Abstract
We study the boundary element method for weakly singular and hypersing ular integral equations of the first kind on screens resulting from th e Dirichlet and Neumann problems for the Helmholtz equation. it is sho wn that the hp-version with geometrical refined meshes converges expon entially fast in both cases. We underline our theoretical results by n umerical experiments for the pure h-, p-versions, the graded mesh and the hp-version with geometrically refined mesh.
