On becoming familiar with difference equations and their close re lation to differential equations, I was in hopes that the theory of difference equations could be brought completely abreast with that for ordinary differential equations. [HUGH L. TURRITTIN, My Mathematical Expectations, Springer Lecture Notes 312 (page 10), 1973] A major task of mathematics today is to harmonize the continuous and the discrete, to include them in one comprehensive mathematics, and to eliminate obscurity from both. [E. T. BELL, Men of Mathematics, Simon and Schuster, New York (page 13/14), 1937] The theory of time scales, which has recently received a lot of attention, was introduced by Stefan Hilger in his PhD thesis [159] in 1988 (supervised by Bernd Aulbach) in order to unify continuous and discrete analysis. This book is an intro duction to the study of dynamic equations on time scales. Many results concerning differential equations carryover quite easily to corresponding results for difference equations, while other results seem to be completely different in nature from their continuous counterparts. The study of dynamic equations on time scales reveals such discrepancies, and helps avoid proving results twice, once for differential equa tions and once for difference equations. The general idea is to prove a result for a dynamic equation where the domain of the unknown function is a so-called time scale, which is an arbitrary nonempty closed subset of the reals.

Based on a one-year course taught by the author to graduates at the University of Missouri, this book provides a student-friendly account of some of the standard topics encountered in an introductory course of ordinary differential equations. In a second semester, these ideas can be expanded by introducing more advanced concepts and applications. A central theme in the book is the use of Implicit Function Theorem, while the latter sections of the book introduce the basic ideas of perturbation theory as applications of this Theorem. The book also contains material differing from standard treatments, for example, the Fiber Contraction Principle is used to prove the smoothness of functions that are obtained as fixed points of contractions. The ideas introduced in this section can be extended to infinite dimensions.

This is the third book in a series of Across the Life Span volumes that has come from the Biennial Life Span Development Conferences. The authors--well known in their fields--present theoretical and research issues important for the understanding of temperament in infancy and childhood, as well as personality in adolescence and adulthood. Current findings placed within theoretical and historical contexts make each chapter distinctive. The chapter authors focus on their work and its implications for temperament and personality issues across the life span. In addition, they include summaries of research by other investigators and theorists, placing their work and that of others in a lifespan perspective.

This refreshing, introductory textbook covers both standard techniques for solving ordinary differential equations, as well as introducing students to qualitative methods such as phase-plane analysis. The presentation is concise, informal yet rigorous; it can be used either for 1-term or 1-semester courses. Topics such as Euler's method, difference equations, the dynamics of the logistic map, and the Lorenz equations, demonstrate the vitality of the subject, and provide pointers to further study. The author also encourages a graphical approach to the equations and their solutions, and to that end the book is profusely illustrated. The files to produce the figures using MATLAB are all provided in an accompanying website. Numerous worked examples provide motivation for and illustration of key ideas and show how to make the transition from theory to practice. Exercises are also provided to test and extend understanding: solutions for these are available for teachers.

Das vorliegende Buch entstand aus der ausgearbeiteten Mitschrift der Vorlesung "Stabilitätstheorie", die Herr Prof. Parks im Winter semester 1979/80 als Gastprofessor an der Ruhr-Universität in Bochum hielt. Diese Vorlesung wandte sich an Studenten der Regelungstechnik, die über Grundkenntnisse der mathematischen Beschreibung dynamischer Vorgänge mittels Differentialgleichungen verfügten. Obwohl die Sta bilität dynamischer Systeme vom technischen Standpunkt aus darge stellt wird, ist das Buch auch für den Leser von Interesse, der mit dynamischen Prozessen im nichttechnischen Bereich, z. B. der Biokyber netik, der Meteorologie, usw. zu tun hat. Das Buch erfordert - abge sehen von dem Verständnis zur Beschreibung dynamischer Vorgäng- keine besonderen Vorkenntnisse vom Leser und ist als Einführung in das Gebiet gut geeignet. Andererseits wird ein Uberblick über sehr viele Methoden der Stabilitätsprüfung gegeben, so daß es für den jenigen, der sich schnell über eine Methode informieren will, durch aus als "Nachschlagewerk" verwendbar ist. Besonderer Wert wurde da rauf gelegt, nicht nur die Anwendung der einzelnen Methoden, sondern auch ihre Ableitung und ihre Zusammenhänge dazustellen. Insofern ist das Buch eine sinnvolle Ergänzung der bisherigen Lehrbuchliteratur auf dem Gebiet der Stabilität dynamischer Systeme. Ich wünsche dem vorliegenden Buch, daß es vor allem auch in der Praxis Interesse findet und Anlaß zur weiteren Anwendung der vor geschlagenen Verfahren wird. Professor Dr. -Ing. H.

Dynamic tools of analysis and modelling are increasingly used in Economics and Biology and have become more and more sophisticated in recent years, to the point where the general students without training in Dynamic Systems (DS) would be at a loss. No doubt they are referred to the original sources of mathematical theorems used in the various proofs, but the level of mathematics is generally beyond them. Students are thus left with the burden of somehow understanding advanced mathematics by themselves, with· very little help. It is to these general students, equipped only with a modest background of Calculus and Matrix Algebra that this book is dedicated. It aims at providing them with a fairly comprehensive box of dynamical tools they are expected to have at their disposal. The first three Chapters start with the most elementary notions of first and second order Differential and Difference Equations. For these, no matrix theory and hardly any calculus are needed. Then, before embarking on linear and nonlinear DS, a review of some Linear Algebra in Chapter 4 provides the bulk of matrix theory required for the study of later Chapters. Systems of Linear Differ ential Equations (Ch. 5) and Difference Equations (Ch. 6) then follow to provide students with a good background in linear DS, necessary for the subsequent study of nonlinear systems. Linear Algebra, reviewed in Ch. 4, is used freely in these and subsequent chapters to save space and time.

As the author notes in the preface, "The purpose of this book is to acquaint a broad spectrum of students with what is today known as 'abstract algebra.'" Written for a one-semester course, this self-contained text includes numerous examples designed to base the definitions and theorems on experience, to illustrate the theory with concrete examples in familiar contexts, and to give the student extensive computational practice.The first three chapters progress in a relatively leisurely fashion and include abundant detail to make them as comprehensible as possible. Chapter One provides a short course in sets and numbers for students lacking those prerequisites, rendering the book largely self-contained. While Chapters Four and Five are more challenging, they are well within the reach of the serious student.The exercises have been carefully chosen for maximum usefulness. Some are formal and manipulative, illustrating the theory and helping to develop computational skills. Others constitute an integral part of the theory, by asking the student to supply proofs or parts of proofs omitted from the text. Still others stretch mathematical imaginations by calling for both conjectures and proofs.Taken together, text and exercises comprise an excellent introduction to the power and elegance of abstract algebra. Now available in this inexpensive edition, the book is accessible to a wide range of students, who will find it an exceptionally valuable resource.
