[Formes normales uniques des champs de vecteurs de type Hopf-zéro]
Nous étudions l'unicité des formes normales de champs de vecteurs de type Hopf-zéro dans . Des formes normales uniques dans le cas générique sont données par rapport aux changements de coordonnées et pour l'équivalence orbitale.
We consider normal forms of Hopf-zero vector fields in . Unique normal forms under conjugacy and orbital equivalence for the generic case are given.
