Abstract
Topological indices play a great role in Mathematical chemistry. Many graph theorists as well as chemists attracted towards these molecular descriptors. The aim of this paper is to introduce and investigate the Exponential Fraction index (a degree based Topological index). It is de ned as follows. EF(G) = X uv2E(G) e du dv : Here du and dv are the maximum and minimum degree respectively. In this paper, we calculate the Exponential Fraction index of double graphs, subdivision graphs and com- plements of some standard graphs. Also we compute the index for chemical structures Graphene and Carbon nanocones.
