On Reverse Eccentric Connectivity Index of One Tetragonal Carbon Nanocones

Nejati A and Mehdi A

Let be a molecular graph. The reverse eccentric connectivity index is defined as ( ) ( ) =RE c ( ) = ( ) u V G u REEC G G ecc u S ξ ∈ Σ , where ecc(u) is the largest distance between u and any other vertex v of molecular graph G and Su is the sum of the degrees of all vertices v, adjacent to vertex u. In this paper, an exact formula for the reverse eccentric connectivity index of one tetragonal carbon nanocones was computed.
