A note on the construction of finitely injective modules

Rings and Algebras 2012-04-19 v1

Abstract

We develop a technique to construct finitely injective modules which are non trivial, in the sense that they are not direct sums of injective modules. As a consequence, we prove that a ring RR is left noetherian if and only if each finitely injective left RR-module is trivial, thus answering an open question posed by Salce.
