Refined Error Estimates for Radial Basis Function Interpolation

  • Regular Article
  • Published:
Constructive Approximation Aims and scope

We discuss new and refined error estimates for radial-function scattered-data interpolants and their derivatives. These estimates hold on R d, the d-torus, and the 2-sphere. We employ a new technique, involving norming sets, that enables us to obtain error estimates, which in many cases give bounds orders of magnitude smaller than those previously known.
