Abstract

We exhibit three classes of compactly supported functions which provide reproducing kernels for the Sobolev spaces Hδ(Rd)H^\delta(\R^d) of arbitrary order δ>d/2.\,\delta>d/2.\, Our method of construction is based on a new class of oscillatory integral transforms that incorporate radial Fourier transforms and Hankel transforms.
