A Quasi-Optimal Crouzeix-Raviart Discretization of the Stokes Equations
Rüdiger Verfürth, Pietro Zanotti
We present a modification of the Crouzeix-Raviart discretization of the Stokes equations in arbitrary dimension which is quasi-optimal, in the sense that the error of the discrete…
A Posteriori Error Estimates for Non-Stationary Non-Linear Convection-Diffusion Equations
Rüdiger Verfürth
Motivated by stochastic convection-diffusion problems we derive a posteriori error estimates for non-stationary non-linear convection-diffusion equations acting as a deterministic…
Robust A Posteriori Error Estimates for Stabilized Finite Element Methods
L. Tobiska, R. Verfürth
There is a wide range of stabilized finite element methods for stationary and non-stationary convection-diffusion equations such as streamline diffusion methods, local projection s…
Robust Localization of the Best Error with Finite Elements in the Reaction-Diffusion Norm
Francesca Tantardini, Andreas Veeser, R"udiger Verf"urth
We consider the approximation in the reaction-diffusion norm with continuous finite elements and prove that the best error is equivalent to a sum of the local best errors on pairs…
