## Differential Equations

Unlike other books in the market, this second edition presents differential equations consistent with the way scientists and engineers use modern methods in their work. Technology is used freely, with more emphasis on modeling, graphical representation, qualitative concepts, and geometric intuition than on theoretical issues. It also refers to larger-scale computations that computer algebra systems and DE solvers make possible. And more exercises and examples involving working with data and devising the model provide scientists and engineers with the tools needed to model complex real-world situations.

## Differentialgleichungen und ihre Anwendungen

Dieses richtungsweisende Lehrbuch für die Anwendung der Mathematik in anderen Wissenschaftszweigen gibt eine Einführung in die Theorie der gewöhnlichen Differentialgleichungen. Fortran und APL-Programme geben den Studenten die Möglichkeit, verschiedene numerische Näherungsverfahren an ihrem PC selbst durchzurechnen. Aus den Besprechungen: "Die Darstellung ist überall mathematisch streng und zudem ungemein anregend. Abgesehen von manchen historischen Bemerkungen ... tragen dazu die vielen mit ausführlichem Hintergrund sehr eingehend entwickelten praktischen Anwendungen bei. ... Besondere Aufmerksamkeit wird der physikalisch und technisch so wichtigen Frage nach Stabilität von Lösungen eines Systems von Differentialgleichungen gewidmet. Das Buch ist wegen seiner geringen Voraussetzungen und vorzüglichen Didaktik schon für alle Studenten des 3. Semesters geeignet; seine eminent praktische Haltung empfiehlt es aber auch für alle Physiker, die mit Differentialgleichungen und ihren Anwendungen umzugehen haben." #Physikalische Blätter#
## Differential Equations an Introduction to Modern Methods and Applications, Brannan & Boyce, 3rd Ed, 2015

