摘要

The setting is an ergodic dynamical system (X,μ) whose points are themselves uniformly discrete point sets Λ in some space and whose group action is that of translation of these point sets by the vectors of . Steven Dworkin’s argument relates the diffraction of the typical point sets comprising X to the dynamical spectrum of X. In this paper we look more deeply at this relationship, particularly in the context of point processes.
