摘要

受高阶连通性指数(或Randic指数)的化学应用的启发，我们在这里考虑分子图的高阶第一萨格勒布指数。本文研究了辛烷同分异构体的熵和无中心因子对二阶一萨格勒布指数的线性回归分析。基于二阶第一萨格勒布指数的线性模型优于第一萨格勒布指数和f指数对应的模型。进一步，我们计算了二维晶格、纳米管和纳米环面的细分图的折线图的二阶一萨格勒布指数[p];、蝌蚪图、轮图、梯图。

On the second order first zagreb index

Inspired by the chemical applications of higher-order connectivity index (or Randic index), we consider here the higher-order first Zagreb index of a molecular graph. In this paper, we study the linear regression analysis of the second order first Zagreb index with the entropy and acentric factor of an octane isomers. The linear model, based on the second order first Zagreb index, is better than models corresponding to the first Zagreb index and F-index. Further, we compute the second order first Zagreb index of line graphs of subdivision graphs of 2D-lattice, nanotube and nanotorus of TUC4C8[p; q], tadpole graphs, wheel graphs and ladder graphs.
