Unbounded Positive Definite Functions

Canadian Journal of Mathematics, 1969
Let G be an abelian group, written additively. A complexvalued function ƒ, defined on G, is said to be positive definite if the inequality1holds for every choice of complex numbers C1, …, cn and S1, …, sn in G. It follows directly from (1) that every positive definite function is bounded. Weil (9, p.

On matrix valued square integrable positive definite functions [PDF]

Monatshefte Fur Mathematik, 2015
. In this paper, we study matrix valued positive definite functions on a unimodular group. We generalize two important results of Godement on L2 positive definite functions. We show that a matrix-valued continuous L2 positive definite function can always

Finite range decompositions of positive-definite functions [PDF]

Journal of Functional Analysis, 2006
We give sufficient conditions for a positive-definite function to admit decomposition into a sum of positive-definite functions which are compactly supported within disks of increasing diameters Ln.

Distribution Functions and Positive-Definite Functions

The Annals of Mathematics, 1934
The distribution of the values of a real almost periodic function or more generally of an almost periodic curve in several dimensions has been investigated lately by Wintner, Haviland and others.' One of the methods applied by Wintner depends on the use of Fourier transforms and is as such a standard method in the theory of probability.
