单圈图的极小ABC指数
The Minimal Atom-bond Connectivity Index of Unicyclic Graphs
摘要
Abstract
In this paper,we give the structural properties of the extremal graphs which attain the minimal ABC index of unicyclic graphs.By graph transformations and fractional comparison,we give the relation between the tricyclic graphs of order n and the extremal graphs which attain the minimal ABC index of unicyclic graphs of order n.关键词
