摘要:

设$G$是$n$顶点上的连通图,$D(G)$是它的距离矩阵.当图是树或{a}单圈图时,用顶点数计算这个矩阵的行列式的公式是已知的。在这项工作中,我们推广了这些结果,得到的距离矩阵的行列式的{所有图}在{类,包括树,单圈和双圈图。这类图实际上包括具有许多圈的图,只要图的每个块至多是双环。

英文摘要:

Let $G$ be a connected graph on $n$ vertices and $D(G)$ its distance matrix. The formula for computing the determinant of this matrix in terms of the number of vertices is known when the graph is either a tree or {a} unicyclic graph. In this work we generalize these results, obtaining the determinant of the distance matrix for {all graphs} in a {class, including trees, unicyclic and bicyclic graphs. This class actually includes graphs with many cycles, provided that each block of the graph is at most bicyclic.}
