Spectra of stationary processes on Z

Probability 2017-01-13 v1 Classical Analysis and ODEs

Abstract

We will discuss a somewhat striking spectral property of finitely valued stationary processes on Z that says that if the spectral measure of the process has a gap then the process is periodic. We will give some extensions of this result and raise several related questions.
