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.
