Algebraic Geometry Seminar

Title: Local volumes, equisingularity, and generalized smoothability
Speaker: Antoni Rangachev
Speaker Info: Univ. of Chicago
Brief Description:
Special Note:

In this talk I will introduce a class of singularities that generalizes the class of smoothable singularities: these are all singularities that admit deformations to Deficient Conormal Singularities (DCS). I will discuss how this new class arises from problems in differential equisingularity and how it relates to the local volume of a line bundle. Using Thom's transversality I will show that under a certain hypothesis codimension 2, codimension 3, almost complete intersections, and determinantal singularities admit deformations to DCS.
