Целью работы является изучение влияния непустого края многообразия M на структуру глобальных аттракторов группы гомеоморфизмов G. Наш основной результат состоит в доказательстве того, что любой глобальный аттрактор A группы гомеоморфизмов G на многообразии M с непустым краем ∂M либо принадлежит краю и может быть как собственным подмножеством края, так и совпадать с краем, либо равен объединению края с глобальным аттрактором группы, индуцированной на внутренности многообразия M. Показано, что этим свойством неглобальные аттракторы, вообще говоря, не обладают. Построены примеры, иллюстрирующие содержание работы, включая пример с двумя различными глобальными аттракторами. </p></abstract><trans-abstract xml:lang="en"><p>Let G be the group of homeomorphisms of an n-dimensional topological manifold M with a nonempty boundary ∂M. The aim of this work is to study the effect of the nonempty boundary of the manifold M on the structure of global attractors of the homeomorphism group G. Our main result is the proof that any global attractor A of the homeomorphism group G on a manifold M with a nonempty boundary ∂M either belongs to the boundary and it can be either a proper subset of the boundary or coincide with the boundary, or it is equal to the union of the boundary with the global attractor of the group induced on the interior of the manifold M. It is shown that, generally speaking, non-global attractors do not possess this property. Various examples are constructed, including an example with two different global attractors. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>аттрактор</kwd><kwd>глобальный аттрактор</kwd><kwd>минимальное множество</kwd><kwd>группа гомеоморфизмов</kwd><kwd>многообразие с краем</kwd></kwd-group><kwd-group xml:lang="en"><kwd>attractor</kwd><kwd>global attractor</kwd><kwd>minimal set</kwd><kwd>group of homeomorphisms</kwd><kwd>manifold with boundary</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование осуществлено в рамках Программы фундаментальных исследований НИУ ВШЭ</funding-statement><funding-statement xml:lang="en">This work is an output of a research project implemented as part of the Basic Research Program at the National Research University Higher School of Economics (HSE University).</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">G.
