Ключевую роль при этом играет адаптация метода склеивания распределений, применявшегося ранее для симметрической группы. Сложность адаптации заключается в том, что с обобщением в случайном блуждании появляются две компоненты, к которым нужно применять склеивание, и эти компоненты влияют на обоюдное поведение. Для решения этой проблемы случайные блуждания разбиваются на несколько бло- ков, для каждого из которых даются отдельные оценки времени, необходимого для совпадения состояний. Доказаны оценки сверху и снизу на время перемешивания случайных блужданий на группах комплексных отражений, аналогичные оценкам Альдуса для симметрической группы.</p></abstract><trans-abstract xml:lang="en"><p>The subject of this paper is the mixing time of random walks on minimal Cayley graphs of complex reflection groups G(m,1,n). The key role in estimating it is played by the coupling of distributions, which has been used before for the same task on symmetric groups. The difficulty with its adaptation for the current case is that there are now two components in a walk, which are to be coupled, and they influence each other’s behaviour. To solve this problem, random walks are split into several blocks for each of which the time needed for their states to match is estimated separately. The result is upper and lower bounds on mixing times of random walks on complex reflection groups, analogous to those obtained by Aldous for a symmetric group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>случайные блуждания</kwd><kwd>графы Кэли</kwd><kwd>группы комплексных отражений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>random walks</kwd><kwd>Cayley graphs</kwd><kwd>complex reflection groups</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">Aldous, D.
