摘要
本文利用了Cassini卵形域,给出了非负矩阵Hadamard积的最大特征值的上界、M-矩阵Fan积的最小特征值的下界以及M-矩阵与其逆矩阵Hadamard积最小特征值的下界.理论分析表明本文获得的结果比相应文献中的结果更精确.
A new upper bound on the spectral radius is obtained by using Cassini oval. Meanwhile, a new lower bound on the smallest eigenvalue for the Fan product and a new lower bound on the minimum eigenvalue for the Hadamard product of two nonsingular matrices are given. Theoretically, these results are more accurate than the results in the literature.
