We find the Kahler spaces with conic singularity, where the oscillator and Coulomb systems on three-dimensional sphere and two-sheet hyperboloid are originated. Then we construct the superintegrable oscillator system on three-dimensional sphere and hyperboloid, coupled to monopole, and find their four-dimensional origins. In the latter case the metric of configuration space is non-Kahler one. Finally, we extend these results to the family of Kahler spaces with conic singularities.To the memory of Professor Valery Ter-Antonyan, 11 pagesHigh Energy Physics - TheoryMathematical PhysicsExactly Solvable and Integrable SystemsQuantum Physicstext
