摘要

The Wiener index W (G) = ∑_(u,v) sub set V(G)) d(u, v), the hyper-Wiener index WW (G) = 1/2 ∑_(u,v) sub set V(G)) [d(u, v) + d~2(u, v)] and the reverse-Wiener index ∧(G) = n(n-1)D/2 — W(G), where d(u, v) is the distance of two vertices u, v in G, d~2 (u, v) = d(u, v)~2, n = |V(G)| and D is the diameter of G. In [M. Eliasi, B. Taeri, Four new sums of graphs and their Wiener indices, Discrete Appl. Math. 157 (2009) 794─803], Eliasi and Taeri introduced the F-sums of two connected graphs. In this paper, we determine the hyper- and reverse-Wiener indices of the F-sum graphs and, subject to some condition, we present some exact expressions of the reverse-Wiener indices of the F-sum graphs.
