Solutions non oscillantes d’une équation différentielle et corps de Hardy
[Non-oscillating solutions of a differential equation and Hardy fields]
Annales de l'Institut Fourier, Volume 57 (2007) no. 6, pp. 1825-1838.

Let ϕ:xϕ(x),x0 be a solution of an algebraic differential equation of order n, P(x,y,y ,...,y (n) )=0. We establish a geometric criterion so that the germs at infinity of ϕ and the identity function on belong to a common Hardy field. This criterion is based on the concept of non oscillation.

Soit ϕ:xϕ(x),x0 une solution à l’infini d’une équation différentielle algébrique d’ordre n, P(x,y,y ,...,y (n) )=0. Nous donnons un critère géométrique pour que les germes à l’infini de ϕ et de la fonction identité sur appartiennent à un même corps de Hardy. Ce critère repose sur le concept de non oscillation.
