Structure of irreducible homomorphisms to/from free modules

S Nasseh, R Takahashi - Algebras and Representation Theory, 2018 - Springer
The primary goal of this paper is to investigate the structure of irreducible monomorphisms to
and irreducible epimorphisms from finitely generated free modules over a noetherian local …

Relatively free modules on ring extensions

S Guo, X Wang, Z Yi - Communications in Algebra, 2021 - Taylor & Francis
A ring extension is a ring homomorphism preserving identities. In this paper, we give the
definition of relatively free modules on ring extensions and develop some basic properties of …

The endomorphism ring of a locally free module

WN Franzsen, P Schultz - Journal of the Australian Mathematical …, 1983 - cambridge.org
We identify a large class of rings over which locally free modules are determined by their
endomorphism rings. We characterize these endomorphism rings and consider under what …

Almost finite modules

D Apassov - Communications in Algebra, 1999 - Taylor & Francis
Assume that ϕ (R, m, k)→(S, n, l) is a local homomorphism between commutative noetherian
local rings R and S. We say that an S-module M is almost finite over R if it is finitely …

Isomorphisms between endomorphism rings of modules

KG Wolfson - Proceedings of the American Mathematical Society, 1995 - ams.org
We derive a necessary and sufficient condition that an isomorphism between the
endomorphism rings of modules be induced by a semi-linear isomorphism of the modules …

Homomorphisms with semilocal endomorphism rings between modules

F Campanini, SF El-Deken, A Facchini - Algebras and Representation …, 2020 - Springer
We study the category Morph (Mod-R) whose objects are all morphisms between two right R-
modules. The behavior of the objects of Mod-R whose endomorphism ring in Morph (Mod-R) …

Representation type of commutative Noetherian rings I: Local wildness

L Klingler, LS Levy - Pacific journal of mathematics, 2001 - msp.org
This is the first of a series of four papers describing the finitely generated modules over all
commutative noetherian rings that do not have wild representation type (with a possible …
