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(G)(u) . d(G)(v))d(G)(u, v) where d(G)(u) (or d(u)) is the degree of the vertex u of G, and d(G)(u, v) is the distance between u and v. Let U(n) be the set of unicyclic graph with n vertices. In this paper, we study the modified Schultz index of U(n) by introducing some transformations. Unicyclic graphs with the maximum ...
