali Altug on beyond endoscopy for GL_2. In this talk, I will discuss how Yun's zeta function can be applied to give isolation for the trivial representation, which is the first step in the beyond endoscopy program.
Speaker Intro
Dr. DENG Taiwang has joined BIMSA in November 2022 as an Assistant Professor. His research interests are in the Langlands program (broadly speaking, the arithmetic, analytic and representation aspects of it). He obtained a Phd in Mathematics from the University of Paris 13. Previously, he has held the postdoctorial positions in Bonn University, the Max Planck Institute of Mathematics in Bonn and Tsinghua University.
