Aperiodic order and spherical diffraction, II: translation bounded measures on homogeneous spaces
Artikel i vetenskaplig tidskrift, 2021

We study the auto-correlation measures of invariant random point processes in the hyperbolic plane which arise from various classes of aperiodic Delone sets. More generally, we study auto-correlation measures for large classes of Delone sets in (and even translation bounded measures on) arbitrary locally compact homogeneous metric spaces. We then specialize to the case of weighted model sets, in which we are able to derive more concrete formulas for the auto-correlation. In the case of Riemannian symmetric spaces we also explain how the auto-correlation of a weighted model set in a Riemannian symmetric space can be identified with a (typically non-tempered) positive-definite distribution on R-n. This paves the way for a diffraction theory for such model sets, which will be discussed in the sequel to the present article.
