摘要
对最大特征值的上下界进行估计是非负矩阵理论的重要部分,借助两个新的矩阵,从而得到一个判定非负矩阵最大特征值范围的界值定理,其结果比有关结论更加精确.
Computing the bounds for the greatest eigenvalue is an important part in the theory of nonnegative matrices. In this paper, we obtained new bounds for the greatest eigen- value of nonnegative matrices by two new matrices. Compared with the relevant conclusions, the new bounds are more accurate.
