Sobolev Spaces, Kernels and Discrepancies over Hyperspheres
Simon Hubbert, Emilio Porcu, Chris. J. Oates +1
This work provides theoretical foundations for kernel methods in the hyperspherical context. Specifically, we characterise the native spaces (reproducing kernel Hilbert spaces) and…

Convergence of sparse grid Gaussian convolution approximation for multi-dimensional periodic function
Simon Hubbert, Janin Jäger, Jeremy Levesley
We consider the problem of approximating -periodic functions by convolution with a scaled Gaussian kernel. We start by establishing convergence rates to functions from p…

Generalised Wendland functions for the sphere
Simon Hubbert, Janin Jäger
In this paper we compute the spherical Fourier expansions coefficients for the restriction of the generalised Wendland functions from dimensional Euclidean space to the (d-1)-d…
