ERROR AND STABILITY ESTIMATES FOR SURFACE-DIVERGENCE FREE RBF INTERPOLANTS ON THE SPHERE
Additional Document Info
Recently, a new class of surface-divergence free radial basis function interpolants has been developed for surfaces in . In this paper, several approximation results for this class of interpolants will be derived in the case of the sphere, . In particular, Sobolev-type error estimates are obtained, as well as optimal stability estimates for the associated interpolation matrices. In addition, a Bernstein estimate and an inverse theorem are also derived. Numerical validation of the theoretical results is also given.
