de Rham diagram for hp finite element spaces
We prove that the hp finite elements for H(curl) spaces, introduced in [1], fit into a general deRham diagram involving hp approximations. The corresponding interpolation operators generalize the notion of hp interpolation introduced in [2] and are different from the classical operators of Nedelec and Raviart-Thomas.
