There are various methods available which are used to search large chemical databases and to predict the physicochemical properties of molecular structures. Using molecular descriptors for this purpose is the simplest of these methods. The Zagreb indices are amongst the oldest molecular descriptors, and their properties have been extensively studied and applied in QSAR/QSPR studies. The Zagreb coindices were recently introduced, attracting the attention of researchers in mathematical chemistry. In this paper, we study Zagreb indices and several other Zagreb-type indices including the general Randic index, sum-connectivity index, F-index, and Zagreb coindices of - vertex and edge join of two arbitrary graphs.

有多种方法可用于搜索大型化学数据库和预测分子结构的物理化学性质。为此目的使用分子描述符是这些方法中最简单的方法。萨格勒布指数是最古老的分子描述符之一，其特性已被广泛研究并应用于 QSAR/QSPR 研究。最近引入了萨格勒布 coindices，引起了数学化学研究人员的注意。在本文中，我们研究了 Zagreb 指数和其他几个 Zagreb 型指数，包括一般 Randic 指数、sum-connectivity 指数、F-index 和 Zagreb coindices of - 两个任意图的顶点和边连接。
