Reforming Estimation of the Perturbation Bound in Wilkinson Theorem

摘要:

Wilkinson定理是代数特征值问题中的一个经典定理,文章给出了 Wilkinson定理的结果中关于扰动矩阵上界的另一种估计形式,并指出该形式对 Wilkinson定理具有一定的改进。

Abstract:

Wilkinson theorem is a classical theorem in the problem of algebraic eigenvalue . In this paper, a new form of es.timation of the perturbation bound in Wilkinson theorem was given, and that it was a reforming result was proved.
