Topological entropy is one of such invariants. Studies about the topological entropy are concentrated on areas of homeomorphisms and one-dimensional continuous self-maps. In this note we consider Anosov maps, a sort of continuous maps on general compact metric spaces. By using a finite subshift and the largest positive eigenvalue we will calculate the topological entropy for Anosov maps.展开更多

It is proved that a strong mixing subshift of finite type has a chaotic set with full Hausdorff measure.展开更多

文摘We present a sufficient and necessary condition for the subshift of finite type to be a measure-preserving transformation or to be a strong mixing measure-preserving transformation with respect to the Hausdorff measure. It is proved that a strong mixing subshift of finite type has a chaotic set with full Hausdorff measure.
