Attached submodules of module

Prime ideals and primary decompositions have an important role in ring theory. On the other hand, dual of the theory of primary decompositions of submodules is developed. This theory is named secondary decomposition. Second modules recently are defined by an Iranian mathematicion. In this paper, we investigate the theory of attached submodules of modules.
