Rings and Algebras 2016-10-07 v1

Abstract

Let HH and LL be two Hopf algebras such that their comodule categories are monoidal equivalent. We prove that if HH is a twisted Calabi-Yau (CY) Hopf algebra, then LL is a twisted CY algebra when it is homologically smooth. Especially, if HH is a Noetherian twisted CY Hopf algebra and LL has finite global dimension, then LL is a twisted CY algebra.
