A posteriori error estimates for control problems governed by Stokes equations

摘要

In this paper, we derive a posteriori error estimates for the finite element approximation of distributed optimal control problems governed by the Stokes equations. We obtain a posteriori error estimators for both the state and the control approximation in the L-2 norm and the H-1 norm. These estimates can be used to construct reliable adaptive finite element approximation for the control problems. [References: 51]
