A note on the $m$ -extended module categories of Nakayama algebras

Endre SÃ¸rmo Rundsveen

We study the extended module category $m -mod I^$ of an algebra $I^$ , recently introduced by Gupta and Zhou. The existence of a postprojective component of $m\operator…

$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…

$I ¨ _{d}$ -tilting theory for linear Nakayama algebras

Endre S. Rundsveen, Laertis Vaso

Support $I ¨ $ -tilting pairs, functorially finite torsion classes and $2$ -term silting complexes are three much studied concepts in the representation theory of finite-dimensional al…

Universal Extensions and Ext-Orthogonal Complements of Torsion Classes

Endre S. Rundsveen

We show that torsion pairs in Krull--Schmidt abelian categories induce an equivalence between the subcategory of torsion-free objects admitting universal extensions to the torsion…
