Popis: Pointwise error estimates for approximation on compact homogeneous manifolds using radial kernels are presented. For a \({\mathcal C}^{2r}\) positive definite kernel κ the pointwise error at x for interpolation by translates of κ goes to 0 like ρr, where ρ is the density of the interpolating set on a fixed neighbourhood of x. Tangent space techniques are used to lift the problem from the manifold to Euclidean space, where methods for proving such error estimates are well established.
