摘要 We study the space of positively expansive differentiable maps of a compact connected C ∞ Riemannian manifold without boundary. 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.
