摘要：
The atom-bond sum-connectivity (ABS) index of a given graph G is symbolized with ABS and define by sum of the weights root d(u) + d(v)(-2)/d(u) + d(v) , where d(u) is the degree of a vertex u in G. In this paper, the extremal atom-bond sum-connectivity index among all n-vertex chemical trees, connected chemical unicyclic graphs, connected chemical bicyclic graphs, and connected chemical tricyclic graphs, were determined.
