A generalization of semiregular and semiperfect modules
Let U be a submodule of a module M. We call U a strongly lifting submodule of M if
whenever M/U=(A+ U)/U⊕(B+ U)/U, then M= P⊕ Q such that P≤ A,(A+ U)/U=(P+ U)/U and …

[PDF][PDF] Cofinitely δ-supplemented and cofinitely δ-semiperfect modules
K Al-Takhman - International Journal of Algebra, 2007 - researchgate.net
In this work, we prove that an R-module M is cofinitely δ-supplemented (ie each cofinite
submodule of M has a δ-supplement) if and only if every maximal submodule of M has a δ …

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 …
