Interpolation error estimates for edge elements on anisotropic meshes
The classical error analysis for Nédélec edge interpolation requires the so-called regularity assumption on the elements. However, in Nicaise (2001, SIAM J. Numer. Anal., 39, 784-816) optimal error estimates were obtained for the lowest order case under the weaker hypothesis of the maximum angle con...
