Reihe: Operator Theory: Advances and Applications

The present book is a memorial volume devoted to Peter Jonas. It contains a collection of recent original research papers written by well-known specialists in the field of operator theory in Hilbert and Krein spaces. The papers contain new results for problems close to the area of research of Peter Jonas: Spectral, perturbation and scattering theory for linear operators and the analysis of related classes of functions.
