摘要
Let G be a connected simple graph. The hyper-Wiener index WW (G) is defined as WW (G) =1/2 Sigma(u,v is an element of V(G)) (d(u, v) + d(2) (u, v)), with the summation going over all pairs of vertices in C. In this paper, we determine the extremal unicyclic graphs with given matching number and minimal hyper-Wiener index.
