Classifying spaces of degenerating mixed Hodge structures, II: Spaces of SL(2)-orbits

Algebraic Geometry 2015-01-14 v1

Abstract

We construct an enlargement of the classifying space of mixed Hodge structures with polarized graded quotients, by adding mixed Hodge theoretic version of SL(2)-orbits. This space has a real analytic structure and a log structure with sign. The SL(2)-orbit theorem in several variables for mixed Hodge structures can be understood naturally with this space.
