一类Jacobi矩阵逆特征值问题的扰动分析

The Perturbation Aanalysis about an Inverse Eigenvalue of a Jacobi Matrix

利用Jacobi矩阵特征值表示特征向量的方法对于一类Jacobi矩阵逆特征值问题给出了新的扰动上界,这些结果改进和推广了已有的相关结论,对于进一步研究此类问题提供了可靠的理论依据.

Using methods of eigenvalue of Jacobi matrixes expressing eigenvector,We discuss a kind of Jacobi matrixes inverse eigenvalue problem and give new perturbation supremum.It improves and extends former relating conclusion,and provides reliably theoretical base for further studying this problem.
