Levitt, Gilbert Dynamics for rotation pseudogroups. (La dynamique des pseudogroupes de rotations.) (French) Zbl 0791.58055 Invent. Math. 113, No. 3, 633-670 (1993). We study dynamical systems on the circle generated by a finite number of partially defined rotations. We construct new examples with all orbits dense (this leads to non-simplicial free actions of free groups on \(\mathbb R\)-trees). We study the generic dynamics for these pseudogroups and their 1-parameter families. We show that, in suitable 2-parameter families, the set of pseudogroups having a dense orbit is a Sierpiński curve. We generalize results on interval exchange transformations obtained by Boshernitzan, Veech, Rips.
