关于广义Sierpinski图的距离

On distances in generalized Sierpinski graphs

Alejandro Estrada-Moreno, Erick D. Rodriguez-Bazan, Juan A. Rodriguez-Velazquez

摘要:

在本文中,我们提出了一个广义Sierpienski图$S(G,t)$的顶点之间的距离公式的基础图$G$的顶点之间的距离。特别地,我们推导出了$S(G,t)$的任意顶点与极点之间距离的递推公式,并在基图为无三角形的情况下,得到了$S(G,t)$的任意两个顶点之间距离的递推公式.从这些递归公式,我们提供的算法来计算$S(G,t)$的顶点之间的距离。此外,当基图是树时,我们给出了$S(G,t)$的直径和半径的显式公式。

英文摘要:

In this paper we propose formulas for the distance between vertices of a generalized Sierpiński graph $S(G,t)$ in terms of the distance between vertices of the base graph $G$. In particular, we deduce a recursive formula for the distance between an arbitrary vertex and an extreme vertex of $S(G,t)$, and we obtain a recursive formula for the distance between two arbitrary vertices of $S(G,t)$ when the base graph is triangle-free. From these recursive formulas, we provide algorithms to compute the distance between vertices of $S(G,t)$. In addition, we give an explicit formula for the diameter and radius of $S(G,t)$ when the base graph is a tree.
