Рассмотрены некоторые задачи (осциллятор на орисфере, заряженная частица в аналоге постоянного однородного магнитного поля, определенного в вышеупомянутых системах координат), введение когерентных состояний, для решения которых является особенно адекватным методом.</p></abstract><trans-abstract xml:lang="en"><p>The separation of variables in the Laplace–Beltrami operator (Hamiltonian for a free quantum mechanical particle) of three-dimensional Lobachevsky space in the horospherical and quasi Cartesian coordinates provides an opportunity to introduce standard (conventional) coherent states. We consider problems, (oscillator, quantum mechanical particle in the uniform magnetic field) for which introduced coherent states are the adequate method of investigation.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Glauber R.
