A general form of the covariance matrix function is derived in this paper for a vector random field that is isotropic and mean square continuous on a compact connected two-point homogeneous space and stationary on a temporal domain.

“…In this paper, we prove several theorems concerning relations between the asymptotic behavior of the spectral measure of random fields ξ(x) and η(x) at infinity and the asymptotic behavior of the variance of increments near zero. Other kinds of Abelian and Tauberian theorems for homogeneous and isotropic random fields are studied in [5,6,8,11,19].…”
Abstract. We consider centered mean-square continuous random fields for which the variance of increments between two points depends only on the distance between these points. Relations between the asymptotic behavior of the variance of increments near zero and the asymptotic behavior of the spectral measure of the field near infinity are investigated. We prove several Abelian and Tauberian theorems in terms of slowly varying functions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
