The Jacobian, reflection arrangement and discriminant for reflection Hopf algebras
Published 1 Feb 2019 in math.RA | (1902.00421v2)
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.
