The book provides a comprehensive introduction to compact finite difference methods for solving boundary value ODEs with high accuracy.

The book provides a comprehensive introduction to compact finite difference methods for solving boundary value ODEs with high accuracy. The corresponding theory is based on exact difference schemes (EDS) from which the implementable truncated difference schemes (TDS) are derived. The TDS are now competitive in terms of efficiency and accuracy with the well-studied numerical algorithms for the solution of initial value ODEs. Moreover, various a posteriori error estimators are presented which can be used in adaptive algorithms as important building blocks. The new class of EDS and TDS treated in this book can be considered as further developments of the results presented in the highly respected books of the Russian mathematician A. A. Samarskii. It is shown that the new Samarskii-like techniques open the horizon for the numerical treatment of more complicated problems.The book contains exercises and the corresponding solutions enabling the use as a course text or for self-study. Researchers and students from numerical methods, engineering and other sciences will find this book provides an accessible and self-contained introduction to numerical methods for solving boundary value ODEs.

Diese Festschrift, publiziert aus Anlass des 65. Geburtstages von Dr. Rolf Griebel, ehrt diesen für seine Leistungen als Generaldirektor der Bayerischen Staatsbibliothek, eine der weltweit bedeutendsten Universal- und Forschungsbibliotheken.

Systeme gewöhnlicher Differentialgleichungen spielen bei der mathematischen Modellierung naturwissenschaftlicher, technischer und ökonomischer Prozesse sowie bei innermathematischen Fragestellungen eine fundamentale Rolle. Dieses zweibändige Lehrbuch vermittelt sowohl für Anfangs- als auch für Randwertprobleme eine Einführung in die Theorie und Praxis moderner numerischer Verfahren, die insbesondere in den heute gängigen Software Paketen zum Einsatz kommen. Im Mittelpunkt des ersten Bandes stehen integrative Techniken zur Lösung von Anfangswertproblemen und linearen Randwertproblemen, während sich der zweite Band mit numerischen Verfahren zur Lösung nichtlinearer Randwertprobleme beschäftigt. Die Darstellung des Stoffes erfolgt in leicht verständlicher und anschaulicher Form. Beispiele dienen als Motivation und Einführung in die Problemstellung. Dieses Buch richtet sich an Studierende der Mathematik sowie mathematisch orientierter Fachrichtungen an Universitäten und Fachhochschulen. Es eignet sich auch als Nachschlagewerk für Mathematiker, Naturwissenschaftler und Ingenieure. Leicht verständliche und anschauliche Einführung in die Thematik Enthält eine Vielzahl von Beispielen Mit MATLAB-Programmen der wichtigsten Schießverfahren Mit frei verfügbarem Zusatzmaterial online Auch im Set mit Band 2: „Nichtlineare Randwertprobleme" erhältlich InhaltAnfangswertproblemeNumerische Analyse von EinschrittverfahrenNumerische Analyse von linearen MehrschrittverfahrenAbsolute Stabilität und SteifheitAllgemeine Lineare Verfahren und Fast-Runge-Kutta VerfahrenZweipunkt-RandwertproblemeNumerische Analyse von Einfach-SchießtechnikenNumerische Analyse von Mehrfach-SchießtechnikenSinguläre Anfangs- und RandwertproblemeGrundlegende Begriffe und Resultate aus der Linearen AlgebraEinige Sätze aus der Theorie der AnfangswertproblemeInterpolation und numerische Integration

This book presents a modern introduction to analytical and numerical techniques for solving ordinary differential equations (ODEs). Contrary to the traditional format—the theorem-and-proof format—the book is focusing on analytical and numerical methods. The book supplies a variety of problems and examples, ranging from the elementary to the advanced level, to introduce and study the mathematics of ODEs. The analytical part of the book deals with solution techniques for scalar first-order and second-order linear ODEs, and systems of linear ODEs—with a special focus on the Laplace transform, operator techniques and power series solutions. In the numerical part, theoretical and practical aspects of Runge-Kutta methods for solving initial-value problems and shooting methods for linear two-point boundary-value problems are considered. The book is intended as a primary text for courses on the theory of ODEs and numerical treatment of ODEs for advanced undergraduate and early graduatestudents. It is assumed that the reader has a basic grasp of elementary calculus, in particular methods of integration, and of numerical analysis. Physicists, chemists, biologists, computer scientists and engineers whose work involves solving ODEs will also find the book useful as a reference work and tool for independent study. The book has been prepared within the framework of a German–Iranian research project on mathematical methods for ODEs, which was started in early 2012.

The book discusses the solutions to nonlinear ordinary differential equations (ODEs) using analytical and numerical approximation methods. Recently, analytical approximation methods have been largely used in solving linear and nonlinear lower-order ODEs. It also discusses using these methods to solve some strong nonlinear ODEs.  There are two chapters devoted to solving nonlinear ODEs using numerical methods, as in practice high-dimensional systems of nonlinear ODEs that cannot be solved by analytical approximate methods are common. Moreover, it studies analytical and numerical techniques for the treatment of parameter-depending ODEs.The book explains various methods for solving nonlinear-oscillator and structural-system problems, including the energy balance method, harmonic balance method, amplitude frequency formulation, variational iteration method, homotopy perturbation method, iteration perturbation method, homotopy analysis method, simple and multiple shooting method, and the nonlinear stabilized march method. This book comprehensively investigates various new analytical and numerical approximation techniques that are used in solving nonlinear-oscillator and structural-system problems. Students often rely on the finite element method to such an extent that on graduation they have little or no knowledge of alternative methods of solving problems. To rectify this, the book introduces several new approximation techniques.
