Abstract
Suppose that is an Ore extension with an automorphism. It is proved that if is twisted Calabi-Yau of dimension , then is twisted Calabi-Yau of dimension . The relation between their Nakayama automorphisms is also studied. As an application, the Nakayama automorphisms of a class of 5-dimensional Artin-Schelter regular algebras are given explicitly.
