abstract = {<p style="text-align: justify;">Adaptive finite element approximation for a constrained optimal
control problem is studied. A posteriori error estimators equivalent to the $L^2$ norm of the approximation error are derived both for the state and the control
approximation, which are particularly suitable for an adaptive multi-mesh finite
element scheme and applications where $L^2$ error is more important. The error
estimators are then implemented and tested with promising numerical results.</p>},
