Mather invariant, distortion, and conjugates for diffeomorphisms of the interval

Hélène Eynard-Bontemps, Andrés Navas

We relate the Mather invariant of diffeomorphisms of the (closed) interval to their asymptotic distortion. For maps with only parabolic fixed points, we show that the former is tri…

Smooth times of a flow in dimension 1

Hélène Eynard-Bontemps

Let $α$ be an irrational number and $I$ an interval of $R$ . If $α$ is Diophantine, we show that any one-parameter group of homeomorphisms of $I$ whose time- $1$ and $α$ map…
