A submoduleA of amodule M is said to be strongly pure , if for each finite subset {a i } in A , (equivalently, for each a A) there exists ahomomorphism f : M A such that f(a i ) = a i , i(f(a)=a). A module M is said to be strongly F-regular if each submodule of M is strongly pure . The main purpose of this paper is to develop the properties of strongly F-regular modules and study modules with the property that the intersection of any two strongly pure submodules is strongly pure .
In this paper , we introduce * relation on the Lattic of submodules of a module M. We say that submodule X ,Y of M are * equivalent , X * Y, if + + and + + ,for some H≪TM .We show that * relation is an equivalence relation and has good behavior with respect to addition of submodules and homomorphisms. This relation is used to define and study the class of Goldie*-T-lifting modules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
