Poles of p-adic Asai L-functions and distinguished representations

Number Theory 2026-01-08 v2 Representation Theory

Abstract

We give a criterion in terms of p-adic Asai L-functions for a cuspidal automorphic representation of GL(2) over a real quadratic field to be a distinguished representation, providing a p-adic counterpart of a well-known theorem of Flicker for the complex Asai L-function.
