Изучается вопрос о построении асимптотики решений указанных систем в критическом случае. Во второй части работы установлен факт существования критического многообразия для рассматриваемого класса систем и изучены основные его свойства. Рассмотрена задача построения асимптотики решений редуцированной на критическое многообразие системы. В качестве примера использования предложенного в работе метода асимптотического интегрирования строится асимптотика решений одного скалярного уравнения с запаздыванием.</p></abstract><trans-abstract xml:lang="en"><p>In this paper we study the asymptotic integration problem in the neighborhood of infinity for a certain class of linear functional differential systems. We construct the asymptotics for the solutions of the considered systems in a critical case. In the second part of the work we establish the existence of a critical manifold for the considered class of systems and study its main properties. We also investigate the asymptotic integration problem for a reduced system. We illustrate the proposed method with an example of constructing the asymptotics for the solutions of a certain scalar delay differential equation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>функционально-дифференциальные уравнения</kwd><kwd>критическое многообразие</kwd><kwd>асимптотическое интегрирование</kwd><kwd>метод усреднения</kwd><kwd>теорема Левинсона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>functional-differential equations</kwd><kwd>critical manifold</kwd><kwd>asymptotic integration</kwd><kwd>averaging method</kwd><kwd>Levinson’s theorem</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">грант Президента РФ</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">Беллман Р.
