"Euler obstruction and indices of vector fields"

 

 

Northeastern University

1:30-2:30 p.m., Monday, June 22, 1998

 
 
Abstract:  The Euler obstruction is an invariant of singularities which has been introduced by R. MacPherson. Lê and Teissier have given a formula for this invariant, in terms of the multiplicities of Polar Varieties. We shall give another formula obtained by a direct geometrical calculation which involves indices of vector fields on singular spaces.
