Direct Projective Modules, Direct Injective Modules, and their GeneralizationsThis paper contains new and previously known results on modules that are close to direct projective

Semilocal group algebras, then every finitely generated flat k[G]-module is projective. © 2005 Springer Science+Business Media, Inc.

Almost Projective and Almost Injective Modules
injective is clarified. The regular and I-finite rings over which every right module is almost projective

Modules that are Invariant with Respect to Automorphisms and Idempotent Endomorphisms of Their Hulls and CoversThe paper contains both known and new results on automorphism-invariant modules, automorphism

Fully idempotent homomorphismsFor arbitrary modules A and B we introduce and study the notion of a fully idempotent Hom (A, B

Modules close to the automorphism-invariant and coinvariant and small projective modules can be obtained by developing a general theory of modules which are (co

Rings over which every module is an I*0-module projective module and a V -module.

CS-Rickart modules n ∈ N. We show that every finitely generated projective right R-module will to be a CS

CS-Rickart modules describe the rings over which each finitely generated projective module is CS-Rickart module. The presented
