Abstract
In this article, we present convergence rates for summation methods with multipliers related to certain approximation methods on the sphere we previously introduced and discussed in Menegatto and Piantella [Citation13]. The results are based upon spherical moduli of smoothness defined via the Laplace–Beltrami derivative.
