• F-INDICES OF CHEMICAL NETWORKS

Abstract

In Chemical Sciences, a forgotten topological index or F-index has significant importance to collect information about properties of chemical compounds. In this paper, we introduce the second F-index, second hyper F-index, the general first and second F-indices, sum connectivity F-index and product connectivity F-index of a graph. We compute the first and second F-indices, first and second hyper F-indices and their polynomials of armchair polyhex, zigzag polyhex and carbon nanacone networks. Furthermore, we determine the sum connectivity F-index and product connectivity F-index of these networks.
