Add to ORKGThe main theme of this paper is the approximation on the sphere by weighted sums of spherical harmonics. We give necessary and sufficient conditions on the weights for con-vergence in both the continuous and the Lp cases. Approximation by spherical convolu-tion is a particular and important case that fits into our setting. 1. Introduction an
