Some homological properties of skew PBW extensions arising in non-commutative algebraic geometry
Oswaldo Lezama, Helbert Venegas
In this short paper we study for the skew PBW (Poincaré-Birkhoff-Witt) extensions some homological properties arising in non-commutative algebraic geometry, namely, Auslander-Goren…

Non-commutative algebraic geometry of semi-graded rings
Oswaldo Lezama, Edward Latorre
In this paper we introduce the semi-graded rings, which extend graded rings and skew PBW extensions. For this new type of non-commutative rings we will discuss some basic problems…
