On a posteriori error estimators in the infinite element method on anisotropic meshes
Electronic transactions on numerical analysis, Tome 8 (1999), pp. 36-45
On anisotropic finite element meshes, the standard residual based error indicator is derived and it is proved that it is not efficient if the aspect ratio deteriorates. For a nonlocal error indicator it is proved that it is reliable and efficient independent of the aspect ratio. This is also confirmed by some numerical calculations.
