We prove the following theorem: Let F be a nonarchimedean local field of characteristic zero and K a quadratic extension of F. Let S be the set of characters of K\* trivial on F \*. Let / 1 and / 2 be two characters of K\* such that / 1 | F \* =/ 2 | F \* {1. Let be a nontrivial additive character o

โฆ Synopsis
We prove that a Dirichlet series with a functional equation and Euler product of a particular form can only arise from a holomorphic cusp form on the Hecke congruence group ฮ 0 (13). The proof does not assume a functional equation for the twists of the Dirichlet series. The main new ingredient is a generalization of the familiar Weil's lemma that played a prominent role in previous converse theorems.

Let f (q { , q z )= n, r c(n, r) q n { q r z be a power series whose coefficients satisfy a particular periodicity condition depending on the integer r modulo 2m. We first associate to f (q { , q z ) a 2m-vector-valued function 4( f, s) via a generalized Mellin transform. Then we show that the funct
