Abstract

We show that representations of the Thompson group FF 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 FF. As an application, and building on a result of K\"ummerer, we canonically associate a representation of FF to a bilateral stationary Markov process in classical probability.
