Abstract:

We show that if $f$ is a homeomorphism of the 2-torus isotopic to the identity and its lift $\widetilde f$ is transitive, or even if it is transitive outside the lift of the elliptic islands, then $(0,0)$ is in the interior of the rotation set of $\widetilde f.$ This proves a particular case of Boyland’s conjecture.
