On P-extending modules.
On artin algebras with almost all indecomposable modules of projective or injective dimension at most one
Andrzej Skowroński (2003)
Open Mathematics
Similarity:
Let A be an artin algebra over a commutative artin ring R and ind A the category of indecomposable finitely generated right A-modules. Denote to be the full subcategory of ind A formed by the modules X whose all predecessors in ind A have projective dimension at most one, and by the full subcategory of ind A formed by the modules X whose all successors in ind A have injective dimension at most one. Recently, two classes of artin algebras A with co-finite in ind A, quasi-tilted...

A duality result for almost split sequences
Lidia Hügel, Helmut Valenta (1999)
Colloquium Mathematicae
Similarity:
Over an artinian hereditary ring R, we discuss how the existence of almost split sequences starting at the indecomposable non-injective preprojective right R-modules is related to the existence of almost split sequences ending at the indecomposable non-projective preinjective left R-modules. This answers a question raised by Simson in [27] in connection with pure semisimple rings.
A characterization of representation-finite algebras
Andrzej Skowroński, M. Wenderlich (1991)
Fundamenta Mathematicae
Similarity:
Let A be a finite-dimensional, basic, connected algebra over an algebraically closed field. Denote by Γ(A) the Auslander-Reiten quiver of A. We show that A is representation-finite if and only if Γ(A) has at most finitely many vertices lying on oriented cycles and finitely many orbits with respect to the action of the Auslander-Reiten translation.
A note on tilting sequences

Open Mathematics
Similarity:
We discuss the existence of tilting modules which are direct limits of finitely generated tilting modules over tilted algebras.

On large selforthogonal modules

Similarity:
We construct non faithful direct summands of tilting (resp. cotilting) modules large enough to inherit a functorial tilting (resp. cotilting) behaviour.
