Products in Hochschild cohomology and Grothendieck rings of group crossed products

Sarah J. Witherspoon

We give a general construction of rings graded by the conjugacy classes of a finite group. Some examples of our construction are the Hochschild cohomology ring of a finite group al…

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…
