The Auslander-Gorenstein condition for monomial algebras

Viktória Klász

This paper investigates the Auslander-Gorenstein property for monomial algebras. First, we prove that every Auslander-Gorenstein monomial algebra is a string algebra and present a…

Nakayama algebras of small homological dimension and pattern avoiding permutations

Viktória Klász, René Marczinzik, Judith Marquardt

We give a combinatorial classification of Nakayama algebras of small homological dimension using the Krattenthaler bijection between Dyck paths and 132-avoiding permutations.

Selfextensions of modules over group algebras

Bernhard Böhmler, Karin Erdmann, Viktória Klász +1

Let $K G$ be a group algebra with $G$ a finite group and $K$ a field and $M$ an indecomposable $K G$ -module. We pose the question, whether $E x t_{K G}^{1} (M, M) \neq = 0$ implies that $Ext_…
