An a posteriori error estimate for the variable-degree Raviart-Thomas method


We propose a new a posteriori error analysis of the variabledegree, hybridized version of the Raviart-Thomas method for secondorder elliptic problems on conforming meshes made of simplexes. We establish both the reliability and efficiency of the estimator for the L2norm of the error of the flux. We also find the explicit dependence of the estimator on the… (More)
