Dimension hopping and families of strictly positive definite zonal basis functions on spheres
Positive definite functions of compact support are widely used for radial basis function approximation as well as for estimation of spatial processes in geostatistics. Several constructions of such functions for Rd ...
Thinplate splines on the sphere
© 2018, Institute of Mathematics. All rights reserved. In this paper we give explicit closed forms for the semi-reproducing kernels associated with thinplate spline interpolation on the sphere. Polyharmonic or thinplate ...
