Highly Localized RBF Lagrange Functions for Finite Difference Methods on Spheres
Wolfgang Erb, Thomas Hangelbroek, Francis J. Narcowich +2
The aim of this paper is to show how rapidly decaying RBF Lagrange functions on the spheres can be used to create effective, stable finite difference methods based on radial basis…
Better bases for kernel spaces
E. J. Fuselier, T. C. Hangelbroek, F. J. Narcowich +2
In this article we investigate the feasibility of constructing stable, local bases for computing with kernels. In particular, we are interested in constructing families $(b_ξ)_{ξ\i…
Cardinal Interpolation with Gaussian Kernels
Thomas Hangelbroek, Wolodymyr Madych, F. J. Narcowich +1
In this paper, interpolation by scaled multi-integer translates of Gaussian kernels is studied. The main result establishes Sobolev error estimates and shows that the error i…
