Interval exchange transformations with discrete spectrum

Vortrag von Prof. Dr. Pascal Hubert

We know from a result by Avila and Forni that almost every interval exchange transformation is weakly-mixing. Until very recently, no (non trivial) example with discrete spectrum was known. In this talk, I will describe two families of interval exchange transformations which are conjugate to rotations of the two dimensional torus.
