Abstract:
Natural mechanical systems describing the motion of a particle on a two-dimensional Riemannian manifold of revolution in the field of a central smooth potential are studied in the paper. A complete classification of such Riemannian manifolds and potentials on them possessing the strengthened Bertrand property, i.e., any orbit not contained in any meridian is closed, is obtained.
Key words:Bertrand's Riemannian manifold, surface of revolution, equator, Tannery's manifold, the Maupertuis principle.
