Spectral disjointness of powers of Interval Exchange Transformations
Salle de séminaire M.0.1.
Firstly, I will present the definition of spectral disjointness of two automorphisms and show a criterion which can be used to distinguish this property. Secondly, I will show how to see that powers of a generic interval exchange transformation of three intervals satisfy the asumptions of the criterion.
The result is based on a joint work with Adam Kanigowski.
