给定悬挂点数的树的α-Sombor指数研究
Study on Sombor Index of A Tree with A Given Number of Hanging Points
摘要
Abstract
The α-Somobr index of the figure G is defined as SOα(G)=∑ xy∈E(G)(d2G(x)+d2G(y))α,WheredG(x)is the degree of the point xin graph G.This paper mainly considers when the α>1 the maximum α-Somobr index of the tree with a given number of hanging points.Additionally,the maximum α-Somobr index of the tree is determined and the polar graph is described in this paper.关键词
