Let f:X → X be a positively expansive map and let X be a compact connected metric space. Then f is topologically mixing and f has the pseudo-orbit-tracing property.

It is proved that (i) the C1-interior of the set of positively expansive differentiable maps coincides with the set of expanding maps, and (ii) Cl-generically, a differentiable map is positively expansive if and only if it is expanding.展开更多
