Rings Whose Cyclic Modules Are Direct Sums Of Extending Modules
(Cambridge Univ Press, 2012)
Dedekind domains, Artinian serial rings and right uniserial rings share the following property: Every cyclic right module is a direct sum of uniform modules. We first prove the following improvement of the well-known ...
An Alternative Perspective on Injectivity of Modules
(Academic Press Inc Elsevier Science, 2011)
Given modules M and N, M is said to be N-subinjective if for every extension K of N and every homomorphism : N M there exists a homomorphism phi : K -> M such that phi vertical bar N = phi. For a module M, the subinjectivity ...
Almost-Perfect Modules
(Cambridge Univ Press, 2010)
We call a module M almost perfect if every M-generated flat module is M-projective. Any perfect module is almost perfect. We characterize almost-perfect modules and investigate some of their properties. It is proved that ...
