Generalizations of perfect, semiperfect, and semiregular rings
Y Zhou - Algebra colloquium, 2000 - Springer
For a ring R and a right R-module M, a submodule N of M is said to be δ-small in M if,
whenever N+ X= M with M/X singular, we have X= M. If there exists an epimorphism p: P→ M …
whenever N+ X= M with M/X singular, we have X= M. If there exists an epimorphism p: P→ M …
