Abstract:
New examples of transitive cylindrical cascades with discrete orbits (the Besicovitch property) are constructed. For each γ∈(0,1)γ∈(0,1) there exists a cylindrical cascade over a rotation of the circle, with a γ-Hölder continuous function, that has the Besicovitch property; furthermore, the Hausdorff dimension of the set of points on the circle which have discrete orbits is at least 1−γ. This improves (by ε) an earlier estimate. In addition, an example of a cascade with discrete orbits such that the corresponding function satisfies the Hölder condition with each exponent γ∈(0,1) is constructed.
