From the reviews: "[β¦] An excellent textbook in the theory of linear operators in Banach and Hilbert spaces. It is a thoroughly worthwhile reference work both for graduate students in functional analysis as well as for researchers in perturbation, spectral, and scattering theory. [β¦] I can recommend it for any mathematician or physicist interested in this field." Zentralblatt MATH

This text, part of the "Springer Classics of Mathematics" series, examines perturbation theory for linear operators.
<p>In view of recent development in perturbation theory, supplementary notes and a supplementary bibliography are added at the end of the new edition. Little change has been made in the text except that the paraΒ graphs V-Β§ 4.5, VI-Β§ 4.3, and VIII-Β§ 1.4 have been completely rewritten, and a number o
