Abstract. We prove that if two germs of diffeomorphisms
preserving a volume, symplectic or contact structure are
tangent to a high enough order and the linearization is
hyperbolic, it is possible to find a smooth change of
variables preserving the same structure that sends one into
the other. This result is a geometric version of Sternberg's
linearization theorem which we recover as a particular case.
An analogous result is also proved for flows.
