Tóm tắt: A class of optimal control problems governed by semilinear parabolic equations mixed pointwise are considered. We give some criteria under which Lagrange multipliers belong to -spaces. We then establish first and second-order optimality conditions of KKT-type for the problem. Moreover, we show that if the initial value is good enough and boundary sátifies the property of positive geometric density, then multipliers and optimal solutions are H"{o}lder continuous.
