Commutative Algebra 2022-06-01 v1

Abstract

In this paper, we prove that a finitely embedded RR-module MM is Artinian if and only if for every prime ideal p\mathfrak{p} of RR with (0:RM)p(0:_RM)\subseteq \mathfrak{p}, there exists a submodule NpN^\mathfrak{p} of MM such that M/NpM/N^\mathfrak{p} is finitely embedded and M[p]Np(0:Mp)M[\mathfrak{p}]\subseteq N^\mathfrak{p}\subseteq (0:_M\mathfrak{p}).
