A uniform dichotomy for generic SL (2,ℝ) cocycles over a minimal base
[Une dichotomie uniforme pour des cocycles à valeurs dans SL (2,ℝ) au-dessus d’une dynamique minimale]
Bulletin de la Société Mathématique de France, Tome 135 (2007) no. 3, pp. 407-417.

On considère des cocycles continus à valeurs dans SL (2,ℝ) au-dessus d’un homéomorphisme minimal d’un ensemble compact de dimension finie. On montre que le cocycle générique soit est uniformément hyperbolique, soit possède une croissance sous-exponentielle uniforme.

We consider continuous SL (2,ℝ)-cocycles over a minimal homeomorphism of a compact set K of finite dimension. We show that the generic cocycle either is uniformly hyperbolic or has uniform subexponential growth.
