具有方向跟踪性质的向量场

Vector Fields with the Oriented Shadowing Property

Sergei Yu. Pilyugin, Sergey Tikhomirov

摘要:

给出了光滑闭流形上具有定向跟踪性质的光滑向量场集合的$\Cone$ -内部($\Int^1(\OrientSh)$)的刻画。引入了一类结构不稳定的向量场的特殊类$\Bb$。证明了$\Int^1(\OrientSh\setminus\Bb)$集与结构稳定的向量场集一致。给出属于$\Int^1(\OrientSh)$的类$\Bb$的字段的示例。书目:18种。

英文摘要:

We give a description of the $\Cone$-interior ($\Int^1(\OrientSh)$) of the set of smooth vector fields on a smooth closed manifold that have the oriented shadowing property. A special class $\Bb$ of vector fields that are not structurally stable is introduced. It is shown that the set $\Int^1(\OrientSh\setminus\Bb)$ coincides with the set of structurally stable vector fields. An example of a field of the class $\Bb$ belonging to $\Int^1(\OrientSh)$ is given. Bibliography: 18 titles.
