关于二维流形上流动的$C^r-$闭性

On $C^r-$closing for flows on 2-manifolds

Carlos Gutierrez

摘要:

对于集合的某个满测度子集B(即区间交换变换),满足如下条件:设X是紧致可定向曲面M上的$C^r$,$1\le r\le \infty$,向量场,具有多个奇点.给定X的一个非平凡回复点$p\in M$,p周围的完整映射半共轭到一个iet $E :[0,1) \to [0,1).$如果$E\in B$,则在$C^r-$拓扑中存在一个任意靠近X的$C^r$向量场Y,使得Y有一个通过p的闭轨线。

英文摘要:

For some full measure subset B of the set of iet's (i.e. interval exchange transformations) the following is satisfied: Let X be a $C^r$, $1\le r\le \infty$, vector field, with finitely many singularities, on a compact orientable surface M. Given a nontrivial recurrent point $p\in M$ of X, the holonomy map around p is semi-conjugate to an iet $E :[0,1) \to [0,1).$ If $E\in B$ then there exists a $C^r$ vector field Y, arbitrarily close to X, in the $C^r-$topology, such that Y has a closed trajectory passing through p.
