On the projective derivative cocycle for circle diffeomorphisms
Andrés Navas, Mario Ponce
We study the projective derivative as a cocycle of Möbius transformations over groups of circle diffeomorphisms. By computing precise expressions for this cocycle, we obtain severa…

(Un)distorted diffeomorphisms in different regularities
Andrés Navas
We build the first examples of diffeomorphisms that are distorted in a group of diffeomorphisms yet undistorted in the corresponding group of diffeomorphisms, where $r…
