SUAREZ, Héctor  and  REYES, Armando. Nakayama Automorphism of Some Skew PBW Extensions. ing.cienc. [online]. 2019, vol.15, n.29, pp.157-177. ISSN 1794-9165.  https://doi.org/10.17230/ingciencia.15.29.6.

Let R be an Artin-Schelter regular algebra and A = σ(R)(x1…,x n ) be a graded quasi-commutative skew PBW extension over R. In this paper we describe the Nakayama automorphism of A using the Nakayama automorphism of the ring of coefficients R. We calculate explicitly the Nakayama automorphism of some skew PBW extensions.

Keywords : Skew PBW extensions; Nakayama automorphism; Artin-Schelter regular algebras; Calabi-Yau algebras.
