Nonlinear $n$ -term approximation of harmonic functions from shifts of the Newtonian Kernel

Kamen Ivanov, Pencho Petrushev

A basic building block in Classical Potential Theory is the fundamental solution of the Laplace equation in $R^{d}$ (Newtonian kernel). The main goal of this article is to…

Highly localized kernels on the sphere induced by Newtonian kernels

Kamen Ivanov, Pencho Petrushev

The purpose of this article is to construct highly localized summability kernels on the unit sphere in $R^{d}$ that are restrictions to the sphere of linear combinations of…
