Let be a solution of an algebraic differential equation of order , . We establish a geometric criterion so that the germs at infinity of and the identity function on belong to a common Hardy field. This criterion is based on the concept of non oscillation.
Soit une solution à l’infini d’une équation différentielle algébrique d’ordre , . Nous donnons un critère géométrique pour que les germes à l’infini de et de la fonction identité sur appartiennent à un même corps de Hardy. Ce critère repose sur le concept de non oscillation.
Mot clés : oscillation, corps de Hardy, semi-algébrique, pfaffien
