We consider the the interpolation problem between and , where Ω is a polygonal domain in and is the subspace of functions in H1(Ω) which vanish on the Dirichlet part (Ω)D of the boundary of Ω. The main result is that the interpolation spaces and coincide. An application of this result to a nonconforming finite element problem is presented.
