Interval exchange transformation extension of a substitution dynamical system. (English) Zbl 1353.37025
Summary: Let \(\alpha\) be a free group automorphism on \(F_N\) with maximal index and \(\Sigma_{\alpha}\) the associated attracting subshift. We prove that there exists an Interval Exchange Transformation on the circle whose coding factorizes onto \(\Sigma_\alpha\). In the case when there is an explicit construction of the \(\mathbb R\)-tree associated to \(\alpha\), we construct algorithmically such IET. We conclude by giving examples.
