Pseudoconvexity at infinity in Hodge theory: a codimension one example

Algebraic Geometry 2023-02-10 v1

Abstract

The generalization of the Satake--Baily--Borel compactification to arbitrary period maps has been reduced to a certain extension problem on certain "neighborhoods at infinity". Extension problems of this type require that the neighborhood be pseudoconvex. The purpose of this note is to establish the desired pseudoconvexity in one relatively simple, but non-trivial, example: codimension one degenerations of a period map of weight two Hodge structures with first Hodge number h2,0h^{2,0} equal to 2.
