On the structure of modules defined by opposites of FP injectivity
Let R be a ring with unity and let MR and RN be right and left modules,respectively. The module MR is said to be absolutely RN-pure if M circle times NL circle times N is amonomorphism for every extension LR of MR. For a ...
On the structure of modules defined by subinjectivity
(World Scientific Publishing Company, 2019-10)
The aim of this paper is to present new results and generalize some results about indigent modules. The commutative rings whose simple modules are indigent or injective are fully determined. The rings whose cyclic right ...
