Algebraic Multiplicity of Eigenvalues of Linear Operators

Series: Operator Theory: Advances and Applications , Vol. 177
2007, Approx. 350 p., Hardcover
ISBN: 978-3-7643-8400-5

About this book

This book brings together all available results about the theory of algebraic multiplicities, from the most classic results, like the Jordan Theorem, to the most recent developments, like the uniqueness theorem and the construction of the multiplicity for non-analytic families. Part I (first three chapters) is a classic course on finite-dimensional spectral theory, Part II (the next eight chapters) presents the most general results available about the existence and uniqueness of algebraic multiplicities for real non-analytic operator matrices and families, and Part III (last chapter) transfers these results from linear to nonlinear analysis. The text is as self-contained as possible and suitable for students at the advanced undergraduate or beginning graduate level.

Written for:

Advanced undergraduate and graduate students; researchers in mathematics, mathematical physics and physics

Multiscale Modeling
A Bayesian Perspective

Series: Springer Series in Statistics
2007, XII, 264 p., Hardcover
ISBN: 978-0-387-70897-3

About this book

A wide variety of processes occur on multiple scales, either naturally or as a consequence of measurement. This book contains methodology for the analysis of data that arise from such multiscale processes. The book brings together a number of recent developments and makes them accessible to a wider audience. Taking a Bayesian approach allows for full accounting of uncertainty, and also addresses the delicate issue of uncertainty at multiple scales. The Bayesian approach also facilitates the use of knowledge from prior experience or data, and these methods can handle different amounts of prior knowledge at different scales, as often occurs in practice.

The book is aimed at statisticians, applied mathematicians, and engineers working on problems dealing with multiscale processes in time and/or space, such as in engineering, finance, and environmetrics. The book will also be of interest to those working on multiscale computation research. The main prerequisites are knowledge of Bayesian statistics and basic Markov chain Monte Carlo methods. A number of real-world examples are thoroughly analyzed in order to demonstrate the methods and to assist the readers in applying these methods to their own work. To further assist readers, the authors are making source code (for R) available for many of the basic methods discussed herein.

Due: September 2007

"The text is geared to the needs of the beginning graduate student, covering with complete, well-written proofs the usual major branches of groups, rings, fields, and modules...[n]one of the material one expects in a book like this is missing, and the level of detail is appropriate for its intended audience."

- Alberto Delgado, MathSciNet

"This text promotes the conceptual understanding of algebra as a whole, and that with great methodological mastery. Although the presentation is predominantly abstract...it nevertheless features a careful selection of important examples, together with a remarkably detailed and strategically skillful elaboration of the more sophisticated, abstract theories."

- Werner Kleinert, Zentralblatt

For the new edition, the author has completely rewritten the text, reorganized many of the sections, and even cut or shortened material which is no longer essential. He has added a chapter on Ext and Tor, as well as a bit of topology.

Singularly Perturbed Boundary-Value Problems

Series: International Series of Numerical Mathematics , Vol. 156
2007, Approx. 300 p., Hardcover
ISBN: 978-3-7643-8330-5
A Birkhauser book

About this book

This book offers a detailed asymptotic analysis of some important classes of singularly perturbed boundary value problems which are mathematical models for various phenomena in biology, chemistry, and engineering.

The authors are particularly interested in nonlinear problems, which have hardly been examined so far in the literature dedicated to singular perturbations. This book proposes to fill in this gap, since most applications are described by nonlinear models. Their asymptotic analysis is very interesting, but requires special methods and tools. The treatment presented in this volume combines some of the most successful results from different parts of mathematics, including functional analysis, singular perturbation theory, partial differential equations, and evolution equations. Thus a complete justification for the replacement of various perturbed models with corresponding reduced models, which are simpler but in general have a different character, is offered to the reader

Specific applications are addressed, such as propagation of electromagnetic or mechanical waves, fluid flows, or diffusion processes. However, the methods presented are also applicable to other mathematical models.

The book covers mostly original results by the authors. It is designed for researchers and graduate students.

Explorations in Harmonic Analysis
with Applications to Complex Function Theory and the Heisenberg Group

2008, Approx. 350 p., Hardcover
ISBN: 978-0-8176-4668-4

About this textbook

This text on modern harmonic analysis provides an introduction to the subject in the context in which it is actually applied, in particular, through complex function theory and partial differential equations. The exposition begins with the fundamentals of Fourier analysis, complex function theory, and integral operators and further introduces students to cutting-edge ideas about the Heisenberg group.

The subject is introduced through Fourier series and Hilbert transforms, passing into singular integrals, Riesz fractional integrals and the Calderon-Zygmund singular integrals. Function theory of several complex variables is presented as a prelude to the generalized Cayley transform and the Sigel upper halfspace. Finally, the structure of the Heisenberg group, which naturally models the structures of canonical operators of several complex variables, is explored.

This self-contained text serves as an introduction to analysis on the Heisenberg group. It is an ideal text for advanced undergraduate and graduate students and will aid them in forging new paths of research.
