Abstract:
We derive computable bounds of deviations from the exact solution of the stationary Oseen prob-
lem. They are applied to approximations generated by the Uzawa iteration method. Also, we derive an ad-
vanced form of the estimate, which takes into account approximation errors arising due to discretization of
the boundary value problem, generated by the main step of the Uzawa method. Numerical tests con rm our
theoretical results and show practical applicability of the estimates.
