A foliated manifold M is not assumed to be compact. The chaotic foliations can be considered as multidimensional generalization of chaotic dynamical systems in the sense of Devaney. For foliations covered by fibrations we prove that a foliation is chaotic if and only if its global holonomy group is chaotic. We introduce the concept of the integrable Ehresmann connection for a foliation as a natural generalization of the integrable Ehresmann connection for smooth foliations. A description of the global structure of foliations with integrable Ehresmann connection and a criterion for the chaotic behavior of such foliations are obtained. Applying the method of suspension, a new countable family of pairwise nonisomorphic chaotic foliations of codimension two on 3-dimensional closed and nonclosed manifolds is constructed.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Мы называем слоение (M,F) на топологическом многообразии M хаотическим, если оно топологически транзитивно и объединение всех замкнутых слоев всюду плотно в M. При этом компактность слоеного многообразия не предполагается. Исследуемые нами топологические слоения можно рассматривать как многомерные обобщения хаотических динамических систем в смысле Дивани. Для топологических слоений (M,F), накрытых расслоениями, мы доказываем, что существование хаоса в (M,F) эквивалентно хаотичности его глобальной группы голономии. Мы вводим понятие интегрируемой связности Эресмана для топологических слоений как естественное обобщение интегрируемой связности Эресмана для гладких слоений. Получены описание глобальной структуры топологических слоений с интегрируемой связностью Эресмана и критерий хаотичности таких слоений. Применяя метод надстройки, нами построено новое счетное семейство хаотических, попарно не изоморфных топологических слоений коразмерности два на 3-мерных замкнутых и незамкнутых многообразиях.</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Жукова Н.И.
