A Gross-Kohnen-Zagier type formula for moduli of shtukas with Iwahori level structures
arXiv:1904.11479
Abstract
In this paper I'm going to study the intersection of two Heegner-Drinfeld cycles coming from two different nonsplit tori on the Yun-Zhang moduli stack of Drinfeld stukas with Iwahori level structure. We will see that the intersection number is related to a certain period integral. It is an extension of the result by Howard-Shinidman to the Iwahori case.
