Abstract: Baumslag-Solitar groups are given by BS(m,n) ≅ ⟨a,b : abm=bna⟩. After a short introduction we fix the group BS(2,3) and investigate random walks on it. The Poisson-Fürstenberg boundary is a measure space associated to such a random walk which, roughly speaking, models the long time behaviour of the random walk. Our goal is to describe this boundary geometrically. In the past, we have always assumed that our random walk is driven by a measure whose support consists of the standard generators a and b and their inverses. Now, we show how to proceed from nearest neighbour to finite range random walks. In particular, it turns out that, in some sense, our result for nearest neighbour random walks does not depend on the choice of a finite generating set of the group BS(2,3). [hide abstract] | |
