This article investigates the concept of dominant metric dimensions in zero divisor graphs (ZD-graphs) associated with rings. Consider a finite commutative ring with unity, denoted as , where nonzero elements and are identified as zero divisors if their product results in zero The set of zero divisors in ring is referred to as . To analyze various algebraic properties of , a graph known as the zero-divisor graph is constructed using This manuscript establishes specific general bounds for the dominant metric dimension (Ddim) concerning the ZD-graph of . To achieve this objective, we examine the zero divisor graphs for specific rings, such as the ring of Gaussian integers modulo , denoted as the ring of integers modulo , denoted as , and some quotient polynomial rings. Our research unveils new insights into the structural similarities and differences among commutative rings sharing identical metric dimensions and dominant metric dimensions. Additionally, we present a general result outlining bounds for the dominant metric dimension expressed in terms of the maximum degree, girth, clique number, and diameter of the associated ZD-graphs. Through this exploration, we aim to provide a comprehensive framework for analyzing commutative rings and their associated zero divisor graphs, thereby advancing both theoretical knowledge and practical applications in diverse domains.
