Drinfeld Orbifold Algebras
Anne V. Shepler, Sarah J. Witherspoon
We define Drinfeld orbifold algebras as filtered algebras deforming the skew group algebra (semi-direct product) arising from the action of a finite group on a polynomial ring. The…

Hochschild cohomology and quantum Drinfeld Hecke algebras
Deepak Naidu, Sarah Witherspoon
Quantum Drinfeld Hecke algebras are generalizations of Drinfeld Hecke algebras in which polynomial rings are replaced by quantum polynomial rings. We identify these algebras as def…

Support Varieties and Representation Type of Self-Injective Algebras
Joerg Feldvoss, Sarah Witherspoon
We use the theory of varieties for modules arising from Hochschild cohomology to give an alternative version of the wildness criterion of Bergh and Solberg: If a finite dimensional…
