Spectral Theory of Schrodinger Operators

Expected publication date is February 26, 2004

Description

This volume gathers the articles based on a series of lectures from a workshop held at the Institute of Applied Mathematics of the National University of Mexico. The aim of the book is to present to a non-specialized audience the basic tools needed to understand and appreciate new trends of research on Schrodinger operator theory.

Topics discussed include various aspects of the spectral theory of differential operators, the theory of self-adjoint operators, finite rank perturbations, spectral properties of random Schrodinger operators, and scattering theory for Schrodinger operators.

The material is suitable for graduate students and research mathematicians interested in differential operators, in particular, spectral theory of Schrodinger operators.

Topology of Closed One-Forms

Expected publication date is March 21, 2004

Description

Viewed locally, a closed one-form on a manifold is a smooth function up to an additive constant. The global structure of a closed one-form is mainly determined by its de Rham cohomology class. In this book, Michael Farber studies fascinating geometrical, topological, and dynamical properties of closed one-forms. In particular, he reveals the relations between their global and local features.

In 1981, S. P. Novikov initiated a generalization of Morse theory in which, instead of critical points of smooth functions, one deals with closed one-forms and their zeros. The first two chapters of the book, written in textbook style, give a detailed exposition of Novikov theory, which now plays a fundamental role in geometry and topology.

In the following chapters the author describes the universal chain complex that lives over a localization (in the sense of P. M. Cohn) of the group ring and relates the topology of the underlying manifold with information about zeros of closed one-forms. Using this complex, many different variations and generalizations of the Novikov inequalities are obtained, including Bott-type inequalities for closed one-forms, equivariant inequalities, and inequalities involving von Neumann Betti numbers. Another significant result in the book is a solution of the problem about exactness of the Novikov inequalities for manifolds with the infinite cyclic fundamental group.

One of the chapters deals with the problem raised by E. Calabi about intrinsically harmonic closed one-forms and their Morse numbers. Presented are the solution of this problem and a detailed study of topological properties of singular foliations of closed one-forms.

The last chapter suggests a completely new Lusternik-Schnirelman-type theory for dynamical systems. Closed 1-forms appear in dynamics through the concept of a Lyapunov 1-form of a flow. As is shown in the book, homotopy theory may be used to predict the existence of homoclinic orbits and homoclinic cycles in dynamical systems ("focusing effect").

The book is suitable for graduate students and researchers interested in geometry and topology.

Mathematical Models of Hysteresis and their Applications
Second Edition

Description

This new edition has been significantly revised and updated to reflect advances in the field since the publication of the first edition, such as the systematic experimental testing of Preisach models of hysteresis. The author has, however, retained the two most salient features of the original, the emphasis on the universal nature of mathematical models of hysteresis and their applicability to the description of hysteresis phenomena in various areas of science, technology and economics and its accessibility to a broad audience of researchers, engineers, and students.

Contents

The classical Preisach model of hysteresis, Generalized scalar Preisach models of hysteresis, Vector Preisach models of hysteresis, Stochastic aspects of hysteresis, Superconducting hysteresis, Eddy current hysteresis. Core losses.

Differential Equations with Mathematica
Third Edition

Reviews

Stephen McDowall of Western Washington University says:
" The topics covered are extensive. The order and organization are good, especially in terms of
increasing sophistication of the mathematics involved and in the complexity of the Mathematica
programming necessary"
March 2003
Mark Lusk of The Colorado School of Mines says:
" I am considering the adoption of this book for my graduate class in Simulation and Modeling. I
make very heavy use of Mathematica and have a weekly computer lab. I am tempted to make this
the sole, required text for that course"
March 2003

Description

The Third Edition of the Differential Equations with Mathematica integrates new applications from a variety of fields,especially biology, physics, and engineering. The new handbook is also completely compatible with Mathematica version 5.0 and is a perfect introduction for Mathematica beginners. The book/CD-ROM package contains built-in commands that lets the user solve problems directly using graphical solutions.
