Robust equilibrated a posteriori error estimators for the Reissner-Mindlin system
Emmanuel Creusé, Serge Nicaise, Emmanuel Verhille
We consider a conforming finite element approximation of the Reissner-Mindlin system. We propose a new robust a posteriori error estimator based on H(div) conforming finite element…

A posteriori error estimator based on gradient recovery by averaging for convection-diffusion-reaction problems approximated by discontinuous Galerkin methods
Emmanuel Creusé, Serge Nicaise
We consider some (anisotropic and piecewise constant) convection-diffusion-reaction problems in domains of R2, approximated by a discontinuous Galerkin method with polynomials of a…
