Discussion on the Medial Lemniscus,In this note we wish to study how some results concerning purity in abelian group theory can be extended to R-modules in general and to modules oyer Noetherian rings R, in particular. All rings are assumed to have an identity 1 and all modules are unitary left modules.

Discussion on Spinal Ascending Systems,Every group in this paper is an abelian p-group. We will observe some properties of abelian p-groups using topological 4methods.
