摘要
对Brauer定理中谱半径的上界估计进行了修改,给出了一种新估计。并通过算例表明了修改的Brauer定理对谱半径的上界估计比原估计要更接近真值。
By modifying the estimation of upper for spectral radius in Brauer theorem , a new estimation is given. A example shows that the new estimation of upper for spectral radius in M-Brauer theorem is superior than the Brauer theorem.
