• A Posteriori Modelling-Discretization Error Estimate for Elliptic Problems with L ∞-Coefficients 

  Weymuth, Monika; Sauter, Stefan; Repin, Sergey (Walter de Gruyter GmbH, 2017)

  We consider elliptic problems with complicated, discontinuous diffusion tensor A0. One of the standard approaches to numerically treat such problems is to simplify the coefficient by some approximation, say Aε, and to ...

• A posteriori error bounds for approximations of the oseen problem and applications to the uzawa iteration algorithm 

  Nokka, Marjaana; Repin, Sergey (Walter de Gruyter GmbH, 2014)

  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 ...

• 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 ...
