Finite groups acting linearly: Hochschild cohomology and the cup product
Anne V. Shepler, Sarah Witherspoon
When a finite group acts linearly on a complex vector space, the natural semi-direct product of the group and the polynomial ring over the space forms a skew group algebra. This al…

Quantum differentiation and chain maps of bimodule complexes
Anne V. Shepler, Sarah Witherspoon
We consider a finite group acting on a vector space and the corresponding skew group algebra generated by the group and the symmetric algebra of the space. This skew group algebra…

Hochschild Cohomology and Graded Hecke Algebras
Anne V. Shepler, Sarah Witherspoon
We develop and collect techniques for determining Hochschild cohomology of skew group algebras S(V)#G and apply our results to graded Hecke algebras. We discuss the explicit comput…
