Hochschild cohomology of smash products and rank one Hopf algebras

S. M. Burciu, S. J. Witherspoon

We give some general results on the ring structure of Hochschild cohomology of smash products of algebras with Hopf algebras. We compute this ring structure explicitly for a large…

Varieties for Modules of Quantum Elementary Abelian Groups

Julia Pevtsova, Sarah Witherspoon

We define a rank variety for a module of a noncocommutative Hopf algebra $A = Λ ⋊ G$ where $Λ = k [X_{1}, ..., X_{m}] / (X_{1}^{ℓ}, ..., X_{m}^{ℓ})$ , $G = ({\mathbb Z}/\ell{\mathbb…

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…
