Nakayama automorphisms of Ore extensions over polynomial algebras
Liyu Liu, Wen Ma
Nakayama automorphisms play an important role in several mathematical branches, which are known to be tough to compute in general. We compute the Nakayama automorphism of any O…

On homological smoothness of generalized Weyl algebras over polynomial algebras in two variables
Liyu Liu
Homological smoothness and twisted Calabi-Yau property of generalized Weyl algebras over polynomial algebras in two variables is studied. A necessary and sufficient condition to be…
