Rigidity for partially hyperbolic diffeomorphisms

Abstract: In this work we completely classify C ∞ conjugacy for conservative partially hyperbolic diffeomorphisms homotopic to a linear Anosov automorphism on the 3-torus by its center foliation behavior. We prove that the uniform version of absolute continuity for the center foliation is the natural hypothesis to obtain C ∞ conjugacy to its linear Anosov automorphism. On a recent work Avila, Viana and Wilkinson proved that for a perturbation in the volume preserving case of the time-one map of an Anosov flow absolute c… Show more

“…For perturbations of the linear Anosov map, the same result may also be obtained by using the first theorem in [SY19] once it is shown that the exponents of the Anosov diffeomorphism and its linear part are the same, which can be deduced from quasi-isometry of the foliations. A different approach to prove smooth conjugacy to a linear Anosov model was developed in [Var18] that uses smoothness of the center foliation plus extra requirements about the stable/unstable holonomies; to apply that approach one may have to establish that the hypotheses of our main theorem imply the requirements of [Var18], which does not seem to be direct. Another result related to the case that |λ c | = 1 is the one proved in [AVW15]: any partially hyperbolic diffeomorphism (that preserves a Liouville probability measure) close to the time-one map of a geodesic flow of a negatively curved surface with a smooth center foliation is the time-one map of a flow (close to the geodesic flow).…”

“…We may see the opposite of atomic disintegration when the conditional measures are equivalent to Lebesgue measures. This may also give important consequences for the dynamics ( [3,24,23] and references therein). It turns out that in dynamics it is not unusual to obtain either atomic or some "higher" regular disintegration (meaning for instance equivalent to Lebesgue) in many contexts ( [21,3,18,9]).…”
