Abstract

Let f:T3T3f: \mathbb{T}^3\to\mathbb{T}^3 be a partially hyperbolic diffeomorphism on the 3-torus T3\mathbb{T}^3. In his thesis, Hammerlindl proved that for lifted center foliation Ffc\mathcal{F}^c_f, there exists R>0R>0, such that for any xR3x\in \mathbb{R}^3, Ffc(x)BR(x+Ec){\cal F}^c_f(x)\subset B_R (x+E^c), where R3=EsEcEu\mathbb{R}^3=E^s\oplus E^c\oplus E^u is the partially hyperbolic splitting of the linear model of ff. The same is true for the lifted center-stable and center-unstable foliations. Then he asked if the this property is true for strong stable and strong unstable foliations. In this note, we give a negative answer to Hammerlindl's question.
