Abstract. In this paper we study an identification problem for physical parameters associated with damped Klein-Gordon equation with Neumann boundary conditions. The existence, uniqueness, and continuous dependence of weak solution of Klein-Gordon equations are established. The method of transposition is used to prove the Gâteaux differentiability of the solution map. The Gâteaux differential of the solution map is characterized. The optimal parameters are established.
