We propose and analyze an overlapping Schwarz preconditioner for the p and hp boundary element method for the hypersingular integral equation in 3D.We consider surface triangulations consisting of triangles. We prove a bound for the condition number that is independent of the mesh size h and polynomial order p. Additionally,we provide an extension to adaptive meshes based on a local multilevel preconditioner for the lowest order space. Numerical experiments on different geometries support our theoretical findings.
