  Quantum-mechanical wave equation for a particle with spin 1 is investigated
in presence of external magnetic field in spaces with non-Euclidean geometry
with constant positive curvature. Separation of the variable is performed;
differential equations in the variable r are solved in hypergeometric
functions. T he study o f z-dependence of the wave function has been reduced to
a system of three linked ordinary differential 2-nd order equations; till now
the system in z variable is not solved.
