Web28 de mai. de 2009 · Then the Wiener index of G with respect to c is W ( G, c) = ∑ { x, y } ⊆ V c ( x) c ( y) d ( x, y). We note that for c ≡ 1 this yields the usual Wiener index, while for c ( x) = deg ( x) we obtain the Gutman index. The edge-Wiener index of a graph is connected to its Gutman index by the following inequality. Theorem 5.
