Ingham type approach for uniform observability inequality of the semi-discrete coupled wave equations
This article concerns an observability inequality for a system of coupled wave equations for the continuous models as well as for the space semi-discrete finite difference approximations. For finite difference and standard finite elements methods on uniform numerical meshes it is known that a nu...