P R E F A C E This is a textbook for a first course in differential equations. The book is intended for science and engineering majors who have completed the calculus sequence, but not necessarily a first course in linear algebra. It emphasizes a systems approach to the subject and integrates the use of modern computing technology in the context of contemporary applications from engineering and science. Our goal in writing this text is to provide these students with both an introduction to, and a survey of, modern methods, applications, and theory of differential equations that is likely to serve them well in their chosen field of study. The subject matter is presented in a manner consistent with the way practitioners use differential equations in their work; technology is used freely, with more emphasis on methods, modeling, graphical representation, qualitative concepts, and geometric intuition than on theory. Notable Changes in the Third Edition This edition is a substantial revision of the second edition. The most significant changes are: ▶ Enhanced Page Layout We have placed important results, theorems, definitions, and tables in highlighted boxes and have put subheadings just before the most important topics in each section. This should enhance readability for both students and instructors and help students to review material for exams. ▶ Increased Emphasis on Qualitative Methods Qualitative methods are introduced early. Throughout the text, new examples and problems have been added that require the student to use qualitative methods to analyze solution behavior and dependence of solutions on parameters. ▶ New Chapter on Numerical Methods Discussions on numerical methods, dispersed over three chapters in the second edition, have been revised and reassembled as a unit in Chapter 8. However, the first three sections of Chapter 8 can be studied by students after they have studied Chapter 1 and the first two sections of Chapter 2. ▶ Chapter 1: Introduction This chapter has been reduced to three sections. In Section 1.1 we follow up on introductory models and concepts with a discussion of the art and craft of mathematical modeling. Section 1.2 has been replaced by an early introduction to qualitative methods, in particular, phase lines and direction fields. Linearization and stability properties of equilibrium solutions are also discussed. In Section 1.3 we cover definitions, classification, and terminology to help give the student an organizational overview of the subject of differential equations. ▶ Chapter 2: First Order Differential Equations New mathematical modeling problems have been added to Section 2.3, and a new Section 2.7 on subsitution methods has been added. Sections on numerical methods have been moved to Chapter 8. ▶ Chapter 3: Systems of Two First Order Equations The discussion of Wronskians and fundamental sets of solutions has been supplemented with the definition of, and relationship to, linearly independent solutions of two-dimensional linear systems. ▶ Chapter 4: Second Order Linear Equations Section 4.6 on forced vibrations, frequency response, and resonance has been rewritten to improve its readability for students and instructors. v vi Preface ▶ Chapter 10: Orthogonal Functions, Fourier Series and Boundary-Value Problems This chapter gives a unified treatment of classical and generalized Fourier series in the framework of orthogonal families in the space PC[a, b]. ▶ Chapter 11: Elementary Partial Differential Equations Material and projects on the heat equation, wave equation, and Laplace’s equation that appeared in Chapters 9 and 10 of the second edition, have been moved to Chapter 11 in the third edition. ▶ Miscellaneous Changes and Additions Changes have been made in current problems, and new problems have been added to many of the section problem sets. For ease in assigning homework, boldface headings have been added to partition the problems into groups corresponding to major topics discussed in the section. Major Features ▶ Flexible Organization. Chapters are arranged, and sections and projects are structured, to facilitate choosing from a variety of possible course configurations depending on desired course goals, topics, and depth of coverage. ▶ Numerous and Varied Problems. Throughout the text, section exercises of varying levels of difficulty give students hands-on experience in modeling, analysis, and computer experimentation. ▶ Emphasis on Systems. Systems of first order equations, a central and unifying theme of the text, are introduced early, in Chapter 3, and are used frequently thereafter. ▶ Linear Algebra and Matrix Methods. Two-dimensional linear algebra sufficient for the study of two first order equations, taken up in Chapter 3, is presented in Section 3.1. Linear algebra and matrix methods required for the study of linear systems of dimension n (Chapter 6) are treated in Appendix A. ▶ Optional Computing Exercises. In most cases, problems requesting computergenerated solutions and graphics are optional. ▶ Visual Elements. The text contains a large number of illustrations and graphs. In addition, many of the problems ask the student to compute and plot solutions of differential equations. ▶ Contemporary Project Applications. Optional projects at the end of all but one of Chapters 2 through 11 integrate subject matter in the context of exciting, often contemporary, applications in science and engineering. ▶ Laplace Transforms. A detailed chapter on Laplace transforms discusses systems, discontinuous and impulsive input functions, transfer functions, feedback control systems, poles, and stability. ▶ Control Theory. Ideas and methods from the important application area of control theory are introduced in some examples, some projects, and in the last section on Laplace transforms. All this material is optional. ▶ Recurring Themes and Applications. Important themes, methods, and applications, such as dynamical system formulation, phase portraits, linearization, stability of equilibrium solutions, vibrating systems, and frequency response, are revisited and reexamined in a variety of mathematical models under different mathematical settings. ▶ Chapter Summaries. A summary at the end of each chapter provides students and instructors with a bird’s-eye view of the most important ideas in the chapter. ▶ Answers to Problems. Answers to selected odd-numbered problems are provided at the end of the book; many of them are accompanied by a figure. Problems that require the use of a computer are marked with . Whilewe feel that students will benefit from using the computer on those problems where numerical approximations Preface vii or computer-generated graphics are requested, in most problems it is clear that use of a computer, or even a graphing calculator, is optional. Furthermore there are a large number of problems that do not require the use of a computer. Thus the book can easily be used in a course without using any technology. Relation of This Text to Boyce and DiPrima Brannan and Boyce is an offshoot of thewell-known textbook by Boyce and DiPrima. Readers familiar with Boyce and DiPrima will doubtless recognize in the present book some of the hallmark features that distinguish that textbook. To help avoid confusion among potential users of either text, the primary differences are described below: ▶ Brannan and Boyce is more sharply focused on the needs of students of engineering and science, whereas Boyce and DiPrima targets a somewhat more general audience, including engineers and scientists. ▶ Brannan and Boyce is intended to be more consistent with the way contemporary scientists and engineers actually use differential equations in the workplace. ▶ Brannan and Boyce emphasizes systems of first order equations, introducing them earlier, and also examining them in more detail than Boyce and DiPrima. Brannan and Boyce has an extensive appendix on matrix algebra to support the treatment of systems in n dimensions. ▶ Brannan and Boyce integrates the use of computers more thoroughly than Boyce and DiPrima, and assumes that most students will use computers to generate approximate solutions and graphs throughout the book. ▶ Brannan and Boyce emphasizes contemporary applications to a greater extent than Boyce and DiPrima, primarily through end-of-chapter projects. ▶ Brannan and Boyce makes somewhat more use of graphs, with more emphasis on phase plane displays, and uses engineering language (e.g., state variables, transfer functions, gain functions, and poles) to a greater extent than Boyce and DiPrima. Options for Course Structure Chapter dependencies are shown in the following block diagram: Chapter 3 Systems of Two First Order Equations Chapter 2 First Order Differential Equations Chapter 6 Systems of First Order Linear Equations Chapter 7 Nonlinear Differential Equations and Stability Chapter 4 Second Order Linear Equations Chapter 5 The Laplace Transform Chapter 9 Series Solutions of Second Order Equations Chapter 10 Orthogonal Functions, Fourier Series, and BVPs Chapter 8 Numerical Methods Chapter 11 Elementary PDEs Appendix A Matrix Algebra Chapter 1 Introduction viii Preface The book has much built-in flexibility and allows instructors to choose from many options. Depending on the course goals of the instructor and background of the students, selected sections may be covered lightly or even omitted. ▶ Chapters 5, 6, and 7 are independent of each other, and Chapters 6 and 7 are also independent of Chapter 4. It is possible to spend much class time on one of these chapters, or class time can be spread over two or more of them. ▶ The amount of time devoted to projects is entirely up to the instructor. ▶ For an honors class, a class consisting of students who have already had a course in linear algebra, or a course in which linear algebra is to be emphasized, Chapter 6 may be taken up immediately following Chapter 2. In this case, material from Appendix A, as well as sections, examples, and problems from Chapters 3 and 4, may be selected as needed or desired. This offers the possibility of spending more class time on Chapters 5, 7, and/or selected projects.

