Some characterizations of the spherical harmonics coefficients for isotropic random fields
Abstract
Description
In this paper we provide some simple characterizations for the spherical harmonics coefficients of an isotropic random field on the sphere. The main result is a characterization of isotropic gaussian fields through independence of the coefficients of their development in spherical harmonics.
