Pointwise Fourier inversion of distributions on spheres

Francisco Javier González Vieli

Received July 27, 2016.   First published October 6, 2017.

Abstract:  Given a distribution $T$ on the sphere we define, in analogy to the work of Łojasiewicz, the value of $T$ at a point $\xi$ of the sphere and we show that if $T$ has the value $\tau$ at $\xi$, then the Fourier-Laplace series of $T$ at $\xi$ is Abel-summable to $\tau$.
Keywords:  distribution; sphere; Fourier-Laplace series; Abel summability
