Log higher Albanese maps and examples where special values of zeta function appear

Summary: We construct fine moduli of log mixed Hodge structures with group action. We apply this to partial compactifications of higher Albanese manifolds. As an example, we describe in our framework a result of Deligne in which polylog functions and special values of zeta function appear on boundary points. This talk is based on a joint work with Kazuya Kato and Chikara Nakayama.
