关于增广的Zagreb指数

On the Augmented Zagreb Index

Akbar Ali, Zahid Raza, Akhlaq Ahmad Bhatti

摘要:

拓扑指数在数学化学特别是定量结构-性质关系(QSPR)和定量结构-活性关系(QSAR)中起着重要的作用。最近的研究表明,增广萨格勒布指数(AZI)具有最好的相关能力,在几个拓扑指数。目前的研究的主要目的是建立一些数学性质的指数,或更准确地说,报告紧界的化学双环和化学单圈图的AZI。还得到了(补图连通的连通图的)AZI的一个Nordhaus-Gaddum型结果.

英文摘要:

Topological indices play an important role in mathematical chemistry especially in the quantitative structure-property relationship (QSPR) and quantitative structure-activity relationship (QSAR). Recent research indicates that the augmented Zagreb index (AZI) possess the best correlating ability among several topological indices. The main purpose of the current study is to establish some mathematical properties of this index, or more precisely, to report tight bounds for the AZI of chemical bicyclic and chemical unicyclic graphs. A Nordhaus-Gaddum-type result for the AZI (of connected graph whose complement is connected) is also derived.
