Residual-Based a Posteriori Error Estimators for Algebraic Stabilization Schemes in Convection-Diffusion-Reaction Problems

This work extends the analysis of residual-based a posteriori error estimators in the energy norm to newly proposed algebraic stabilization schemes for convection-diffusion-reaction problems. Numerical simulations on adaptively refined grids demonstrate the higher efficiency of an algebraic stabilization scheme with similar accuracy compared to an algebraic flux correction scheme.
