The Ranking-Selberg integral on ${\bf GSp(2)}$ for square free levels

Number Theory 2026-04-29 v2

Abstract

We explicitly compute the Rankin-Selberg type integral introduced by Piatetski-Shapiro over adeles for vector-valued Siegel cusp forms of square-free levels Γ0(N)\Gamma_0(N). On the way, for particular test functions in the Bessel models of irreducible admissible representations, exact evaluations of the local zeta-integrals are given.
