Sparse Convolution Quadrature for Time Domain Boundary Integral Formulations of the Wave Equation besent two ways of reducing these costs. The first is an a priori cutoff strategy, which allows to replace a substantial part of the matrices by 0. The second is a panel clustering approximation, which further reduces the storage and computational cost by approximating subblocks by low rank matrices.

Fast Multipole Methods and Applications,e computational costs and memory requirements from quadratic order to almost linear ones. Three different approaches to realize the boundary integral operators of linear elastostatics by the fast multipole method are described and numerical examples are given for one of these approaches.

Louisiana‘s Response to Extreme Weatherfs are based on first order approximation operators and inverse estimates. For a finer and finer fine mesh . ., the estimator becomes asymptotically exact. The abstract framework is applicable to a finite element method for the Laplace equation, boundary element methods for Symm’s and the hypersingular integral equation or transmission problems.

Boundary Element Methods for Eddy Current Computation,ed. They give rise to coupled variational problems that are elliptic in suitable trace spaces. This implies quasi-optimal convergence of conforming Galerkin boundary element methods, which make use of div.-conforming trial spaces for surface currents.
