Enveloping Algebra and Skew Calabi-Yau algebras over Skew Poincaré-Birkhoff-Witt Extensions
Armando Reyes, Héctor Suárez
In this paper we show that the tensor product of skew PBW extensions is a skew PBW ex- tension. We also characterize the enveloping algebra of a skew PBW extension. Finally, we est…

A generalized Koszul property for skew PBW extensions
Héctor Suárez, Armando Reyes
Let R be a commutative algebra. In this paper we show that constant skew PBW extensions of a generalized Koszul algebra R are also generalized Koszul. Let A be a semi-commutative s…
