特殊矩阵特征值新的Weyl型扰动上界

摘要

Using the singular value decomposition, some new Weyl type absolute perturbation bounds of symmetrizable matrix are obtained. We get the results, which improve and extend the correspond-ing results in other papers.%利用矩阵的分解及矩阵的计算技巧,得到了可对称化矩阵特征值新的Weyl型绝对扰动上界,推广了以往的结果,并在此基础上推广了Kahan定理.
