The case ofb oundary control is studied. Pointwise constraints on the control and certain equality and set-constraints on the state are considered. Second order sufficient conditions for local optimality of controls are established.}, publisher = {Society for Industrial and Applied Mathematics}, publisher = {SIAM Journal on Control and Optimization, 2000, 38(5), 1369–1391}, title = {Second order sufficient optimality conditions for some state-constrained control problems of semilinear elliptic equations}, author = {Casas Rentería, Eduardo and Tröltzsch, Fredi and Unger, Andreas}, }
