Title: Intersections of HeegnerDrinfeld cycles
Abstract: I'll present a formula which relates the intersection of two HeegnerDrinfeld cycles in the moduli stack of shtukas to derivatives of certain toric period integrals. The formula is a "higher order" generalization of the GrossKohnenZagier formula, in the function field setting, and is inspired by recent work of Yun and W. Zhang. Our formula gives strong evidence that HeegnerDrinfeld cycles coming from different quadratic fields are collinear in cohomology. This is joint work with Ben Howard.
