PMThis 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 $\mathbb{R}^3$. 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 realization of the Galerkin BEM, it is essential to
replace time-consuming steps in the numerical solution process with
fast algorithms. In Chapters 5-9 these methods are developed,
analyzed, and formulated in an algorithmic wa

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, schwachbesetzte Darstellung des nicht-lokalen
Operators, Losung der linearen Gleichungssysteme) effiziente
Algorithmen anzugeben und zu analysieren. Das Buch bietet
verschiedene Varianten zur Konzeption einer Vorlesung und eignet
sich auch fur ein Selbststudium.
