Strong convergence of difference approximations for problems of boundary control and observation for the wave equation
The author considers the mutually dual problems of Dirichlet control and Neumann observation for the wave equation with variable coefficients. A variational method for solving discrete problems of control and observation is suggested that converges strongly not only in the functional but also in the argument over the entire class of controllability and observability.
