摘要 通过对图进行收缩、夺邻、嫁接等运算,并利用Perron向量的一些性质,给出最大度为Δ(Δ≥3)的n(n≥5)阶极大邻接谱双圈图的一些性质,同时得到极大邻接谱双圈图的一些必要条件. By using the operations of contracting, moving neighbors, grafting and the properties of Perron vector, the prop- erties of the order n (n≥5) maximal-adjacency-spectrum bicyclic graphs with the maximum degree A (△≥3) are studied, and some necessary conditions about it are also obtained.
