Title: Generalizations of the global Euler obstruction and critical points

Abstract: Seade, Tibar and Verjovsky (Math. Annalen, 2005) defined the
global Euler obstruction of an affine complex algebraic set and they
gave a polar multiplicity formula for this obstruction.
In this talk, we define several generalizations of the global Euler
obstruction and give several generalizations of the polar multiplicity
formula. This is a joint work with Nivaldo Grulha.
