Query: Optimal error estimation for H(curl)-conforming p-interpolation in two
  dimensions   In this paper we prove an optimal error estimate for the H(curl)-conforming
projection based p-interpolation operator introduced in [L. Demkowicz and I.
Babuska, p interpolation error estimates for edge finite elements of variable
order in two dimensions, SIAM J. Numer. Anal., 41 (2003), pp. 1195-1208]. This
result is proved on the reference element (either triangle or square) K for
regular vector fields in H^r(curl,K) with arbitrary r>0. The formulation of the
result in the H(div)-conforming setting, which is relevant for the analysis of
high-order boundary element approximations for Maxwell's equations, is provided
as well.
