Показаны условия совместности рассматриваемой неоднородной системы дифференциальных уравнений в частных производных и создан алгоритм построения нормальных решений в окрестности бесконечно удаленной точки. Доказана теорема о строении общего решения неоднородных систем дифференциальных уравнений в частных производных второго порядка и изучается «резонансная» система, возникающей, если частное решение соответствующей однородной системы совпадает в правой части неоднородный системы. На конкретном примере показано, как построить частное решение неоднородной системы дифференциальных уравнений в частных производных.</p></abstract><trans-abstract xml:lang="en"><p>The problem of constructing a normal solution to inhomogeneous systems of second-order partial differential equations using the Frobenus-Latysheva method in the neighborhood of an irregular singular point is considered. The compatibility conditions for the considered inhomogeneous system of partial differential equations are shown and an algorithm for constructing normal solutions in the vicinity of a point at infinity is created. A theorem on the structure of the general solution of inhomogeneous systems of second-order partial differential equations is proved and a “resonance” system is studied, which arises if the particular solution of the corresponding homogeneous system coincides on the right side of the inhomogeneous system. A specific example shows how to construct a particular solution to a non-homogeneous system of partial differential equations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неоднородная система</kwd><kwd>однородная система</kwd><kwd>нормальное решение</kwd><kwd>ранг</kwd><kwd>многочлен</kwd><kwd>аналитическая функция</kwd><kwd>ряд</kwd><kwd>иррегулярная особая точка</kwd><kwd>метод Фробенуса-Латышевой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inhomogeneous system</kwd><kwd>homogeneous system</kwd><kwd>normal solution</kwd><kwd>rank</kwd><kwd>polynomial</kwd><kwd>analytic function</kwd><kwd>series</kwd><kwd>irregular singular point</kwd><kwd>the Frobenius-Latysheva method</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Бұл зерттеуге Қазақстан Республикасы Ғылым және жоғары білім министрлігінің Ғылым комитеті қолдау көрсетті (Грант ИРН AP19675358).</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">Айнс Э.Л.
