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…

Quantum Drinfeld Hecke Algebras
Viktor Levandovskyy, Anne V. Shepler
We consider finite groups acting on quantum (or skew) polynomial rings. Deformations of the semidirect product of the quantum polynomial ring with the acting group extend symplecti…
