We discretise the optimal control problemby using piecewise linear and continuous finite elements for the space discretisation of the state,and we use the backward Euler scheme for time discretisation. We prove a priori error estimates forthe state, the adjoint-state as well as for the low-regret pointwise optimal control. %K Optimal control problem %K low-regret control %K pointwise control %K finite element method %K a priori error estimates %U http://dx.doi.org/0.1080/00207721.2020.1799107 %P 2597-2609
