摘要：
The atom-bond connectivity index of a graph G is defined as ABC(G) = Sigma(uv is an element of E(G)) root d(u) + d(v) - 2/d(u) d(v) where E(G) is the edge set and d(u), d(v) are the degrees of the vertices u and v in G, respectively. We characterize the trees with given degree sequences, extremal w. r. t. the ABC index.
