  • Elliptic equations, mixed Dirichlet-Neumann conditions, $L^infty$-estimates


In this paper, we prove $L^infty$-estimates for solutions of divergence operators in case of mixed boundary conditions. In this very general setting, the Dirichlet boundary part may be arbitrarily wild, i.e. no regularity conditions have to be imposed on it.
