چکیده
|
The atom-bond connectivity index of graph is a topological index proposed by estrada et al.as abc (g) ? ?uv?e (g ) (du ?dv ? 2) / dudv , where the summation goes over all edges ofg, du and dv are the degrees of the terminal vertices u and v of edge uv. in the present paper,some upper bounds for the second type of atom-bond connectivity index are computed.
