The first general Zagreb (FGZ) index (also known as the general zeroth-order Randić index) of a graph can be defined as , where is a real number. As is equal to the order and size of when and , respectively, is usually assumed to be different from 0 to 1. In this paper, for every integer , the FGZ index is computed for the generalized F-sums graphs which are obtained by applying the different operations of subdivision and Cartesian product. The obtained results can be considered as the generalizations of the results appeared in (IEEE Access; 7 (2019) 47494–47502) and (IEEE Access 7 (2019) 105479–105488).

广义F和图的第一一般Zagreb索引

图表的第一个通用Zagreb（FGZ）索引（也称为通用零阶Randić索引）可以定义为，哪里是实数。如等于的顺序和大小时 和 ，分别通常假定为从0是不同的为1。在本文中，为每一个整数，针对通过应用细分和笛卡尔积的不同运算而获得的广义F和图，计算FGZ指数。获得的结果可视为（IEEE Access; 7（2019）47494-47502）和（IEEE Access 7（2019）105479-105488）中出现的结果的概括。
