Nous présentons un exemple de contraction inversible et régulière dans un espace de Hilbert de dimension infinie qui n'est pas localement C1-linéarisable autour de son point fixe.

We present an example of a smooth invertible contraction in an infinite-dimensional Hilbert space that is not locally C1-linearizable near its fixed point.
