A Localization Principle for Orbifold Theories
Tommaso de Fernex, Ernesto Lupercio, Thomas Nevins +1
In this article, written primarily for physicists and geometers, we survey several manifestations of a general localization principle for orbifold theories such as -theory, inde…
Stringy Chern classes of singular varieties
Tommaso de Fernex, Ernesto Lupercio, Thomas Nevins +1
Motivic integration and MacPherson's transformation are combined in this paper to construct a theory of "stringy" Chern classes for singular varieties. These classes enjoy strong b…
An Introduction to Gerbes on Orbifolds
Ernesto Lupercio, Bernado Uribe
This paper is a gentle introduction to some recent results involving the theory of gerbes over orbifolds for topologists, geometers and physicists. We introduce gerbes on manifolds…
Differential Characters on Orbifolds and String Connections I
Ernesto Lupercio, Bernardo Uribe
In this paper we introduce the Cheeger-Simons cohomology of a global quotient orbifold. We prove that the Cheeger-Simons cohomology of the orbifold is isomorphic to its Beilinson-D…
The global McKay-Ruan correspondence via motivic integration
E. Lupercio, M. Poddar
The purpose of this paper is to show how the motivic integration methods of Kontsevich, Denef-Loeser and Looijenga can be adapted to prove the McKay-Ruan correspondence, a generali…
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…
