Abstract
The purpose of this article is to construct highly localized summability kernels on the unit sphere in that are restrictions to the sphere of linear combinations of a small number of shifts of the fundamental solution of the Laplace equation (Newtonian kernel) with poles outside the unit ball in . The same problem is also solved for the subspace in .
