给定独立数的连通图的无符号Laplace谱半径(英文)

The Spectral Radius of Signless Laplacian of a Connected Graph with Given Independence Number

本文刻画取得给定阶数和独立数连通图的谱半径最大值的图的结构,对特殊独立数也给出取得最小谱半径图的结构.

In this paper,we characterize the graphs with the maximal spectral radius of signless Laplacian among all graphs of fixed order and given independence number,and the graphs with the minimal spectral radius for some special independence number.
