Seminar for Unitary Representations and Automorphic Forms

On Monday, May 16, 2022, 10:00 hours, Lei Zhang (Department of Mathematics, National University of Singapore) will hold lecture as part of Seminar for Unitary Representations and Automorphic Forms titled:

“Multiplicities for strongly tempered spherical varieties”.

Abstract: In this talk, we will discuss the local multiplicity formula of strongly tempered spherical subgroups, which have similar properties like Gan-Gross-Prasad conjecture. In particular, we formulate the epsilon dichotomy conjecture for those spherical subgroups and prove this conjecture for the tempered representations of endoscopy type. Globally, the corresponding automorphic periods are related to the central values of certain L-functions. This is a joint project with Chen Wan at Rutgers University—Newark.
