Title: Orbifold String Topology

Speaker: Ernesto Lupercio

Institution: Mathematics Department, CINVESTAV, México DF., México

Abstract

In this talk I will present a version of String Topology that generalizes the Chas-Sullivan theory of a smooth manifold to an orbifold. This theory also generalizes the Dijkgraaf-Witten toy model for a finite group, and shares many characteristics with the Chen-Ruan theory of an orbifold. This is joint work with B. Uribe and M. Xicotencatl.
