Title: | D-module structure of local cohomology modules |

Seminar: | Algebra and Number Theory Seminar |

Speaker: | Jen-Chieh Hsiao, Purdue University |

Abstract: |

Let R be a polynomial ring and I be an ideal of R. It is well known that the local cohomology modules of R supported at I have finite length as D-modules. They are in fact holonomic D-modules. In this talk, I will define these terms and will try to illustrate this classical result by a simple example and explain how to generalize it to the case where R is a toric algebra and I is a monomial ideal of R. Some computations of characteristic varieties of local cohomology modules will also be discussed. |
