Abstract Topological indices are numerical numbers associated to molecular graphs and are invariant of a graph. In QSAR/QSPR study, Zagreb indices are used to explain the different properties of chemical compounds at the molecular level mathematically. They have been studied extensively due to their ease of calculation and numerous applications in place of the existing chemical methods which needed more time and increased the costs. In this paper, we compute precise values of new versions of Zagreb indices for two classes of dendrimers.

计算一些树枝状聚合物结构的整个萨格勒布指数

摘要 拓扑指数是与分子图相关的数字，并且是图的不变性。在 QSAR/QSPR 研究中，萨格勒布指数用于在分子水平上以数学方式解释化合物的不同性质。由于它们易于计算和替代需要更多时间和增加成本的现有化学方法的大量应用，它们已被广泛研究。在本文中，我们计算了两类树枝状聚合物的新版本萨格勒布指数的精确值。
