On Topological Indices of Multi-Walled Carbon Nanotubes

Abstract:

A molecular graph is a graph in which vertices are atoms of a given molecule and edges are its chemical bonds. A numerical quantity which characterizes the whole structure of a graph is called a topological index. Three degree based topological indices, the Randić (R α ), the atombond connectivity (ABC) and the geometric-arithmetic (GA) indices of multi-walled carbon nanotube networks are studied. Expressions for R α , ABC and GA indices for these important classes of networks are obtained.
