Equivariant $H F_{p}$ -modules are wild

Jacob Fjeld Grevstad, Clover May

Let $k$ be an arbitrary field of characteristic $p$ and let $G$ be a finite group. We investigate the representation type, derived representation type, and singularity category of…

$I ¨ $ -tilting finiteness and $g$ -tameness: Incidence algebras of posets and concealed algebras

Erlend D. BÃ¸rve, Jacob Fjeld Grevstad, Endre S. Rundsveen

We prove that any $I ¨ $ -tilting finite incidence algebra of a finite poset is representation-finite, and that any $g$ -tame incidence algebra of a finite simply connected po…
