چکیده
|
Let g be a simple connected graph. the edge-wiener index we(g) is the sum of all distances between edges in g, whereas the hyper edge-wiener index w we(g) is defined as w we(g) = 1/2 w^2 e(g) + 1/2 w^2 e (g), where w^2 e (g) = ∑ {f,g} ⊆e(g) d^2 e (f, g). in this paper, we present explicit formula for the hyper edge-wiener index of corona product of two graphs. also, we use it to determine the hyper edge-wiener index of some chemical graphs.
