Abstract
Recently, a robust approximation error estimate and a corresponding inverse inequality for B-splines of maximum smoothness have been shown, both with constants independent of the spline degree. We use these results to construct multigrid solvers for discretizations of two-dimensional problems based on tensor product B-splines with maximum smoothness which exhibit robust convergence rates.
