On perturbations of matrix pencils with real spectra. II. (English) Zbl 0852.15008

[For part I see the second author, ibid. 62, No. 205, 231-265 (1994; Zbl 0795.15012)]. The principal observation is that using perturbation identities proved in the first part can reduce the problem of finding perturbation bounds for diagonalizable matrix pencils with real spectra to that of finding perturbation bounds for matrices similar to unitary matrices.
