Balaban index of an armchair polyhex, TUC4C8(R) and TUC4C8(S) nanotorus

摘要

The Balaban index of a graph G is defined as m/(mu + 1)Sigma(e=uv) [d(u)d(v)](-0.5), where m is the number of edges of G, mu is the cyclomatic number of G and for every vertex x of G, d(x) is the summation of distances between x and all vertices of G. In this paper, the Balaban index of an armchair polyhex, TUC4C8(R) and TUC4C8(S) nanotorus are computed.
