Abstract

An open-loop system of a multidimensional wave equationwith variable coefficients, partial boundary Dirichlet control andcollocated observation is considered. It is shown that the system iswell-posed in the sense of D. Salamon and regular in the sense of G.Weiss. The Riemannian geometry method is used in the proof ofregularity and the feedthrough operator is explicitly computed.
