Let R be a ring. M is said to be a minannihilator left R-module if r M l R (I)= IM for any simple
right ideal I of R. A right R-module N is called simple-flat if Nl R (I)= l N (I) for any simple right …

In this paper, we introduce Matlis flat modules as a generalization of copure flat modules
and give their characterizations. We prove that if R is a commutative Artinian ring and S⊂R …

The main purpose of this thesis is to study some classes of modules determined by neat,
coneat and s-pure submodules. A right R-module M is called neat-flat (resp. coneat-flat) if …

Let M be a left R-module, AA be a family of some submodules of M and BB be a family of
some left R-modules. In this article, we introduce and characterize A A-coherent, PA PA, FA …

Let $ M $ be a left $ R-$ module and $\pazocal {A}=\{A\} _ {A\in\pazocal {A}} $ be a family of
some submodules of $ M $. It is introduced the classes of (strongly) $ M-\pazocal {A} …
