Let R be a ring and , where and are the sets of all left and right zero-divisors of R, respectively. The zero-divisor graph of R, denoted by , is a simple undirected graph with vertex set , and two distinct vertices are adjacent if and only if ab = 0 or ba = 0. Let , the ring of integers modulo n, and the ring of all matrices over a finite field of q elements. In this article, using the technique on characteristic matrices, we give the value of fixing number of . Moreover, we calculate the fixing number and metric dimension of and .

固定与环关联的零除数图的数量和度量维度
设R是一个环并且, 在哪里 和 分别是R的所有左和右零除数的集合。的零因子图的[R ,记, 是一个带顶点集的简单无向图 , 和两个不同的顶点 相邻当且仅当ab = 0 或ba = 0。令, 整数环模n,和 所有人的戒指 q 个元素的有限域上的矩阵。在本文中,使用特征矩阵上的技术,我们给出了固定数量的值. 此外,我们计算了固定数和度量维数 和 .
