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_…

On self-orthogonal modules in Iwanaga-Gorenstein rings

Rene Marczinzik

Let $A$ be an Iwanaga-Gorenstein ring. Enomoto conjectured that a self-orthogonal $A$ -module has finite projective dimension. We prove this conjecture for $A$ having the property t…
