Дано обобщение на модель сингулярного осциллятора (СО) в одномерных геометриях Кэли – Клейна методом факторизации. Найдены спектр энергии и волновые функции стационарных состояний, имеющие кривизну пространства в качестве параметра. Для уровней энергии СО эффект ненулевой кривизны проявляется наглядным образом через положительное или отрицательное в зависимости от знака кривизны слагаемое квадратичное по номеру уровня. Полученные результаты совпадают с результатами, опубликованными ранее. Также показана в явном виде динамическая симметрия проблемы, которая реализуется в виде квадратичной алгебры Хана QH(3) или изоморфной ей алгебры Хиггса.</p></abstract><trans-abstract xml:lang="en"><p>The quantum-mechanical problem of a harmonic oscillator on a hyperbola as a one-dimensional space of constant negative curvature is considered in this article. A generalization to the singular oscillator model in the context of one-dimensional Cayley – Klein geometries is given by the factorization method. The energy spectrum and wave functions of stationary states are found having the curvature of space as a parameter. For the energy levels of the singular oscillator, the effect of non-zero curvature is clearly manifested through a positive or negative term, depending on the sign of the curvature, which is quadratic in the level number. The results obtained are consistent with those previously published. The dynamical symmetry of the problem is shown explicitly as a quadratic Hahn algebra QH(3) or its isomorphic Higgs algebra.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сингулярный осциллятор</kwd><kwd>пространство постоянной отрицательной кривизны</kwd><kwd>гипербола</kwd><kwd>алгебра Хана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the singular oscillator</kwd><kwd>the space of constant negative curvature</kwd><kwd>the hyperbola</kwd><kwd>a Hahn algebra</kwd><kwd>a Higgs alge- bra</kwd><kwd>Caley – Klein geometries</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">Genest, V.
