Traces of reciprocal singular moduli

Number Theory 2020-06-19 v2

Abstract

We show that the generating series of traces of reciprocal singular moduli is a mixed mock modular form of weight 3/23/2 whose shadow is given by a linear combination of products of unary and binary theta functions. To prove these results, we extend the Kudla-Millson theta lift of Bruinier and Funke to meromorphic modular functions.
