完美匹配单圈图的hyper-Wiener指标
Hyper-Wiener index of unicyclic graphs with perfect matchings
【摘要】 通过对连通图hyper-Wiener指标性质的研究,讨论了u+(2n)中hyper-Wiener指标的最小值,得到了达到最小hyper-Wiener指标的完美匹配单圈图的极图,并提出了关于hyper-Wiener指标的1个猜想.
【Abstract】 Some properties on the hyper-Wiener index of connected graphs are explored.These results can be used to determine the graph with minimum hyper-Wiener index among all graphs in u+(2n).Moreover,one comjecture on hyper-Wiener index of graphs is promoted.
