摘要
研究Euler-Sombor指数的目的不单纯是对已有的Sombor指数概念进行推广、修改和变形,而是为了探索其新的性质和边界.借助不等式理论,利用数学分析的方法,用图的顶点度刻画了图的Euler-Sombor指数的上界,得到了几个有意义的结果.
The purpose of studying the Euler-Sombor index is not merely to extend,modify or transform the existing Sombor index concept,but to explore its new properties and boundaries.In this paper,by means of inequality theory and using mathematical analysis methods,the upper bound problem of the Euler-Sombor index of a graph is characterized by the degree of the graph’s vertices,and several innovative results are obtained.
