Period integrals and Hodge modules
arXiv:1910.00035
Abstract
We define a map attached to any polarized Hodge module such that the restriction of to a locus on which is a variation of Hodge structures induces the usual period integral pairing for this variation of Hodge structures. In the case that is the minimal extension of a simple polarized variation of Hodge structures , we show that the homotopy image of is the minimal extension of the graph morphism of the usual period integral map for .
