A duality theorem for generalized Koszul algebras

Roberto Martinez Villa, Manuel Saorin

We show that if $Λ$ is a $n$ -Koszul algebra and $E = E (Λ)$ is its Yoneda algebra, then there is a full subcategory $L_{E}$ of the category $G r_{E}$ of graded $E$ -modules, which…

Killing of supports on graded algebras

R. Martinez Villa, M. Saorin

Killing of supports along subsets $U$ of a group $G$ and regradings along certain maps of groups $ϕ : G^{'} ⟶ G$ are studied, in the context of group-graded algeb…
