p-拟k-循环图的最大Zagreb指数

Maximum Zagreb Indices Among All p-Quasi k-Cyclic Graphs

A Ghalavand, A R Ashrafi

摘要:

一个简单连通图G称为p-拟k-圈图,如果存在顶点子集S使得|S| =p,G-S是k-圈的,且不存在V(G)的子集S`使得|S`|< |S|和G-S '是k-循环的。本文的目的是在k ≥ 3的p-拟k-圈图中刻画出Zagreb指标具有最大值的图.

英文摘要:

A simple connected graph G is called a p-quasi k-cyclic graph, if there exists a subset S of vertices such that |S|=p, G-S is k-cyclic and there is no a subset S` of V(G) such that |S`|<|S| and G-S` is k-cyclic. The aim of this paper is to characterize graph with maximum values of Zagreb indices among all p-quasi k-cyclic graph of order k>=3.
