Limits of Hodge structures in several variables, II

Abstract

The aim of this article is to study degeneration of the variations of Hodge structure associated to a proper Kähler semistable morphism. We prove that the weight filtrations constructed in the author's previous paper coincide with the monodromy weight filtrations on the relative log de Rham cohomology groups of a proper Kähler semistable morphism. Moreover, we show that the limiting mixed Hodge structures form admissible variations of mixed Hodge structure.

Since Lemma 2.5 in the previous version was false, several corrections have been made. The main results are the same as in the previous version. Moreover, the presentation are improved
