Extremal Graph of the Wiener Index of Graphs with Given Number of Suspension Points
摘要
Abstract
Let be a simple graph, the Wiener index of is the sum of distances between all pairs of vertices of . In this paper, we characterize the extremal graph with the first, the second and the third smallest Wiener index among all graphs with given order and the number of suspension points, and give the lower bounds of the Wiener index of graphs with given number of suspension point.关键词
