On $Gr$-$C$-$2^{A}$-secondary submodules
Let $Ω$ be a group with identity $e$, $Γ$ be a $Ω$-graded commutative ring and $\Im$ a graded $Γ$-module. In this article, we introduce the concept of $gr$-$C$-$2^{A}$-secondary submodules and investigate some properties of this new class of graded submodules. A non-zero graded submodule $S$ of $\Im$ is said to be a $gr$-$C$-$2^{A}$-secondary submodule if whenever $r,s \in h(Γ)$, $L$ is a graded submodule of $\Im$, and $rs\,S\subseteq L$, then either $r\,S\subseteq L$ or $s\,S \subseteq L$ or $rs \in Gr(Ann_Γ(S))$.
