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.

On a posteriori error bounds for approximations of the generalized Stokes problem generated by the Uzawa algorithm
Anjam, Immanuel; Nokka, Marjaana; Repin, Sergey (De Gruyter, 2012)In this paper, we derive computable a posteriori error bounds for approximations computed by the Uzawa algorithm for the generalized Stokes problem. We show that for each Uzawa iteration both the velocity error and the ... -

Functional a posteriori Error Estimates for Time-periodic Parabolic Optimal Control Problems
Langer, Ulrich; Repin, Sergey; Wolfmayr, Monika (Taylor & Francis Inc., 2016)This article is devoted to the a posteriori error analysis of multiharmonic finite element approximations to distributed optimal control problems with time-periodic state equations of parabolic type. We derive a posteriori ...
