Almost Projective and Almost Injective Modules injective is clarified. The regular and I-finite rings over which every right module is almost projective
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
On rings with cyclic almost-injective modulesIt is shown that every finitely generated right R-module is almost injective if and only if every
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.
Rings Characterized via Some Classes of Almost-Injective Modules cyclic module is almost-injective (CAI). It is shown that R is an Artinian serial ring with J(R) 2= 0
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
Laser beam modulation using corner reflector and deep diffraction grating modulation of the zero-order diffraction beam at a modulation depth of almost 100% and a relatively high
