We show a new functional analytic formulation for half-entire parabolic solutions of a class of systems of ODEs driven by singular potentials. A key point for this is represented by the choice of a suitable functional space supporting an Hardy-type inequality. Applications to various equations of Celestial Mechanics are presented, yielding, in a perturbative setting, the existence of parabolic solutions asymptotic to a (possibly non-minimal) prescribed central configuration.

Joint work with Walter Dambrosio (University of Turin), Guglielmo Feltrin (University of Udine) and Susanna Terracini (University of Turin).
