Combination of distance and symmetry in some molecular graphs


Suppose G is a connected graph or a union of connected graphs and is a subgroup of Aut(G). The modified Wiener index of G with respect to can be defined as follows: Ŵ (G) = |V (G)| 2| | ∑ u∈V (G) ∑ g∈ d(u, g(u)). In this article, this graph invariant for the cycle Cn with respect to all subgroups of Aut(Cn) is computed. As consequences, the modified Wiener… (More)
