Given two germs of hyperbolic vector fields associated to autonomous ordinary differential equations   and  , where  , and   and   are   matrices, we prove that under some algebraic conditions on the eigenvalues of the matrices and genericity condition on the nonlinear terms, they are at least   conjugate if and only if   and   are similar.

Etant donnés deux germes de champs de vecteurs hyperboliques définis par des équations différentielles autonomes   et  , où  ,   et   sont des matrices d'ordre  , on démontre que, sous certaines conditions algébriques sur les valeurs propres des matrices et des conditions de non dégénérescensce des terms nonlinéaires, ils sont au moins   conjuqués si et seulement si   et   sont semblables.
