Motivation The latest texts on linear systems for engineering students have begun incorpo- rating chapters on robust control using the state space approach to HOC control for linear finite dimensional time-invariant systems. While the pedagogical and computational advantages of this approach are not to be underestimated, there are, in my opinion, some disadvantages. Among these disadvantages is the narrow viewpoint that arises from the amputation of the finite dimensional time-invariant case from the much more general theory that had been developed using frequency domain methods.

This volume presents the Proceedings of the joint US/Israel Workshop on Operator Theory and its Applications, held in February 1992 at the Ben Gurion University of the Negev. The volume contains a selection of papers covering a wide range of topics in modern operator theory and its applications, from abstract operator theory, to system theory and computers in operator models. The papers treat linear and nonlinear problems, and study operators from different abstract and concrete classes. It is suitable for both pure and applied mathematicians, and engineers.
