本文证明了如下结果:左 R-模 M是局部 Noether模当且仅当σ[M]中的任意M-内射左R-模的直和是一个有限余生成左R-模和一个拟连续(或连续,直内射)左R-模的直和.
This paper is devoted to give some characterizations of locally noetherian modules by finitely cogenerated modules and generalized injective modules. It is proved that a left R-module M is locally noetherian if and only if every direct sum of M-injective left R-modules in σ[M] is the direct sum of a finitely cogenerated left R-module and a quasi-continuous (or, continuous, or, direct-injective, etc,) left R-module.
