Abstract
Let X(t) be a centred Gaussian invariant random field on a two-point homogeneous space T. The corresponding Dudley semi-metric is a function of one real variable. We use Abelian and Tauberian theorems to estimate the Dudley semi-metric and find the uniform moduli of continuity of the random field X(t). The series expansion of the multiparameter fractional Brownian motion previously obtained in Chap. 2 is shown to be rate-optimal. We prove a general functional limit theorem for the multiparameter fractional Brownian motion. The functional law of the iterated logarithm, functional Lévy modulus of continuity and many other results are its particular cases. Bibliographical remarks conclude.
