Traces and Determinants of Linear Operators

3-7643-6177-8 * 2000 * Hardcover * 272 pages

This book is dedicated to a theory of traces and determinants on embedded algebras of linear operators, where the trace and determinant are extended from finite rank operators by a limit process. All the important classical examples of traces and determinants suggested by Hill, von Koch, Fredholm, Poincaré, Ruston and Grothendieck are exhibited. In particular, the determinants which were first introduced by Hill and Poincaré in their investigations of infinite systems of linear equations stemming from problems in celestial mechanics are studied. Most of Fredholm's seminal results are presented in this book by the editors' own means. Formulas for traces and determinants in a Hilbert space setting are readily derived, again. Also investigated are
generalizations to Banach spaces. Furthermore, a large part of this book is devoted to generalizations of the regularized determinants introduced by Hilbert and Carleman, and regularized determinants of higher order in embedded algebras are introduced. Much attention is paid to integral operators with semi-separable kernels, and explicit formulas of traces and determinants are given.

One of the conclusions of this book (based on results of Ben-Artziand Perelson) is that the trace and determinant, which are considered here, essentially depend not only on the operator but also on the algebra containing this operator. In fact, it turns out that by considering the same operator in different algebras, the trace and determinant of non nuclear operators can be almost any complex number. However, an operator is invertible if and only if each determinant is different from zero. Also each of the determinants can be used in the inversion formula.

An attractive feature of this book is that it contains the charming classical theory of determinants together with its most recent concrete andabstract developments and applications. The general presentation of thebook is based on the editors' work. The material is self-contained and may be used for advanced courses and seminars.

Toeplitz Matrices, Asymptotic Linear Algebra, and Functional Analysis

3-7643-6290-1 * 2000 * Softcover * 104 pages

This text is a self-contained introduction to some problems for Toeplitz matrices that are placed in the borderland between linear algebra and functional analysis. The text looks at Toeplitz matrices with rational symbols, and focuses attention on the asymptotic behavior of the singular values, which includes the behavior of the norms, the norms of the inverses, and the condition numbers as special cases.
The text illustrates that the asymptotics of
several linear algebra characteristics depend in a fascinating way on functional analytic properties of infinite matrices. Many convergence results can very comfortably be obtained by working with appropriate C*-algebras, while refinements of these results, for example, estimates of the convergence speed, nevertheless require hard analysis.

The book presents a course given by the author in New Delhi in January 2000. It is a self-contained introduction to some problems for Toeplitz matrices. The text illustrates that the asymptotics of several linear algebra characteristics depend in a fascinating way on functional analytic properties of
infinite matrices.

Controversy and Consensus
Nuclear Beta Decay 1911-1934 Carsten Jensen (1948-1990)

3-7643-5313-9 * 2000 * Hardcover * 240 pages * 52 Illustrations

The book describes in detail the considerable efforts by theoretical and experimental physicists to understand the beta spectra of atomic nuclei. After a brief prehistory, the main narrative spans the period from 1911, when Rutherford and his collaborators in Manchester established that the atom had an extremely massive nucleus, until 1934, when the question of beta decay was settled theoretically by Fermi and others. The book discusses extensively the intense controversy over several years between Lise Meitner in Germany and C.D. Ellis in England about the origin of beta rays. Aside from providing a rich story in its own right, the narrative is uniquely suited to illuminate currently debated issues such as the relationship between theory and experiment, scientific controversy, the role and resolution of anomalies, and national differences in the approach to science.

Optimal Control

0-8176-4075-4 * 2000 * Hardcover * 365 pages

Optimal control emerged as a distinct field of research only in recent decades. It provides a unified perspective of optimization problems, arising in scheduling and the control of engineering devices, that are beyond the reach of traditional analytical and computational techniques. In addition, the field has contributed significant advances to branches of applied mathematics and broad applications in process control, scheduling, robotics, resource economics, and other areas.

Optimal Control brings together many of the important advances in 'nonsmooth' optimal control over the last two decades concerning necessary conditions, minimizer regularity and global optimality conditions associated with the Hamilton-Jacobi equation. The book's development and analysis is largely self-contained and incorporates many simplifications and unifying features for subject.

Features and Topics:

A comprehensive overview is provided for specialists and non-specialists Authoritative, coherent and accessible coverage of the role of nonsmooth analysis in investigating minimizing curves for optimization
Chapter coverage of dynamic programming from a system-theoretic viewpoint Thorough coverage of necessary conditions, including nonsmooth maximum principles and versions of the Euler Lagrange condition for differential inclusion problems Accessible treatment of topics, such as minimizer regularity and free end-time necessary conditions for problems with data discontinuous in time

This new book is an essential resource for an authoritative and comprehensive presentation of the foundations and application of nonsmooth optimal control. Postgraduates, researchers and professionals in systems, control, optimization and applied mathematics will find that the book is accessible, provides a rich source of insights and offers clear exposition.
