摘要：

Let G = (V, E) be a simple connected graph, d(v) is the degree of vertex v, d(G)u, v) is the distance between u and v. The Schultz index of G is defined as W+ (G) = Sigma(u, v subset of V(G)) (d(u) + d(v))d(G) (u, v). In this paper, we investigate the Schultz index of a class tree with diameter not more than 4.
