Special Session 124: Renormalization and universality in low-dimensional dynamics: from computer experiment to proof. Dedicated to the memory of Oscar Lanford III
Contents
We will discuss the $C^s$ conjugacy between $C^\ell$ vector fields close to constant and diophantine vectors. We use a renormalization method based on a multidimensional continued fraction expansion in order to get bounds on $\ell$ and $s$.
