Zastavnyi operators and positive definite radial functions

Faouzi, Tarik; Porcu, Emilio; Bevilacqua, Moreno; Kondrashuk, Igor

Abstract

we consider a new operator acting on rescaled weighted differences between two members of the class Phi(d) of positive definite radial functions. In particular, we study the positive definiteness of the operator for the Matern, Generalized Cauchy and Wendland families. (C) 2019 Elsevier B.V. All rights reserved.
