This paper presents several results about isotropic random walks and multiple scattering processes on hyperspheres ${\\mathbb S}^{p-1}$ . It allows one to derive the Fourier expansions on ${\\mathbb S}^{p-1}$ of these processes. A result of unimodality for the multiconvolution of symmetrical probability density functions on ${\\mathbb S}^{p-1}$ is also introduced. Such processes are then studied in the case where the scattering distribution is von Mises–Fisher (vMF). Asymptotic distributions for the multiconvolution of vMFs on ${\\mathbb S}^{p-1}$ are obtained. Both Fourier expansion and asymptotic approximation allow us to compute estimation bounds for the parameters of compound cox processes on ${\\mathbb S}^{p-1}$ . |
