Tóm tắt: In this seminar, we present some results on  second-order optimality conditions and regularity of Lagrange multipliers for a class of optimal control problems governed by semilinear elliptic equations with mixed pointwise constraints in which controls act both in the domain and on the boundary. We give some criteria under which the optimality conditions is of KKT type and the multipliers are of $L^p$-spaces. Moreover, we show that the multipliers are Lipschitz continuous functions.
