      <abstract xml:lang="ru">
        <p>Предложим себе исследовать предельные случаи функции Риманна. Возьмем дифференциальное уравнение Р функции и рассмотрим функции (см. статью). По примеру Риманна мы представляем себе путь интегрирования в виде гибкой, растяжимой и легко подвижной нити. При своем движении особенная точка деформирует этот путь, толкая его перед собой и никогда не переступая его. При таком представлении пути интегрирования из замкнутых кривых соответствующих интегралам (11), (13), (15), для интегралов (16), (18), (20) получаем открытые пути в определенных направлениях простирающиеся в бесконечность.</p>

        <p>Let us investigate the limiting cases of the Riemann function. Let us take the differential equation P of the function and consider the functions (see article). Following Riemann's example, we imagine the path of integration in the form of a flexible, stretchable and easily movable thread. As it moves, the special point deforms this path, pushing it in front of itself and never crossing it. With this representation of the integration path from closed curves corresponding to integrals (11), (13), (15), for integrals (16), (18), (20) we obtain open paths in certain directions extending to infinity.</p>
