Error estimates for the numerical approximation of semilinear elliptic control problems with finitely many state constraints

The goal of this paper is to derive some error estimates for the numerical discretization of some optimal control problems governed by semilinear elliptic equations with bound constraints on the control and a nitely number of equality and inequality state constraints. We prove some error estimates f...

Sumario:The goal of this paper is to derive some error estimates for the numerical discretization of some optimal control problems governed by semilinear elliptic equations with bound constraints on the control and a nitely number of equality and inequality state constraints. We prove some error estimates for the optimal controls in the L 1 norm and we also obtain error estimates for the Lagrange multipliers associated to the state constraints as well as for the optimal states and optimal adjoint states.
