Abstract

For the Voter Model on Zd, d3, we show that the (extremal) stationary distributions are isomorphic to Bernoulli shifts, and answer an open question asked by Steif and Tykesson in (ALEA Lat. Am. J. Probab. Math. Stat. 16 (2019) 899–955). The proof gives explicit constructions of the stationary distributions as factors of IID processes on Zd.

Funding Statement

This work was supported by an NSF career award (DMS-1352013), a Simons Investigator grant and a MacArthur Fellowship.

Acknowledgments

The authors would like to thank Jeff Steif for suggesting the problem. We are also very thankful for the many helpful suggestions from an anonymous referee, who pointed out an error in the first version of this paper, and suggested a simplification in the construction of W0 and W1 in Section 2.2.
