Let Ube an associative ring with 1, and M a left U-module.We consider the modules by the generalized inverses of homomorphisms, and we classify the modules with the regular inverses of homomorphisms.We make some necessary and sufficient conditions for a module to be direct injective, indecomposable, strongly indecomposable respectively.
