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