Abstract

The study of characteristic classes of singular varieties is a current theme and has been widely used in several areas of science. The aim of this project is to study the Schwartz-MacPherson classes and their unfolding. One of the approaches of the project is the construction of equivariant classes following the notion introduced by Ohmoto for the case of Schwartz-MacPherson classes. We present equivariant characteristic classes of Milnor type and Fulton type for singular hypersurfaces. (AU)
