Some remarks on strong multiplicity one for paramodular forms

Number Theory 2026-04-29 v2

Abstract

We establish several refined strong multiplicity one results for paramodular cusp forms by using automorphic and Galois-theoretic methods. We also give an application to distinguishing eigenforms by the twisted central values of the spinor LL-functions, which is based on a result in Radziwi{\l}{\l} and Yang 2023 (arXiv:2304.09171).
