Abstract

Let ff be a homeomorphism of the closed annulus AA that preserves orientation, boundary components and that has a lift f~\tilde f to the infinite strip A~\tilde A which is transitive. We show that, if the rotation number of both boundary components of AA is strictly positive, then there exists a closed nonempty connected set ΓA~\Gamma\subset\tilde A such that Γ],0]×[0,1]\Gamma\subset]-\infty,0]\times[0,1], Γ\Gamma is unlimited, the projection of Γ\Gamma to AA is dense, Γ(1,0)Γ\Gamma-(1,0)\subset\Gamma and f~(Γ)Γ.\tilde{f}(\Gamma)\subset \Gamma. Also, if p1p_1 is the projection in the first coordinate in A~\tilde A, then there exists d>0d>0 such that, for any z~Γ,\tilde z\in\Gamma, lim supnp1(f~n(z~))p1(z~)n<d.\limsup_{n\to\infty}\frac{p_1(\tilde f^n(\tilde z))-p_1(\tilde z)}{n}<-d. In particular, using a result of Franks, we show that the rotation set of any homeomorphism of the annulus that preserves orientation, boundary components, which has a transitive lift without fixed points in the boundary is an interval with 0 in its interior.
