Abstract
In this paper, the gradient recovery type a posteriori error estimators for finite 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 where the mesh is regular enough and the exact solution is smooth.
