Robust a posteriori error estimators with error-dominated oscillation for the reaction-diffusion equation
F. Tantardini, R. Verfürth
We apply the recent approach of C. Kreuzer and A. Veeser to derive a robust a posteriori error estimator for the reaction-diffusion equation. The estimator together with the corres…

Quasi-monotonicity and Robust Localization with Continuous Piecewise Polynomials
Francesca Tantardini, Rüdiger Verfürth
We consider the energy norm arising from elliptic problems with discontinuous piecewise constant diffusion. We prove that under the quasi-monotonicity property on the diffusion coe…

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…
