本文利用图及其补图的无符号拉普拉斯距离谱半径分别给出了一个图包含Hamilton路、Hamilton圈以及是Hamilton连通图与泛圈图的充分条件。
In this paper, we study sufficient conditions for a graph and its complement having a Hamiltonian path , Hamiltoni-an cycle, or being Hamilton -connected graph and pancyclic graph by its distance signless Laplacian spectral radius.
