Skew Group Algebras, (Fg) and Self-injective Rad-Cube-Zero Algebras
Mads Hustad Sandøy
We classify self-injective radical cube zero algebras with respect to whether they satisfy certain finite generation conditions sufficient to have a fruitful theory of support vari…

On compatibility of Koszul- and higher preprojective gradings
Darius Dramburg, Mads Hustad Sandøy
We investigate compatibility of gradings for an almost Koszul or Koszul algebra that is also the higher preprojective algebra of an -hereditary algebra . For…

Higher homological algebra for one-point extensions of bipartite hereditary algebras and spectral graph theory
Karin M. Jacobsen, Mads Hustad Sandøy, Laertis Vaso
In this article we study higher homological properties of -levelled algebras and connect them to properties of the underlying graphs. Notably, to each -representation-finite…
