Simple a posteriori error estimators for the h-version of the boundary element method

The h-h/2-strategy is one very basic and well-known technique for the a posteriori error estimation for Galerkin discretizations of energy minimization problems. Let denote the exact solution. One then considers H := h - h/2 to estimate the error - h , where h is a Galerkin solution with respect to a mesh Th and h/2 is a Galerkin solution for a mesh Th/2 obtained from uniform refinement of Th. We stress that H is always efficient
