Abstract:
The problem of two particles with central interaction on simply connected surfaces of a constant curvature was considered. Due to the absence in this case of the Galileo transformation, it's reduction to the one particle problem was carried out by Marsden–Weinstein method. The classification of reduced dynamic systems was given. For two of them the conditions of the global solution existence for dynamic equations with attractive potentials were found. The comparison of the structure of obtained Hamiltonians with integrals of one particle problem
with Bertrand's potentials was carried out.
