English abstract:
A posteriori error estimators and adaptive mesh-refinement have themselves proven to be important
tools for scientific computing. For error control in finite element methods (FEM), there is a
broad variety of a posteriori error estimators available, and convergence as well as optimality of
adaptive FEM is well-studied in the literature. This is, however, in sharp contrast to the boundary
element method (BEM) and to the coupling of FEM and BEM. In our contribution, we present
an easy-to-implement error estimator for some FEM-BEM coupling which, to the best of our
knowledge, has not been proposed in the literature before. The derived mesh-refining algorithm
provides the first adaptive coupling procedure which is mathematically proven to converge.

Keywords:
adaptive algorithm, a posteriori error estimation, finite element method, FEM, boundary element method, BEM
