PERTURBATION OF EIGENVALUES FOR PERIODIC MATRIX PAIRS VIA JOINT SPECTRUM
Eric King‐wah Chu, A. J. Pryde · Taiwanese Journal of Mathematics · 2008
We shall link the well-established concept of joint spectrum with the interesting and practical periodic eigenvalue problems (PEVPs). A Bauer- Fike perturbation theory, incorporating a Clifford algebra technique, for joint spectrum is applied to PEVPs, producing new perturbation results.
