Algebraic deformations arising from orbifolds with discrete torsion
Andrei Caldararu, Anthony Giaquinto, Sarah Witherspoon
We develop methods for computing Hochschild cohomology groups and deformations of crossed product rings. We use these methods to find deformations of a ring associated to a particu…

Non-Fine Moduli Spaces of Sheaves on K3 Surfaces
Andrei Caldararu
In general, if M is a moduli space of stable sheaves on X, there is a unique alpha in the Brauer group of M such that a pi_M^* alpha^{-1}-twisted universal sheaf exists on X times…

Derived Categories of Twisted Sheaves on Elliptic Threefolds
Andrei Caldararu
We construct an equivalence between the derived category of sheaves on an elliptic threefold without a section and a derived category of twisted sheaves (modules over an Azumaya al…
