摘要
For a graph G = (V, E), the modified Schultz index of G is defined as S*(G) = Sigma({u,) (v}subset of V(G))(d(u). d(v))d(G)(u, v) where d(u) (or d(v)) is the degree of the vertex u (or v) of G, and d(G)(u, v) is the distance between a and v. Explicit formulas for calculating the modified Schultz index of armchair polyhex nanotubes are provided in this paper.
