Demonstratio Mathematica, 2021 Abstract Let G be a group with identity e, R be a G-graded commutative ring with a nonzero unity 1, I be a graded ideal of R, and M be a G-graded R-module. In this article, we introduce the concept of graded I-second submodules of M as a generalization of graded second submodules of M and achieve some relevant outcomes.

Generalizations of graded second submodules [PDF]
Acta Universitatis Sapientiae, Mathematica, 2021 Abstract Let G be a group with identity e. Let R be a graded ring, I a graded ideal of R and M be a G-graded R-module. Let ψ: Sgr(M) → S gr(M) ∪ {∅} be a function, where Sgr(M) denote the set of all graded submodules of M. In this article, we introduce and study the concepts of graded ψ -second submodules and graded I-second submodules ...

Generalizations of second submodules
Filomat, 2020 In this paper, we introduce and study some new generalizations of second submodules via a function ? on the set of all submodules of a module. Let R be a ring with non-zero identity, M be an R-module and ? : S(M)? S(M) be a function where S(M) is the set of all submodules of M.
