Orbifold conformal blocks and the stack of pointed G-covers

Algebraic Geometry 2007-05-23 v2 Quantum Algebra

Abstract

Starting with a vertex algebra VV, a finite group GG of automorphisms of VV, and a suitable collection of twisted VV--modules, we construct (twisted) DD--modules on the stack of pointed GG--covers, introduced by Jarvis, Kaufmann, and Kimura. The fibers of these sheaves are spaces of orbifold conformal blocks defined in joint work with Edward Frenkel. The key ingredient is a GG--equivariant version of the Virasoro uniformization theorem.
