Abstract

We deal with a linear hyperbolic differential operator of the second order on a bounded planar domain with a smooth boundary. We establish a well-posedness result in case where a mixed, Dirichlet-Neumann, condition is prescribed on the boundary. We focus on the case of a non-homogeneous Dirichlet data and a homogeneous Neumann one. The presented proof is based on a functional theoretical approach and on an approximation argument. Moreover, this work discuss an improvement of a result concerning the range of some operators related to the considered hyperbolic PDE yielding characterizations for the range space of these operators.
