Здесь дано описание структуры неблуждающего множества непрерывных косых произведений, имеющих замкнутое множество периодических точек и таких, что множество (наименьших) периодов периодических точек, не ограничено. Построен пример дифференцируемого косого произведения с замкнутым множеством периодических точек, заданного на n-мерной клетке (n ≥ 3) и имеющего одномерное ω-предельное множество. </p></abstract><trans-abstract xml:lang="en"><p>The article continues the research of the asymptotic behavior of the trajectories of the most simple skew products on multidimensional cells conducted by the authors. Here we describe the structure of nonwandering set of continuous skew products having a closed set of periodic points and such that the set of (least) periods of periodic points is unbounded. An example of a differentiable skew product with a closed set of periodic points is constructed, defined on an n-dimensional cell (n ≥ 3) and having a one-dimensional ω-limit set.
