Optimal control of problems governed by obstacle type variational inequalities: A dual regularization-penalization approach. (English) Zbl 0919.49003
The authors investigate optimal control problems governed by variational inequalities. They give optimality conditions under classical assumptions using a dual regularized functional to interpret the variational inequality.
