Absolutely pure modules
KR Pinzon - 2005 - uknowledge.uky.edu
Absolutely pure modules act in ways similar to injective modules. Therefore, through-out this
document we investigate many of these properties of absolutely pure modules which are …

On covers and envelopes in some functor categories
L Mao - Communications in Algebra, 2013 - Taylor & Francis
We study the existence of covers and envelopes by some special functors on the category of
finitely presented modules. As an application, we characterize some important rings using …

The phantom cover of a module
I Herzog - Advances in Mathematics, 2007 - Elsevier
A morphism f: M→ N of left R-modules is a phantom morphism if for any morphism g: A→ M,
with A finitely presented, the composition fg factors through a projective module …

Auslander–Bridger modules
A Facchini, N Girardi - Communications in Algebra, 2012 - Taylor & Francis
Classically, the Auslander–Bridger transpose finds its best applications in the well-known
setting of finitely presented modules over a semiperfect ring. We introduce a class of …

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 …
