| Research Abstract |
We studied wild harmonic bundles and algebraic holonomic D-modules. We established the correspondence between semisimple algebraic holonomic D-modules and polarizable wild pure twistor D-modules through wild harmonic bundles. As an application, we showed that semisimplicity of algebraic holonomic D-modules is preserved by push-forward. In the course of the study, we obtained fundamental theorems for algebraic meromorphic flat bundles, namely, a resolution of turning points, and a description of irregular singularity in terms of a system of Stokes filtrations.
