چکیده
|
For the edge e = uv of a graph g, let nu = n(u|g) be the number of vertices of g lying closer to the vertex u than to the vertex v and nv= n(v|g) can be defined simailarly. then the abcgg index of g is defined as abcgg =sum_{e=uv} sqrt{f(u,v)}, where f(u,v)= (nu+nv2)/nunvthe aim of this paper is to give some new results on this graph invariant. we also calculate the abcgg of an infinite family of fullerenes.
