M.Sc. Marjaana Nokka defends her doctoral dissertation in Information Technology ”A posteriori error estimates for variational problems in the theory of viscous fluids. Opponent Dr. Jan Valdman (Institute of Information Theory and Automation, Prague) and custos Professor Pekka Neittaanmäki (University of Jyväskylä). The doctoral dissertation is held in English.

The papers included in the thesis are focused on functional type a posteriori error estimates for Stokes problem, Stokes problem with friction type boundary condition, Oseen problem, and anti-plane Bingham problem. The papers present and justify special forms of these estimates which are suitable for the approximations generated by the Uzawa algorithm. Estimates of the first type use solutions obtained on the steps of the Uzawa algorithm. Estimates of the second type operate with finite element solutions and therefore are fully computable.
