Geometric polarized log Hodge structures for semistable families
Taro Fujisawa, Chikara Nakayama
We prove that a projective semistable morphism of fs log analytic spaces yields polarized log Hodge structures in the canonical way.

Classifying spaces of degenerating mixed Hodge structures, VI: Log real analytic functions and log functions
Kazuya Kato, Chikara Nakayama, Sampei Usui
To advance our log Hodge theory, we introduce log real analytic functions and log functions, define how to integrate them, and prove the log Poincaré lemma. We give be…
