Indirect boundary observability of semi-discrete coupled wave equations
Electronic Journal of Differential Equations, 2018 This work concerns the indirect observability properties for the finite-difference space semi-discretization of the 1-d coupled wave equations with homogeneous Dirichlet boundary conditions. We assume that only one of the two components of the unknown
