Skew Derivations and Deformations of a Family of Group Crossed Products
Sarah J. Witherspoon
We obtain deformations of a crossed product of a polynomial algebra with a group, under some conditions, from universal deformation formulas. We show that the resulting deformation…

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…

Clifford correspondence for algebras
Sarah J. Witherspoon
We give a Clifford correspondence for an algebra A over an algebraically closed field, that is an algorithm for constructing some finite-dimensional simple A-modules from simple mo…
