A Note on Projective Modules

Commutative Algebra 2020-11-17 v1

Abstract

This expository note delves into the theory of projective modules parallel to the one developed for injective modules by Matlis. Given a perfect ring RR, we present a characterization of indecomposable projective RR-modules and describe a one-to-one correspondence between the projective indecomposable RR-modules and the simple RR-modules.
