%X Paper pages (271-276) Introduction Throughout this paper, will denote a commutative ring with identity and will denote the ring of integers. Let be an -module. A submodule of is said to be pure if for every ideal of . has the copure sum property if the sum of any two copure submodules is again copure. is said to be a comultiplication module if for every submodule of there exists an ideal of such that . satisfies the double annihilator conditions if for each ideal of , we have . is said to be a strong comultiplication module if is a comultiplication R-module which satisfies the double annihilator conditions. A submodule of is called fully invariant if for every endomorphism ,. In [5], H. Ansari-Toroghy and F. Farshadifar introduced the dual notion of pure submodules (that is copure submodules) and investigated the first properties of this class of modules. A submodule of is said to be copure if for every ideal of . Material and methods We say that an -modulehas the copure intersection property if the intersection of any two copure submodules is again copure. In this paper, we investigate the modules with the copure intersection property and obtain some related results. Conclusion The following conclusions were drawn from this research. Every distributive -module has the copure intersection property. Every strong comultiplication -module has the copure intersection property. An -module has the copure intersection property if and only if for each ideal of and copure submodules of we have If is a , then an -module has the copure intersection property if and only if has the copure sum property. Let , where is a submodule of . If has the copure intersection property, then each has the has the copure intersection property. The converse is true if each copure submodule of is fully invariant../files/site1/files/62/12Abstract.pdf
