| Outline of Final Research Achievements |
We studied a better definition of mixed Hodge modules, and got many new results in various fields of algebraic geometry such as algebraic cycles, singularities, Hodge structures, characteristic classes, and so on by applying the theory of mixed Hodge modules. For instance, the roots of the b-functions of certain homogeneous polynomials can be determined by calculating the Hilbert series of the quotient ring of the polynomial ring divided by the Jacobian ideal generated by the partial derivatives of the given polynomial. This is totally impossible without using the theory of mixed Hodge modules.
