PERTURBATION BOUNDS FOR SUBSPACES ASSOCIATED WITH PERIODIC EIGENPROBLEMS
Jiguang Sun · Taiwanese Journal of Mathematics · 2005
The concept of periodic deflating subspaces of regular periodic matrix pairs $\{(A_j, B_j)\}_{j=1}^K$ is a generalization of deflating subspaces of a regular matrix pair $(A,B)$. In this paper we derive perturbation bounds for each individual subspace of simple periodic deflating subspaces.
