Characterization of Strict Positive Definiteness on products of complex spheres
Mario H. Castro, Eugenio Massa, Ana Paula Peron
In this paper we consider Positive Definite functions on products of complex spheres, and we obtain a condition, in terms of the coefficients in their disc pol…

Positive Definite Functions on Complex Spheres and their Walks through Dimensions
Eugenio Massa, Ana Paula Peron, Emilio Porcu
We provide walks through dimensions for isotropic positive definite functions defined over complex spheres. We show that the analogues of Montée and Descente operators as proposed…

Strictly Positive Definite Kernels on a Product of Spheres II
Jean C. Guella, Valdir A. Menegatto, Ana P. Peron
We present, among other things, a necessary and sufficient condition for the strict positive definiteness of an isotropic and positive definite kernel on the cartesian product of a…
