具有正体积的(部分)双曲集的拓扑结构

Topological structure of (partially) hyperbolic sets with positive volume

Jose F. Alves, Vilton Pinheiro

摘要:

我们考虑了黎曼流形中吸引正体积点集的双曲集和部分双曲集。对于可微性大于1的复同态,我们得到了关于这类集合的拓扑结构的几个结果。我们特别表明,有没有部分双曲马蹄正体积这样的双同态。我们还给出了属于具有正体积的双曲集或部分双曲集的几乎所有点的极限集的刻划。

英文摘要:

We consider both hyperbolic sets and partially hyperbolic sets attracting a set of points with positive volume in a Riemannian manifold. We obtain several results on the topological structure of such sets for diffeomorphisms whose differentiability is bigger than one. We show in particular that there are no partially hyperbolic horseshoes with positive volume for such diffeomorphisms. We also give a description of the limit set of almost every point belonging to a hyperbolic set or a partially hyperbolic set with positive volume.
