The Jacobian, reflection arrangement and discriminant for reflection Hopf algebras
arXiv:1902.00421
Abstract
We study finite dimensional semisimple Hopf algebra actions on noetherian connected graded Artin-Schelter regular algebras, and introduce definitions of the Jacobian, the reflection arrangement and the discriminant in a noncommutative setting.
