Apriori and aposteriori error estimates fo Navier-Stokes equations applied to incompressible flows
In the first part we investigate a posteriori error estimates to solve an incompressible flow problem in a domain that cause singularities in the solution. Second part stands on the result on the asymptotics of the solution in the v...

Stabilization of FEM for incompressible flows by modified GLS algorithm
Within the framework of the finite element method problems with corner-like singularities are most often solved by the adaptive strategy - the mesh near the corners is refined according to the aposteriori error estimates. In this pa...
