Nonlocal Perturbation Analysis of the Schur System of a Matrix
Μ.Μ. Konstantinov, Petko H. Petkov, Nicolai D. Christov · SIAM Journal on Matrix Analysis and Applications · 1994
The sensitivity of the Schur system (the Schur basis and the Schur form) of a general matrix relative to perturbations, is studied. The estimates obtained are nonlocal and sharp. Asymptotic bounds (condition numbers particularly) in the form of power series are derived as a particular case.
