Discrete torsion, orbifold elliptic genera, and the chiral de Rham complex
Anatoly Libgober, Matthew Szczesny
Given a compact complex algebraic variety with an effective action of a finite group , and a class , we introduce an orbifold elliptic genus with discrete tors…
Orbifold conformal blocks and the stack of pointed G-covers
Matthew Szczesny
Starting with a vertex algebra , a finite group of automorphisms of , and a suitable collection of twisted --modules, we construct (twisted) --modules on the stack…
Chiral de Rham Complex and Orbifolds
Edward Frenkel, Matthew Szczesny
Suppose that a finite group acts on a smooth complex variety . Then this action lifts to the Chiral de Rham Complex of and to its cohomology by automorphisms of the vert…
Twisted Modules over Vertex Algebras on Algebraic Curves
Edward Frenkel, Matthew Szczesny
We extend the geometric approach to vertex algebras developed by the first author to twisted modules, allowing us to treat orbifold models in conformal field theory. Let be a v…
Wakimoto Modules for Twisted Affine Lie Algebras
Matthew Szczesny
We construct Wakimoto modules for twisted affine Lie algebras, and interpret the construction in terms of vertex algebras and their twisted modules. Using the Wakimoto realization,…
