摘要:
针对非负矩阵的Kronecker积谱半径界的估计问题,本文在Frobenius界、Ledermann界、Ostrowski界和Brauer界的基础上推广了若干定理。并且结合具体实例说明:当非负矩阵阶数较大时,用Ostrowski界和Brauer界推广的定理求解精度更高,计算量更小。

Abstract:
In view of the problem of the bounds on spectral radius of Kronecker product of nonnegative matrices, extended several theorems based on Frobenius Boundary, Ledermann Boundary, Ostrowski Boundary and Brauer Boundary. And Using specific example shows that when the order numbers of nonnegative matrices are larger, using the two extended theorems from Ostrowski Boundary and Brauer Boundary may promote higher accuracy and less calculation.
