Inertia Orbifolds, Configuration Spaces and the Ghost Loop Space
Ernesto Lupercio, Bernardo Uribe
In this paper we define and study the "ghost loop orbifold" of an orbifold consisting of those loops that remain constant in the coarse moduli space of . We construct a conf…
Loop Groupoids, Gerbes, and Twisted Sectors on Orbifolds
Ernesto Lupercio, Bernardo Uribe
The purpose of this paper is to introduce the notion of loop groupoid associated to a groupoid. After studying the general properties of the loop groupoid, we show how this notion…
Orbifold Cohomology of the Symmetric Product
Bernardo Uribe
Chen and Ruan's orbifold cohomology of the symmetric product of a complex manifold is calculated. An isomorphism of rings (up to a change of signs) $H_{orb}^*(X^n/S_n;\complex) \co…
Gerbes over Orbifolds and Twisted K-theory
Ernesto Lupercio, Bernardo Uribe
In this paper we construct an explicit geometric model for the group of gerbes over an orbifold . We show how from its curvature we can obtain its characteristic class in $H^3(X…
