This book is an introduction to the mathematical analysis of p- and hp-finite elements applied to elliptic problems in solid and fluid mechanics. In the last decade the p-, hp-, and spectral element methods have emerged as efficient and robust approximation methods for several classes of problems in this area. The aim of this book is to establish the exponential convergence of such methods for problems with the piecewise analytic solutions which typically arise in engineering. It looks at the variational formulation of boundary value problems with particular emphasis on the regularity of the...

In diesem ersten Lehrbuch uber Randelementmethoden werden schnelle numerische Losungsverfahren entwickelt und analysiert. Daruber hinaus wird auch die effiziente Implementierung thematisiert, wobei besonderer Wert auf eine mathematisch-saubere Herleitung und Analyse der Integralgleichungen gelegt wird. Im Vordergrund steht die Galerkin-Diskretisierung der Integralgleichungen mit Randelementen, die fur die meisten Anwendungen die geeignetste Diskretisierungsmethode ist. Eine Zielsetzung der Darstellung ist es, fur alle Teilschritte der Methode (Berechnung der Matrixkoeffizienten,...

This work presents a thorough treatment of boundary element methods (BEM) for solving strongly elliptic boundary integral equations obtained from boundary reduction of elliptic boundary value problems in $mathbb DEGREES3$. The book is self-contained, the prerequisites on elliptic partial differential and integral equations being presented in Chapters 2 and 3. The main focus is on the development, analysis, and implementation of Galerkin boundary element methods, which is one of the most flexible and robust numerical discretization methods for integral equations. For the efficient...
