Outline of Final Research Achievements

The motivation of this research was to understand the Hodge realization of mixed Tate motives. We constructed ceratain complex of topological chains which we call admissible chains. Via this complex we constructed a Hodge realization functor of mixed Tate motives, and a description of the Abel-Jacobi map of higher Chow cycles.

Academic Significance and Societal Importance of the Research Achievements

これまで構成されたモチーフの圏の実現関手は、ある意味で明快だが高度に抽象的であった。具体的な構成を与えたことで、より周期積分との関係が明らかになった。
