摘要
讨论一类Hermitian广义特征值问题A-λB,其中A和B是Hermitian矩阵,并且B的(1,1)块和(2,2)块是正定的.考虑当A和B发生Hermitian扰动时相应特征值的界如何变化.数值例子也说明了这些结果.
A class of Hermitian generalized eigenvalue problems A - AB are con- sidered in this paper. Both A and B are Hermitian with (1,1) and (2,2) blocks of B being positive definite. Bounds on how their eigenvalues vary when A and B are perturbed by Hermitian matrices are established. Numerical examples also illustrate these results.
