In this paper, the gradient recovery type a posteriori error estimators for ยฎnite element approximations are proposed for irregular meshes. Both the global and the local a posteriori error estimates are derived. Moreover, it is shown that the a posteriori error estimates is asymptotically exact on w

We consider some (anisotropic and piecewise constant) diffusion problems in domains of R 2 , approximated by a discontinuous Galerkin method with polynomials of any fixed degree. We propose an a posteriori error estimator based on gradient recovery by averaging. It is shown that this estimator gives
