The space of actions of on a one-dimensional manifold is path-connected
Hélène Eynard-Bontemps, Andrés Navas
We show path-connectedness for the space of actions by diffeomorphisms with absolutely continuous derivative on both the closed interval and the circle. We als…
On residues and conjugacies for germs of 1-D parabolic diffeomorphisms in finite regularity
Hélène Eynard-Bontemps, Andrés Navas
We study conjugacy classes of germs of non-flat diffeomorphisms of the real line fixing the origin. Based on the work of Takens and Yoccoz, we establish results that are sharp in t…
On the failure of linearization for germs of hyperbolic vector fields in dimension one
Hélène Eynard-Bontemps, Andrés Navas
We investigate conjugacy classes of germs of hyperbolic 1-dimensional vector fields at the origin in low regularity. We show that the classical linearization theorem of Sternberg s…
(Arc-)connectedness for the space of -actions by diffeomorphisms on 1-dimensional manifolds
Hélène Eynard-Bontemps, Andrés Navas
We deal with the general problem of connectedness for the space of actions by (orientation-preserving) diffeomorphisms of a compact 1-manifold. We prove two results.…
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…