## Scientific Computing and Differential Equations

Scientific Computing and Differential Equations: An Introduction to Numerical Methods, is an excellent complement to Introduction to Numerical Methods by Ortega and Poole. The book emphasizes the importance of solving differential equations on a computer, which comprises a large part of what has come to be called scientific computing. It reviews modern scientific computing, outlines its applications, and places the subject in a larger context. This book is appropriate for upper undergraduate courses in mathematics, electrical engineering, and computer science; it is also well-suited to serve as a textbook for numerical differential equations courses at the graduate level. An introductory chapter gives an overview of scientific computing, indicating its important role in solving differential equations, and placing the subject in the larger environment Contains an introduction to numerical methods for both ordinary and partial differential equations Concentrates on ordinary differential equations, especially boundary-value problems Contains most of the main topics for a first course in numerical methods, and can serve as a text for this course Uses material for junior/senior level undergraduate courses in math and computer science plus material for numerical differential equations courses for engineering/science students at the graduate level
## Differential Equations

This book presents, in a unitary frame and from a new perspective, the main concepts and results of one of the most fascinating branches of modern mathematics, namely differential equations, and offers the reader another point of view concerning a possible way to approach the problems of existence, uniqueness, approximation, and continuation of the solutions to a Cauchy problem. In addition, it contains simple introductions to some topics which are not usually included in classical textbooks: the exponential formula, conservation laws, generalized solutions, Caratheodory solutions, differential inclusions, variational inequalities, viability, invariance, and gradient systems. In this new edition, some typos have been corrected and two new topics have been added: Delay differential equations and differential equations subjected to nonlocal initial conditions. The bibliography has also been updated and expanded.
## Partielle Differentialgleichungen

Dieses Buch ist eine umfassende Einführung in die klassischen Lösungsmethoden partieller Differentialgleichungen. Es wendet sich an Leser mit Kenntnissen aus einem viersemestrigen Grundstudium der Mathematik (und Physik) und legt seinen Schwerpunkt auf die explizite Darstellung der Lösungen. Es ist deshalb besonders auch für Anwender (Physiker, Ingenieure) sowie für Nichtspezialisten, die die Methoden der mathematischen Physik kennenlernen wollen, interessant. Durch die große Anzahl von Beispielen und Übungsaufgaben eignet es sich gut zum Gebrauch neben Vorlesungen sowie zum Selbststudium.
