TheNeumann Laplacian on spaces of continuous functions


Abstract


If \Omega \subset \mathbb{R}^N is an open set, one can always define the Laplacian with Neumann boundary conditions \Delta^N_\Omega on L^2(\Omega). It is a self-adjoint operator generating a C_O-semigroup on L^2(\Omega). Considering the part \Delta^N_\Omega,c of \Delta^N_\Omega in C(\overline{\Omega}),we ask under which conditions on it generates a C_O-semigroup.
