Abstract

Period spaces contain Hodge cycles, whose cohomology classes form the coefficients of certain modular forms, by work of Kudla and Millson. I will explain how this phenomenon survives when we pass to a toroidal compactification in the case of K3 type Hodge structures, and then give some geometric applications. This work is joint with Phil Engel and Salim Tayou.
