RT info:eu-repo/semantics/article T1 Solutions non oscillantes d’une équation différentielle et corps de Hardy A1 Blais, François A1 Moussu, Robert A1 Sanz, Fernando K1 oscillation, corps de Hardy, semi-algébrique, pfaffien AB Let \phi: x -> \phi (x), x > 0 be a solution of an algebraic differentialequation of order n, P(x, y, y0, . . . , y(n)) = 0. We establish a geometric criterion sothat the germs at infinity of \phi and the identity function on R belong to a commonHardy field. This criterion is based on the concept of non oscillation.
