Complex Rotation Numbers And Renormalization
The complex rotation number is an invariant related to the dynamics of an analytic circle diffeomorphism f. It produces a nice fractal set ``bubbles'' analogous to Arnold's tongues. I will explain how the renormalization operator makes the ``bubbles'' self-similar and controls their sizes.
