We establish a geometric criterion so that the germs at infinity of \phi and the identity function on R belong to a common Hardy field. This criterion is based on the concept of non oscillation. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 Internacional Solutions non oscillantes d’une équation différentielle et corps de Hardy info:eu-repo/semantics/article
