Let\varLambda Λ be a right-peak algebra in the sense of Simson (J Algebra 92: 532–571,
1985). Denote by mod _ sp (\varLambda) mod sp (Λ) the full subcategory of mod …

Let R= k (Q, I) be a finite-dimensional algebra over a field k determined by a bound quiver
(Q, I). We show that if R is a simply connected right multipeak algebra which is chord-free …

Let k be a comniutative field. A finite dimensional k-algebra R is called a rtght peak algebra if
there exists a simple projective right ideal P,= e, R (called a right peak of R) such that the …

The main aim of this paper is to give a simple criterion for a finite poset I with two maximal
elements to have the category I-spr of socle projective representations of tame …

We explore some properties of wide subcategories of the category mod (Λ) of finitely
generated left Λ-modules, for some artin algebra Λ. In particular we look at wide finitely …

Right peak rings and their socle projective modules were introduced and studied by the
second author [49, 50, 471 in a connection with a study of subspace categories of vector …

Let A; be a field and R a finite dimensional/c-algebra. We call R a right peak ring if soc R the
socle of R as a right i?-module is projective. A right peak ring is introduced by Simson in [7] …

Let $ A,\; B $ be artinian rings and let $ _A {M_B} $ be an $(AB) $-bimodule which is a
finitely generated left $ A $-module and a finitely generated right $ B $-module. A right $ _A …

Let R be a right peak artinian ring (1.1). We prove that under suitable assumptions (3.7) on R
there exists a preprojective component of the Auslander-Reiten valued quiver Гнр (Я) of the …

Let \mitΛ be a connected artin algebra with the postprojective partition \calP_0,⋯,\calP_n,⋯,\
calP\!_∞, and assume that \calP_0∪\calP_1 is closed under indecomposable submodules …
