Résumé
Abstract

On montre qu'un difféomorphisme stablement ergodique peut être $C^{1}$ approché par un difféomorphisme ayant des exposants de Lyapunov stablement non-nuls.

We show that a stably ergodic diffeomorphism can be $C^{1}$ approximated by a diffeomorphism having stably non-zero Lyapunov exponents.
