Discreteness and Continuity in Problems of Chaotic Dynamics

Michael Blank

This book presents the study of ergodic properties of so-called chaotic dynamical systems. One of the central topics is the interplay between deterministic and quasi-stochastic behaviour in chaotic dynamics and between properties of continuous dynamical systems and those of their discrete approximations. Using simple examples, the author describes the main phenomena known in chaotic dynamical systems, studying topics such as the operator approach in chaotic dynamics, stochastic stability, and the so-called coupled systems. The last two chapters are devoted to problems of numerical modelling of chaotic dynamics.

Contents: Introduction; Operator approach in chaotic dynamics; Random perturbations of dynamical systems; Weakly coupled dynamical systems; Phase space discretisation in dynamical systems; Ergodic properties of some methods for numerical modelling of chaotic dynamics; Bibliography; Index.

Harmonic Analysis and Nonlinear Differential Equations

M.L. Lapidus, L.H. Harper and A.J. Rumbos

This volume is a collection of papers dealing with harmonic analysis and nonlinear differential equations and stems from a conference on these two areas and their interface held in November 1995 at the University of California, Riverside, in honour of V.L. Shapiro. There are four papers dealing directly with the use of harmonic analysis techniques to solve challenging problems in nonlinear partial differential equations. There are also several survey articles on recent developments in multiple trigonometric series, dyadic harmonic analysis, special functions, analysis on fractals, and shock waves, as well as papers with new results in nonlinear differential equations. These survey articles, along with several of the research articles, cover a wide variety of applications such as turbulence, general relativity and black holes, neural networks, and diffusion and wave propagation in porous media. A number of the papers contain open problems in their respective areas.

This text will also be of interest to those working in differential equations.

Linear and Nonlinear Perturbations of the Operator div

V.G. Osmolovskii

The perturbation theory for the operator div is of particular interest in the study of boundary-value problems for the general nonlinear equation F(\dot{y},y,x)=0. Taking as the linearisation the first order operator Lu = Cijuixj +Ciui, one can under certain conditions regard the operator L as a compact perturbation of the operator div.

This book presents results on boundary-value problems for L and the theory of nonlinear perturbations of L. Specifically, necessary and sufficient solvability conditions in explicit form are found for various boundary-value problems for the operator L. An analog of the Weyl decomposition is proved.

Mathematics of Fractals

M. Yamaguti, M. Hata, and J. Kigami

This book aims at providing a handy explanation of the notions behind the self-similar sets called "fractals" and "chaotic dynamical systems". The authors emphasise the beautiful relationship between fractal functions (such as Weierstrass's) and chaotic dynamical systems; these nowhere-differentiable functions are generating functions of chaotic dynamical systems. These functions are shown to be in a sense unique solutions of certain boundary problems. The last chapter of the book treats harmonic functions on fractal sets.

Contents: The fundamentals of fractals; Self-similar sets; An alternative computation for differentiation; In quest of fractal analysis; Recommended reading; Index.

Classical Nonintegrability, Quantum Chaos

A. Knauf and Y.G. Sinai

The lectures, given at the DMV Seminar "Classical Nonintegrability, Quantum Chaos", provide an introduction to the ideas and mathematical techniques of classical and quantum nonlinear dynamics. The chapters on irregular scattering and expanding maps illustrate techniques in nonlinear dynamics using the simplest nontrivial examples. The chapters on quantum chaos and Liouville surfaces stress a phase space geometry approach to semi-classical quantum theory. These lectures can serve as a basis for graduate seminars in mathematics and physics.

Laws of Chaos: Invariant Measures and Dynamical Systems in One Dimension

A. Boyarsky and P. Gora

This book deals with the probabilistic concepts used in the analysis of one-dimensional chaotic systems. The precise description of chaotic behaviour requires the notion of a measure on the phase space. Since this measure describes asymptotic behaviour, it is time invariant, and hence is called invariant. The authors examine those invariant measures which occur in practice, namely the ones which are absolutely continuous with respect to Lebesgue measure, and thus have a probability density function. Important applications are given, ranging from biology to the design of drills.

Variational Methods for Potential Operator Equations

With Applications to Nonlinear Elliptic Equations

Jan Chabrowski

In recent years, there has been a great deal of interest in variational problems for nonlinear elliptic equations characterised by lack of compactness. This book provides a detailed and extensive review of the methods, constrained minimisation, min-max theory of critical points and concentration-compactness principles, that have been developed to deal with these problems. The techniques discussed go far beyond elliptic equations and can be applied to Hamiltonian systems, nonlinear wave equations, and problems related to surfaces of prescribed mean curvature.

One of the most effective theorems applied in many variational problems is the Ambrosetti-Rabinowitz mountain pass theorem, the original proof of which is based on a deformation lemma. The author is concerned with generalisations of this theorem and also presents a different proof based on Ekeland's variational principle combined with techniques from the Clarke theory of generalised gradient. Moreover, on the basis of P.L. Lion's first and second concentration-compactness principle, he presents a novel and simplified approach to concentration-compactness principles, giving rise to the concentration-compactness principle at infinity in both the subcritical and critical case.

The material covered by this book requires some knowledge of functional analysis, nonlinear partial differential equations, and the theory of Sobolev spaces. For the reader's convenience, most of the prerequisites are given in an appendix.

Analysis of Observed Chaotic Data.

H.D.I. Abarbanel

Clearly and systematically develops the analysis of time series of data, both regular and chaotic, for nonlinear systems. The book emphases modern mathematical tools and leads readers from the measurements of one or more variables through building models of the source as a dynamical system, classifying the source by its dynamical characteristics, and predicting and controlling the system. The text not only examines methods for separating the signal from unwanted noise, and for investigating the phase space of the chaotic signal and its properties, but also develops a tool kit for analysing signals from nonlinear sources.

Invariant Manifolds and Fibrations for Perturbed Nonlinear Schrödinger Equations

Charles Yanguang Li and Stephen Wiggins

The nonlinear Schrödinger (NLS) equation is a fundamental nonlinear partial differential equation (PDE) that arises in many areas and engineering, e.g. in plasma physics, nonlinear waves, and nonlinear optics. It is an example of a completely integrable PDE where phase space structure is known in some detail. In this monograph the authors present detailed and pedagogic proofs of persistence theorems for normally hyperbolic invariant manifolds and their stable and unstable manifolds for classes of perturbations of the NLS equations. The authors' techniques are based on an infinite dimensional generalisation of the graph transform and can be viewed as an infinite dimensional generalisation of Feinchel's results. This book also shows that the authors' techniques are quite general and can be applied to a broad class of infinite dimensional dynamical systems.
