چکیده مقاله
A map taking graphs as arguments is called a graph invariant or topological index if it assigns equal values to isomorphic graphs. A fullerene molecule C_n is a closed cage carbon molecule with three coordinate carbon atoms tiling the spherical or nearly spherical surface formed by 12 pentagonal and n/2 – 10 hexagonal rings. The carbon nanotubes are new allotropes of carbon with a cylindrical nanostructure. In this talk, a new algorithm for computing distancebased topological indices of these anomaterials is presented. We apply our algorithm to compute the vertex and edge revised Szeged indices of these nanomaterials.
