Delta Geometric-Arithmetic and Delta Arithmetic-Geometric Indices of Certain Nanotubes and Networks

Abstract

In this study, we introduce the delta geometric-arithmetic index and the delta arithmetic-geometric index and their corresponding polynomials of a graph. Furthermore we present the computational formulas for calculating the delta geometric-arithmetic index and the delta arithmetic-geometric index and corresponding their polynomials of two families of nanotubes and two families of networks.
