Wolfgang L. Wendland Libri

This book is devoted to the mathematical foundation of boundary integral equations. The combination of ? nite element analysis on the boundary with these equations has led to very e? cient computational tools, the boundary element methods (see e. g., the authors [139] and Schanz and Steinbach (eds.) [267]). Although we do not deal with the boundary element discretizations in this book, the material presented here gives the mathematical foundation of these methods. In order to avoid over generalization we have con? ned ourselves to the treatment of elliptic boundary value problems. The central idea of eliminating the ? eld equations in the domain and - ducing boundary value problems to equivalent equations only on the bou- ary requires the knowledge of corresponding fundamental solutions, and this idea has a long history dating back to the work of Green [107] and Gauss [95, 96]. Today the resulting boundary integral equations still serve as a major tool for the analysis and construction of solutions to boundary value problems.

The analysis and simulation of multifield problems have recently become one of the most actual and vivid areas of research. Although the individual subproblems of complex technical and physical phenomena often are understood separately, their interaction and coupling create not only new difficulties but also a complete new level and quality of interacting coupled field problems. Presented by leading experts this book includes recent results in these fields from the International Conference on Multifield Problems, April 8-10, 2002 at the University of Stuttgart, Germany.

Presenting the proceedings from the final conference of the Priority Research Programme, this volume covers topics including: the efficient calculation of acoustic fields by BEM; and parallel coupling of FE for 3D elasticity problems.

Diese dreisemestrige Einführung in die Analysis behandelt die Integral- und Differentialrechnung einer und mehrerer Veränderlicher. Daran anschließend werden analytische und einfache numerische Verfahren zur Lösung gewöhnlicher Differentialgleichungen besprochen. Der letzte Teil ist Methoden der komplexen Funktionentheorie gewidmet. Zentrales Anliegen dieses Lehrbuches sind die Entwicklung und Anwendung von praktischen Methoden zur Lösung mathematischer Aufgaben sowie die Konstruktion dieser Lösungen.
