A minimum effort optimal control problem for the undamped wave equation is considered which involves L <Superscript>∞</Superscript>-control costs. Since the problem is non-differentiable a regularized problem is introduced. Uniqueness of the solution of the regularized problem is proven and the convergence of the...</superscript>
