Theta block conjecture for paramodular forms of weight 2

Number Theory 2019-10-03 v2

Abstract

In this paper we construct an infinite family of paramodular forms of weight 22 which are simultaneously Borcherds products and additive Jacobi lifts. This proves an important part of the theta-block conjecture of Gritsenko--Poor--Yuen (2013) related to the only known infinite series of theta-blocks of weight 22 and qq-order 11. We also consider some applications of this result.
