非负矩阵Hadamard积的谱半径的新界

New Bounds on the Spectral Radius of Hadamard Product of Nonnegative Matrices

文章研究非负矩阵A和B的Hadamard积的谱半径的界的问题,利用带有参数的新的圆盘定理,通过给予参数恰当的调节,得到了谱半径的新估计式。

In this paper,we study the bounds of spectral radius of Hadamard product of nonnegative matrix sums,using the new disk theorem with parameters.By giving the parameters the proper adjustment,a new estimate of spectral radius is obtained.
