The interpolation theory of radial basis functions
B Baxter - arXiv preprint arXiv:1006.2443, 2010 - arxiv.org
In this dissertation, it is first shown that, when the radial basis function is a $p$-norm and $1
< p < 2$, interpolation is always possible when the points are all different and there are at …

Conditionally positive functions andp-norm distance matrices
BJC Baxter - Constructive Approximation, 1991 - Springer
In [4], deep results were obtained concerning the invertibility of matrices arising from radial
basis function interpolation. In particular, the Euclidean distance matrix was shown to be …
