В ходе исследования подробно анализируются уравнения Чэфи-Инфанте с быстро осциллирующими членами и диссипацией. В модель вводится+ малый параметр, и в зависимости от его предельных значений формулируется усредненная (предельная) задача. Доказывается, что траекторные аттракторы исходного уравнения сходятся к аттракторам усредненного уравнения, и формулируется соответствующая теорема. Кроме того, показано, что при условиях единственности решений имеет место сходимость глобальных аттракторов, что достигается при наложении дополнительных условий на нелинейные члены. В работе также изучаются сингулярные задачи с нетривиальными граничными условиями в перфорированных областях и на границах их полостей. В этом случае получаемое усредненное (предельное) уравнение имеет иную структуру по сравнению с исходным. Оно отражает эффективные средние характеристики модели и может включать дополнительный потенциальный член. Доказано, что при стремлении малого параметра к нулю аттракторы сходятся в смысле Хаусдорфа. В качестве основного результата описаны усредненные аттракторы и показано, что аттракторы исходной системы стремятся к аттракторам предельного уравнения. В данной работе впервые рассматривается задача усреднения уравнений Чафе–Инфанте в периодически перфорированной среде, обосновываются научная новизна и актуальность полученных результатов. Данное исследование вносит вклад в развитие методов теории усреднения дифференциальных операторов и может найти применение при изучении решений нелинейных дифференциальных уравнений.</p></abstract><trans-abstract xml:lang="en"><p>This work addresses the averaging problem for the Chafee–Infante equation in a micro-heterogeneous medium. It analyzes the equation with rapidly oscillating terms and dissipation. The model introduces a small parameter and formulates an averaged problem based on its limits. The study proves that the trajectory attractors of the original equation converge to those of the averaged equation. It establishes the relevant theorem. In cases with unique solutions, it investigates the convergence of global attractors, adding further conditions on the nonlinear terms. The work also analyzes singular problems with nontrivial boundary conditions in perforated domains and on cavity boundaries. Here, the averaged equation differs from the original, reflecting the model’s effective averaged characteristics and possibly an extra potential term. As the small parameter approaches zero, the study shows that the attractors converge in Hausdorff distance. The main result is that the attractors of the original Chafee– Infante equation converge to those of the averaged (limit) equation as the small parameter approaches zero. This work establishes this convergence for the first time in the context of homogenization in a periodically perforated medium, highlighting the scientific novelty and relevance of the findings. This research advances averaging methods for differential operators and may apply to solutions of nonlinear differential equations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уравнения Чафе–Инфанте</kwd><kwd>пористая среда</kwd><kwd>аттракторы</kwd><kwd>перфорированная область</kwd><kwd>усреднение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chafee-Infante equations</kwd><kwd>porous medium</kwd><kwd>attractors</kwd><kwd>perforated domain</kwd><kwd>homogenization</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Бұл зерттеуді Қазақстан Республикасы Ғылым және жоғары білім министрлігінің Ғылым комитеті (Грант №AP22684340) қаржыландырады.
