We study here when there are irreducible morphisms h: X→ Y and h′: Y→ Z between
indecomposable modules such that the composite h′ h is a non-zero morphism in R3 (X …

We prove that if A is an artin algebra, G is a finite group acting on A such that| G| is invertible
in A, and R= A [G] b is a basic algebra associated with the skew group algebra, then A is left …

Let A be an artin algebra. We are interested in studying the representation theory of A, thus
the category mod A of finitely generated right A-modules. For this purpose, we fix a full …

Let R be the pullback of two surjective homomorphisms of algebras A→ B and C→ B. Here
we consider a particular class, the so-called linearly oriented pullback, where the injective …

In this paper, we introduce and study a class of algebras which we call ada algebras. An
artin algebra is ada if every indecomposable projective and every indecomposable injective …

In this paper, we study the covering theory of laura algebras. We prove that if a connected
laura algebra is standard (that is, has a standard connecting component), then it has Galois …

Let Γ be a connected component of the Auslander–Reiten quiver Γ (modA) of an Artin
algebra. We show that Γ is quasi-directed if and only if the paths in indA, having end-points …

We give several equivalent characterisations of left (and hence, by duality, also of right)
supported algebras. These characterisations are in terms of properties of the left and the …
