Abstract

We give an explicit example of an exotic (non-simplicial), geometric free action of the free group [ ]3 on an ℝ-tree T. We begin by associating an interval translation mapping of the unit interval to an automorphism ψ of [ ]3. We use a result of D. Gaboriau and G. Levitt to obtain an [ ]3-action on an ℝ-tree T. We show that for our particular choice of ψ, the resulting [ ]3-action is minimal, free and exotic.
