几类积图的Sombor指标
Sombor Index of Several Kinds of Product Graphs
摘要
Abstract
Sombor index is a new topological index based on vertex degree introduced by Gutman in Chemical Graph Theory.In this paper,Sombor indices of cartesian products of path Pn with fan graph Fm and wheel graph Wm,wheel graph Wn with fan graph Fm and wheel graph Wm,fan graph Fn with fan graph Fm,and lollipop graph Na,b,barbell graph Da,b,c and kite graph La,b with complete graph Kn are discussed,Sombor indices of Direct products,Cartesian products and Strong products of complete graph,path and cycleare are also studied and the exact index values and some relations of sombor indices about product graph are obtained.关键词
