RELATIVE PERTURBATION BOUNDS FOR THE JOINT SPECTRUM OF COMMUTING TUPLES OF MATRICES
Published online by Cambridge University Press: 05 July 2018
Abstract
In this paper, we study the relative perturbation bounds for joint
eigenvalues of commuting tuples of normal $n\times n$ matrices. Some Hoffman–Wielandt-type relative perturbation
bounds are proved using the Clifford algebra technique. We also extend a
result for diagonalisable matrices which improves a relative perturbation
bound for single matrices.
