Markovianity and the Thompson Group F (Pre-published version)

Abstract

We show that representations of the Thompson group F in the automorphisms of a noncommutative probability space yield a large class of bilateral stationary noncommutative Markov processes. As a partial converse, bilateral stationary Markov processes in tensor dilation form yield representations of F. As an application, and building on a result of Kuemmerer, we canonically associate a representation of F to a bilateral stationary Markov process in classical probability.
