Generic sections of essentially isolated determinantal singularities

Algebraic Geometry 2015-04-27 v1

Abstract

We study the essentially isolated determinantal singularities (EIDS), defined by W. Ebeling and S. Gusein-Zade, as a generalization of isolated singularity. We prove in dimension 33 a minimality theorem for the Milnor number of a generic hyperplane section of an EIDS, generalizing previous results by J. Snoussi in dimension 22. We define strongly generic hyperplane sections of an EIDS and show that they are still EIDS. Using strongly general hyperplanes, we extend a result of L\^e D. T. concerning constancy of the Milnor number.
