摘要

摘要设G=(V,E)是一个具有顶点集V和边集E的简单连通图。G的塞格德指数定义为，其中，分别表示离u更近的G的顶点数(分别为v)比离u更近的G的顶点数(分别为u)。如果‎‎‎‎‎‎‎年代的‎‎‎‎‎大小设置‎‎‎‎让‎‎‎V组是‎‎‎‎‎‎所有子集的‎‎‎‎‎大小3。然后我们定义了具有顶点集v的相交图的三种类型，这些图用表示，我们将找到它们的塞格德指数

Computing Szeged Index of Graphs on Triples

ABSTRACT Let ‎G=(V,E) ‎be a‎ ‎simple ‎connected ‎graph ‎with ‎vertex ‎set ‎V‎‎‎ ‎and ‎edge ‎set ‎‎‎E. ‎The Szeged index ‎of ‎‎G is defined by ‎ where ‎ respectively ‎ ‎ is the number of vertices of ‎G ‎closer to ‎u‎ (‎‎respectively v)‎ ‎‎than ‎‎‎v (‎‎respectively u‎).‎ ‎‎If ‎‎‎‎S ‎is a‎ ‎set ‎of ‎size‎ ‎ ‎ ‎let ‎‎V ‎be ‎the ‎set ‎of ‎all ‎subsets ‎of ‎‎S ‎of ‎size ‎3. ‎Then ‎we ‎define ‎three ‎‎types ‎of ‎intersection ‎graphs ‎with ‎vertex ‎set V. These graphs are denoted by ‎‎ ‎‎ and we will find their ‎Szeged ‎indices.‎
