On Red-Supplemented Modules, Weak Red-Supplemented Modules and Completely Weak Red-Supplemented Modules

In this paper some results that concerning localization of modules are proved. Italso, studies the effect of localization on certain types of modules such assupplemented modules, weak supplemented modules and completelyweak supplemented modules. Several conditions are given under whichcertain properties of such types of algebraic structures are preserved underlocalization.
