Abstract
Consideration was given to existence of simple invariant closed curves (simple contours) in the invariant m-connected compact sets with the interior of the phase plane for an arbitrary number m. The lower bound of the number of contours in these sets was established. Invariance and m-connectivity of the compact set with the interior was shown to be the sufficient condition for existence of at least m simple invariant contours in it.
