A posteriori L∞(L∞)-error estimates for finite-element approximations to parabolic optimal control problems

We derive space–time a posteriori error estimates of finite-element method for the linear parabolic optimal control problems in a convex bounded polyhedral domain. The variational discretization is used to approximate the state and co-state variables with the piecewise linear and continuous function...
