点粘接双圈图是指两个圈有一个公共的顶点的图.根据已有的结果,通过对Hosoya指标的理论和性质的研究,给出了点粘接双圈图Hosoya指标的最大值序列及其最大值的图.
Bicyclical graphs with dot bonding is a graph which two graphs have a common vertex.Based on the recent research achievements,the theories and properties of Hosoya index were studied and maximal order and extreme graphs of Hosoya index of bicyclical graphs with dot bonding were given.
