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

Endre Sørmo Rundsveen

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

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…

$τ_{d}$ -tilting theory for linear Nakayama algebras

Endre S. Rundsveen, Laertis Vaso

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

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

Erlend D. Børve, Jacob Fjeld Grevstad, Endre S. Rundsveen

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