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-coinvariant

Modules close to the automorphism-invariant and coinvariant where some well-known results on essentially injective modules, automorphism-(co)invariant modules

Modules which are invariant under nilpotents of their envelopes and covers(M/Z(M)) > 1 is nilpotent-invariant iff it is injective. We also study nilpotent-coinvariant modules

Dual automorphism-invariant modules over perfect rings© 2017, Pleiades Publishing, Ltd. Under study are the dual automorphism-invariant modules

Rings Whose Every Right Ideal is a Finite Direct Sum of Automorphism-Invariant Right Ideals sum of automorphism-invariant right R-modules. These rings are called right Σ-a-rings. We find a

Rings all of whose finitely generated ideals are automorphism-invariantRings in which each finitely generated right ideal is automorphism-invariant (rightfa

Modules close to SSP- and SIP-modulesIn this paper, we investigate some properties of SIP, SSP and CS-Rickart modules. We give
