First and second order optimality conditions are obtained, in the presence of constraints on the controls, which can be either pointwise in space-time, or pointwise in time and L2 in space. These results rely on a new L∞ estimate for nonlinear parabolic equations in an essential manner.}, organization = {Eduardo Casas was supported by MCIN/ AEI/10.13039/501100011033/ under research Project PID2020-114837GB-I00.}, publisher = {Springer}, publisher = {Applied Mathematics and Optimization, 2023, 88(2), 47}, title = {Infinite horizon optimal control for a general class of semilinear parabolic equations}, author = {Casas Rentería, Eduardo and Kunisch, Karl}, }
