On rigidity theory for nonlinear interval exchange transformations: In this talk we shall report on recent progress in rigidity theory for nonlinear interval exchange transformations corresponding to cyclic permutations. Such maps can be viewed as circle homeomorphisms with multiple break points. We shall discuss both recent results on rigidity and renormalization of such maps in case of one break point (joint with S. Kocic and A. Teplinsky), and an extension to the multiple-break setting (based on work in progress with A. Teplinsky).
