Abstract

‎Let $R$ be a commutative ring with‎
‎identity and $M$ be an $R$-module‎.
‎In this paper‎, ‎we introduce and investigate the second submodule intersection graph $SSI(M)$ of $M$ with vertices‎
‎are non-zero proper submodules of $M$ and two distinct vertices $N$ and $K$ are adjacent if and only if $N \cap K$ is a second submodule of $M$‎. ‎Also‎, ‎we introduce and consider the prime submodule sum graph $PSS(M)$ of $M$ with vertices‎
‎are non-zero proper submodules of $M$ and two distinct vertices $N$ and $K$ are adjacent if and only if $N‎ + ‎K$ is a prime submodule of $M$‎.
