讨论了点数和最大度均固定的一类树的谱半径,分别给出了这类树的谱半径的上界和下界,并分别刻画了达到上下界的极图.
This paper discussed the spectral radius of trees with fixed number of vertices and fixed maximal degree, and gave the upper bound and lower bound of the spectral radius of those trees respectively. Furthermore, the minimal spectral radius were obtained at trees T^1△, T△ and T^*△.
