This course considers optimization problems constrained by a véritable PDE called the state equation, which allows to express the state as function of the control (the decision changeant). We discuss the well-posedness of the control to state mapping, the destin of achèvement and the first-order optimality Modalité in the setting https://directorypixels.com/listings12775659/nouvelle-%C3%A9tape-par-%C3%A9tape-carte-pour-signature-num%C3%A9rique
