The Lagrange problem concerning the mean motion of perihelions
Abstract
It is shown that the mean motion of perihelions in the Lagrange sense on a nonresonance manifold is a function of frequencies that is uniformly continuous over the initial phases. The analysis is carried out in the first approximation of perturbation theory, when the squares of the eccentricities can be neglected as compared with the eccentricities themselves.
