| چکیده | ||
| Given a commutative ring $R$, a left $R$-module $M$, and an $R$-submodule $N \subseteq M$, the graph $G(R;M,N)$, induced on $R$ by the pair $(M,N)$, is a simple graph with vertex set $R^* = R \backslash \{0\}$. Distinct vertices r and s are adjacent if $rsN = 0$. This graph generalizes Beck's zero-divisor graph $G(R)$. We analyze connectivity, completeness, bipartiteness, cycles, diameter, girth, independence/clique/chromatic numbers, and domination numbers, often under specific algebraic constraints on $R$ or $N$. Applications to $\mathbb Z_n$-modules illustrate these results. By linking $G(R;M,N)$ to $G(R)$, we derive graph invariants for $G(R)$ efficiently and vice versa, deepening insights into algebraic structures and their graph-theoretic analogs. | ||
