Local theta correspondence and Galois periods

Representation Theory 2026-03-10 v1 Number Theory

Abstract

We study the behavior of Galois periods under the local theta correspondence for even orthogonal and symplectic groups. Specifically, we compare their multiplicities and construct explicit transfer maps. Furthermore, we establish both an adjoint relation and a relative character relation for these periods.
