Abstract
We investigate the p-version of the boundary element Galerkin method for a first kind integral equation. We present a-priori driven algorithms which yield sparse Galerkin matrices and do not destroy the convergence properties of the boundary element method. Further, we show that the additive Schwarz method is nearly an optimal preconditioner for the Galerkin systems. Numerical results confirm the efficiency of our methods.
