Resolutions over Koszul algebras

E. L. Green, G. Hartman, E. N. Marcos +1

In this paper we show that if $Λ = ⨿_{i \geq 0} Λ_{i}$ is a Koszul algebra with $Λ_{0}$ isomorphic to a product of copies of a field, then the minimal projective resolution of $Λ_{0}$ a…

Hochschild Cohomology of skew group rings and invariants

Eduardo do Nascimento Marcos, Roberto Martinez-Villa, Maria Izabel Ramalho Martins

Let $A$ be a $k$ -algebra and $G$ be a group acting on $A$ . We show that $G$ also acts on the Hochschild cohomology algebra $H H^{∙} (A)$ and that there is a monomorphism of rin…

Skew category, Galois covering and smash product of a $k$ -category

Claude Cibils, Eduardo N. Marcos

In this paper we consider categories over a commutative ring provided either with a free action or with a grading of a not necessarily finite group. We define the smash product cat…
