About this document
An Alternative Perspective On Injectivity of Modules by Nguyen quoc Tien is a document available to read on EtoBox.
The paper introduces the concept of N-subinjectivity for modules, defining a module M as N-subinjective if it allows for the extension of homomorphisms from N to M for any extension K of N. It explores the properties of subinjectivity domains and indigent modules, which are characterized as modules whose subinjectivity domain consists solely of injective modules. The study includes the existence of indigent modules in various ring families and establishes connections between indigent and poor modules.
