Skew group algebras, invariants and Weyl Algebras
Roberto Martinez-Villa, Jeronimo Mondragon
The aim of this paper is two fold: First to study finite groups of automorphisms of the homogenized Weyl algebra , the skew group algebra , the ring of inva…
Dualities in Koszul graded AS Gorenstein algebras
Roberto Martinez-Villa
The paper is dedicated to the study of certain non commutative graded AS Gorenstein algebras . The main result of the paper is that for Koszul algebras with Yoneda algebra $…
Local Cohomology and non commutative Gorenstein algebras
Roberto Martinez-Villa
In this paper we continue the study of non connected graded Gorenstein algebras initiated in a previous paper, the main result is the proof of a version of the Local Cohomology for…
On the homogenized Weyl Algebra
Roberto Martinez-Villa, Jeronimo Mondragon
The aim of this paper is to give relations between the category of finetely generated graded modules over the homogeneized Weyl algebra , the finetely generated modules over…
Koszul Algebras and Sheaves over Projective Space
Roberto Martinez-Villa
We are going to show that the sheafication of graded Koszul modules over form an important subcategory of the coher…
Hochschild Cohomology of skew group rings and invariants
Eduardo do Nascimento Marcos, Roberto Martinez-Villa, Maria Izabel Ramalho Martins
Let be a -algebra and be a group acting on . We show that also acts on the Hochschild cohomology algebra and that there is a monomorphism of rin…
