Conditional quasi-optimal error estimate for a finite element discretization of the -Navier-Stokes equations: The case
Alex Kaltenbach, Michael Růžička
In this paper, we derive quasi-optimal error estimates for the kinematic pressure for a Finite Element (FE) approximation of steady systems of -Navier-Stokes…

Note on quasi-optimal error estimates for the pressure for shear-thickening fluids
Alex Kaltenbach, Michael Růžička
In this paper, we derive quasi-optimal a priori error estimates for the kinematic pressure for a Local Discontinuous Galerkin (LDG) approximation of steady systems of -Navier-St…

Quasi-optimal Discontinuous Galerkin discretisations of the -Dirichlet problem
J. Blechta, P. A. Gazca-Orozco, A. Kaltenbach +1
The classical arguments employed when obtaining error estimates of Finite Element (FE) discretisations of elliptic problems lead to more restrictive assumptions on the regularity o…
