При некоторых дополнительных условиях доказано, что предельный гомеоморфизм - отображение с ограниченным (1,σ)-весовым (q,p)-искажением. Более того, получено свойство полунепрерывности снизу характеристик искажения гомеоморфизмов.</p></abstract><trans-abstract xml:lang="en"><p>In this paper we study the locally uniform convergence of homeomorphisms with bounded (1,σ)-weighted (q,p)-distortion to a limit homeomorphism. Under some additional conditions we prove that the limit homeomorphism is a mapping with bounded (1,σ)-weighted (q,p)-distortion. Moreover, we obtain the property of lower semicontinuity of distortion characteristics of homeomorphisms.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полунепрерывность снизу</kwd><kwd>гомеоморфизм с ограниченным (1</kwd><kwd>\sigma )-весовым (q</kwd><kwd>p)-искажением</kwd><kwd>группа Карно</kwd></kwd-group><kwd-group xml:lang="en"><kwd>semicontinuity from below</kwd><kwd>homeomorphism with bounded (1</kwd><kwd>σ)-weighted (q</kwd><kwd>p)-distortion</kwd><kwd>Carnot group</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Решетняк Ю.Г.
