FEEDTHROUGH OPERATOR FOR LINEAR ELASTICITY SYSTEM WITH BOUNDARY CONTROL AND OBSERVATION
We are concerned with the feedthrough operator for the open-loop system of linear elasticity with Dirichlet boundary control and collocated observation. This system has been known to be regular in the sense of G. Weiss. In this paper, the analytic expression of the corresponding feedthrough operator is presented by means of differential geometry and Fourier transform methods.
