Expansive homeomorphisms of surfaces

  • Jorge Lewowicz


Letf be an expansive homeomorphism of a compact oriented surfaceM. We show thatS2 does not support such anf, and thatf is conjugate to an Anosov diffeomorphism ifM=T2, and to a pseudo-Anosov map ifM has genus ≥2. These results are consequences of our description of local stable (unstable) sets: everyxM has a local stable (unstable) set that consists of the union ofr arcs that meet only atx. For eachxMr=2, except for a finite number of points, wherer≥3.
