Basis on the sphere in multidimensions

I'm interested if there is the explicit forms of basis functions in $L^2(S^n), n\geq 3$. For $n=1, n=2$ basis functions are well known: $\{e^{ik\phi}\}_{k\in\mathbb{Z}}$, $\{p^{|m|}_n(\cos \gamma) e …

Calderon-Zygmund theorem for the kernel of spherical harmonics

I don't want to write precisely the formulation of the Calderon-Zygmund theorem for singular integrals. The details are not so important here. So I consider the operator $T$ given by the following f …
