A Converse Theorem for Metaplectic Eisenstein Series on $S{L}_2(\mathbb{A})$

Abstract

The purpose of this work is to produce a converse theorem for adelic Eisenstein series on the double metaplectic cover of the group $S{L}_2(\mathbb{A})$. We show that the double Dirichlet series, which satisfy the natural functional equations required in our theorem, are in fact Mellin transforms at infinity of metaplectic Eisenstein series.
