Research Abstract

By applying the theory of mixed Hodge modules, many new results are obtained in various fields of algebraic geometry such as Hodge structures, algebraic cycles, singularities, characteristic classes, etc. In case of characteristic classes, for instance, a completely new formula for the Hirzebruch-Milnor classes of complete intersections of smooth projective varieties is obtained by using vanishing cycles of mixed Hodge modules inductively. Many of these results cannot be proved without using the theory of mixed Hodge modules.
