چکیده

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.

Rényi Function for Multifractal Random Fields

This paper presents the basic scheme and the log-normal, log-gamma and lognegative inverted gamma scenarios to establish the Rényi function for infinite products of homogeneous isotropic random fields on R. We also present our scheme for a field on the spherical surface in R, which is related to the CMRB problem in Cosmology. In the presentation, we need to employ spherical harmonics for some c...

Apparent diffusion coefficients from high angular resolution diffusion imaging: estimation and applications.

High angular resolution diffusion imaging has recently been of great interest in characterizing non-Gaussian diffusion processes. One important goal is to obtain more accurate fits of the apparent diffusion processes in these non-Gaussian regions, thus overcoming the limitations of classical diffusion tensor imaging. This paper presents an extensive study of high-order models for apparent diffu...

THE EMPIRICAL PROCESS ON GAUSSIAN SPHERICAL HARMONICS By Domenico Marinucci 1 and Mauro Piccioni

We establish weak convergence of the empirical process on the spherical harmonics of a Gaussian random field in the presence of an unknown angular power spectrum. This result suggests various Gaus-sianity tests with an asymptotic justification. The issue of testing for Gaussianity on isotropic spherical random fields has recently received strong empirical attention in the cosmological literatur...

Increasing Domain Asymptotics for the First Minkowski Functional of Spherical Random Fields

The restriction to the sphere of an homogeneous and isotropic random field defines a spherical isotropic random field. This paper derives central and non-central limit results for the first Minkowski functional subordinated to homogeneous and isotropic Gaussian and chi-squared random fields, restricted to the sphere in R. Both scenarios are motivated by their interesting applications in the ana...

A spatiospectral localization approach to estimating potential fields on the surface of a sphere from noisy, incomplete data taken at satellite altitudes

Satellites mapping the spatial variations of the gravitational or magnetic fields of the Earth or other planets ideally fly on polar orbits, uniformly covering the entire globe. Thus, potential fields on the sphere are usually expressed in spherical harmonics, basis functions with global support. For various reasons, however, inclined orbits are favorable. These leave a “polar gap”: an antipoda...
