  Transition to a nonrelativistic Pauli equation in Riemann space of constant
positive curvature for a Dirac particle in presence of the Coulomb field is
performed in the system of radial equations, exact solutions are constructed in
terms of Hein functions, the energy spectrum is derived. The same is done for
the Kepler quantum problem in hyperbolic Lobachevsky space, solutions are
constructed in terms of Hein functions, the energy spectrum is obtained.
