摘要
用H(a,b11,b12,b21,b22)表示具有n个顶点的四叶树。图G的Hosoya指标定义为G的独立边子集的总数目。本文讨论了四叶树Hosoya指标的第三小值。
Let H(a,b11,b12,b21,b22)denote a Four-leaf tree with n vertices.Graph G is defined as the total number of independent edge set of Hosoya index.In the paper,the third minimal Hosoya index of four-leaf tree is discussed.
