Topological Symmetry of Nanostructures

Abstract

A molecular graph is a graph in which vertices are atoms and edges are chemical bonds. In this paper, we describe a method for computing the symmetry of some giant carbon molecules. Some conjectures and open questions are also presented.

Keywords:

• Topological symmetry
