The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on January 10, 2017 at 14:00 in Room 478 of IMI.

A talk on:

Excess Intersection and Differential Equisingularity

will be delivered by Antoni Rangachev.

Everybody is invited.

Abstract. We prove an excess intersection formula that determines the change of the top self-intersection numbers of families of Cartier divisors. We apply the formula to settle a long-standing problem of providing numerical control for Whitney (differential) equisingularity for families of arbitrary isolated singularities.
