    This book is devoted to the ubiquity of the Schur parameters. A dilation theoretic view leads to a unified perspective on several topics where Schur parameters appear as basic cells. Together with the transmission line, their physical counterpart, they appear in scattering theory, in modeling, prediction and filtering of nonstationary processes, in signal processing, geophysics and system theory.

    Decompositions and models for Hilbert-space operators have been active research topics in recent years, and this book is intended as an introduction to this area of operator theory. One approach to multivariate operator theory involves concepts and techniques from algebraic and complex geometry and is formulated in terms of Hilbert modules. In these notes we provide an introduction to this approach including many proofs.

Orthogonal decompositions of the operators D and T themselves are considered in Section 3, where it is investigated on which subspaces of H these operators still act as bilateral shifts; in particular, as bilateral.

Decompositions and models for Hilbert-space operators have been very active research topics in operator theory over the past three decades.

The main motivation behind them is the in­ variant subspace problem: does every Hilbert-space operator. This book is intended as an introduction to this crucial part of operator theory, providing for the student a unified access, from an abstract point of view, to an active research field.

It focuses on decompositions and models as if they were the main characters in a plot, chosen from a myriad of equally important characters, and highlighted for their illustrative attributes.

[Carlos S Kubrusly] -- By a Hilbert-space operator we mean a bounded linear transformation be tween separable complex Hilbert spaces.

Decompositions and models for Hilbert-space operators have been very active research. The search for nontrivial invariant subspaces has undoubtly yielded a lot of nice results in operator theory, among them, those concerning decompositions and models for Hilbert-space operators.

This book contains nine chapters. The study of model spaces, the closed invariant subspaces of the backward shift operator, is a vast area of research with connections to complex analysis, operator theory and functional analysis.

This self-contained text is the ideal introduction for newcomers to the field. Abstract. An operator is said to be a universal model if every operator in B[H] is similar to a multiple of a part of it.

Drop “universal” by constraining the definition to a class of operators: an operator is a model for a class of operators in B[H] if every operator in that class is similar to a multiple of a part of it. Equivalently (see Proposition ), if every operator in that class.
