Error Estimates for the Interpolation and Approximation of Gradients and Vector Fields on Protected Delaunay Meshes in $$\mathbb {R}^{d}$$

Abstract One frequently needs to interpolate or approximate gradients on simplicial meshes. Unfortunately, there are very few explicit mathematical results governing the interpolation or approximation of vector-valued functions on Delaunay meshes in more than two dimensions. Most...
