三维流形的拟Anosov同态

Quasi-Anosov diffeomorphisms of 3-manifolds

Todd Fisher, M Alejandra Rodriguez Hertz

摘要:

1969年,Hirsch提出了如下问题:给定一个双同态,和一个紧不变双曲集,描述它的拓扑和限制动力学。我们解决了双曲不变集是闭3-流形的问题:如果流形是可定向的,则它是环面与柄的连通和;否则它是环面与柄的连通和,并由对合表示.限制在这些流形上的仿射同态的动力学,称为拟Anosov仿射,也被分类为:它是DA-仿射同态的连通和,由交换对合表示。

英文摘要:

In 1969, Hirsch posed the following problem: given a diffeomorphism, and a compact invariant hyperbolic set, describe its topology and restricted dynamics. We solve the problem where the hyperbolic invariant set is a closed 3-manifold: if the manifold is orientable, then it is a connected sum of tori and handles; otherwise it is a connected sum of tori and handles quotiented by involutions. The dynamics of the diffeomorphisms restricted to these manifolds, called quasi-Anosov diffeomorphisms, is also classified: it is the connected sum of DA-diffeomorphisms, quotiented by commuting involutions.
