| Abstract: | In the present paper we study the dynamical properties of continuous maps on the Warsaw circle and show that for such a map a theorem similar to the Sarkovskii Theorem for interval maps holds, the closure of the set of periodic points coincides with the closure of the set of recurrent points, the depth of the center is not greater than 4, and the topological entropy is zero if and only if the periods of periodic points are the powers of 2. |
