Описывается эффективный метод, позволяющий находить любое эллиптическое решение автономного нелинейного обыкновенного дифференциального уравнения. Метод не требует интегрирования дополнительных дифференциальных уравнений. Большое внимание уделяется методике построения эллиптических решений с несколькими полюсами в параллелограмме периодов. С помощью данного метода найден явный вид всех эллиптических решений до четвертого порядка включительно для обыкновенного дифференциального уравнения, имеющего ряд физических приложений. Рассматриваемый метод допускает естественное обобщение на случай систем обыкновенных дифференциальных уравнений.</p></abstract><trans-abstract xml:lang="en"><p>The problem of constructing and classifying elliptic solutions of nonlinear differential equations is studied. An effective method enabling one to find an elliptic solution of an autonomous nonlinear ordinary differential equation is described. The method does not require integrating additional differential equations. Much attention is paid to the case of elliptic solutions with several poles inside a parallelogram of periods. With the help of the method we find elliptic solutions up to the fourth order inclusively of an ordinary differential equation with a number of physical applications. The method admits a natural generalization and can be used to find elliptic solutions satisfying systems of ordinary differential equations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мероморфные решения</kwd><kwd>эллиптические решения</kwd><kwd>автономные нелинейные дифференциальные уравнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>meromorphic solutions</kwd><kwd>elliptic solutions</kwd><kwd>autonomous nonlinear differential equations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский научный фонд</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kudryashov N.A.
