A finite number of only time-dependent controls intervening at dis joint positions in the space domain are considered. The controls are subject to integral constraints and a term is included in the cost functional that promotes control sparsity. The existence of optimal controls is proven, first and second order optimality conditions are derived, and the approximation by finite horizon control problems is addressed.}, organization = {The first author was partially supported by MCIN/ AEI/10.13039/501100011033/ under research project PID2020-114837GB-I00.}, publisher = {De Gruyter Brill}, publisher = {Control and Cybernetics, 2024, 53(1), 11-42}, title = {Temporally sparse controls for infinite horizon semilinear parabolic equations with norm constraints}, author = {Casas RenterĂ­a, Eduardo and Kunisch, Karl}, }
