Abstract

A graph in which atoms are taken as vertices and bonds can be shown by edges is called a molecular graph. For such graphs we can find the indices showing their bioactivity as well as their physio-chemical properties. Industry is flourishing nowadays just because of the interdisciplinary study of different subjects. This gives us a way to understand the application of different subjects. Chemical graph theory is a mixture of chemistry and mathematics both play an important role in chemical graph theory. Chemistry provides a chemical compound and graph theory transform this chemical compound into a molecular graph which further studied by different aspects such as topological indices. In this article, we computed generalized Randić, general Zagreb, general sum-connectivity, ABC, GA, $AB{C}_4,$ and $G{A}_5$ indices of line graphs of the $HA{C}_5{C}_7\left[p,q\right]$ and $V{C}_5{C}_7\left[p,q\right]$ nanotubes.”

摘要

以原子为顶点，键可用边表示的图称为分子图。对于这样的图表，我们可以找到显示它们的生物活性以及它们的物理化学特性的指数。当今工业蓬勃发展，正是因为不同学科的跨学科研究。这为我们提供了一种了解不同学科应用的方法。化学图论是化学和数学的混合体，在化学图论中都发挥着重要作用。化学提供了一种化合物，图论将这种化合物转化为分子图，通过拓扑指数等不同方面进一步研究。在本文中，我们计算了广义 Randić、广义 Zagreb、广义 sum-connectivity、ABC、GA、$\mathrm{一种}乙C_4,$和$G{\mathrm{一种}}_5$折线图的索引$H\mathrm{一种}{C}_5{C}_7\left[p,q\right]$和$五C_5{C}_7\left[p,q\right]$纳米管。”
