    "abstract": "The Hurwits transformation is generalized by introducing three new variables\ncalled \u0027extra\u0027. Interpretation of these extra variables allows us to establish\nrelation between isotropic harmonic oscillator and five-dimensional\nhydrogen-like atom in \u0027electromagnetic\u0027 fields of various configurations. For\nthe Schrodinger equations, the scheme of separation of extra variables is\nsuggested.",
