A Shimura-Shintani correspondence for rigid analytic cocycles of higher weight

Abstract

This paper takes the first steps towards a systematic study of additive rigid meromorphic cocycles of higher weight. These were introduced by Darmon and Vonk, who focused on multiplicative and weight two cocycles. After classifying certain rigid meromorphic cocycles of weight 2k2k, we construct an explicit holomorphic kernel function realising a Shimura-Shintani style correspondence from modular forms of weight k+1/2k+1/2 and level 4p24p^2 to rigid analytic cocycles of weight 2k2k on SL2(Z[1/p])_2(\mathbb{Z}[1/p]).
