摘要
本文探讨模同态广义逆在环模理论中的应用.利用模同态的{1}-逆和{2}-逆,分别给出了一类环及一类重要模的特征刻画.
This note is a contribution to the application of generalized inverse of homomorphisms of modules in ring (module) theory. Using the {1}- and {2}-inverses of homomorphisms of modules, we characterize a class of rings and an important class of modules respectively.
