Irreducible finite dimensional representations of W-algebras

Date: 
Wednesday 25th March 2009 - 09:00 to 10:00
Venue: 
INI Seminar Room 1
Abstract: 
W-algebras (of finite type) are certain associative algebras constructed from nilpotent orbits in semisimple Lie algebras. In this talk I am going to describe a relation between irreducible finite dimensional representations of a W-algebra and primitive ideals of the universal enveloping algebra whose associated variety coincides with the closure of the given orbit.
