A theorem due to Nakayama and Skornyakov states that “a ring R is an Artinian serial ring if and only if all left R -modules are serial” and a theorem due to Warfield state that “a Noetherian ring R is serial if and only if every finitely generated left R -module is serial”. We say that an R -module M is prime uniserial ( ℘ - uniserial , for short) if for every pair P , Q of prime submodules of M either P ⊆ Q or Q ⊆ P , and we say that M is prime serial ( ℘ - serial , for short) if it is a direct sum of ℘ -uniserial modules. Therefore, two interesting natural questions of this sort are: “Which rings have the property that every module is ℘ -serial?” and “Which rings have the property that every finitely generated module is ℘ -serial?” Most recently, in our paper, Prime uniserial modules and rings (submitted), we considered these questions in the context of commutative rings. The goal of this paper is to answer these questions in the case R is a Noetherian ring in which all idempotents are central or R is a left Artinian ring.
