This book delineates the various types of factorization problems for matrix and operator functions. The problems originate from, or are motivated by, the theory

The present book deals with canonical factorization of matrix and operator functions that appear in state space form or that can be transformed into such a form

The volume is dedicated to Lev Sakhnovich, who made fundamental contributions in operator theory and related topics. Besides bibliographic material, it includes

The state space method developed in the last decades allows us to study the theory of linear systems by using tools from the theory of linear operators; convers

A collection of 25 papers dedicated to Israel Gohberg, an outstanding leader in operator theory. Also containing a review of his contributions to mathematics an
