В обеих геометрических моделях выведены дифференциальные уравнения второго порядка с шестью регулярными особыми точками, построены их точные решения фробениусовского типа. Для получения правила квантования для значений энергии используется известное условие, выделяющее трансцендентные решения Фробениуса. Это позволяет найти в явном виде спектры энергий, которые интерпретируются физически и похожи на спектры, возникающие из анализа скалярных уравнений Клейна–Фока–Гордона в этих пространственных моделях. Спектры с похожей структурой возникали ранее из анализа этих же систем уравнений на основе применения квазиклассического приближения.</p></abstract><trans-abstract xml:lang="en"><p>The known systems of the radial equations describing the hydrogen atom on the basis of the Dirac equation in the Lobachevsky–Riemann spaces of constant curvature are investigated. In the both geometrical models, the differential equations of second order with six regular singular points are found, and their exact solutions of Frobenius type are constructed. To produce the quantization rule for energy values we use the known condition which separates the transcendental Frobenius solutions. This provides us with the energy spectra that are physically interpretable and are similar to those for the Klein–Fock–Gordon particle in these space models. These spectra are similar to those that previously have appeared in studying the same systems of the equations with the use of the semi-classical approximation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дираковская частица</kwd><kwd>кулоновское поле</kwd><kwd>пространства постоянной кривизны</kwd><kwd>решения Фробениуса</kwd><kwd>условие трансцендентности</kwd><kwd>спектр энергии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Dirac particle</kwd><kwd>Coulomb field</kwd><kwd>spaces of constant curvature</kwd><kwd>Frobenius solutions</kwd><kwd>transcendency conditions</kwd><kwd>energy spectrum</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Schrodinger, E.
