从鲁棒性和一般性观点看流的规范性质

The Specification Property for Flows from the Robust and Generic Viewpoint

Alexander Arbieto, Laura Senos, Tatiana Sodero

摘要:

证明了如果$X|_Λ$鲁棒地具有弱规范性质,其中$Λ$是孤立集,则$Λ$是双曲拓扑混合集,由此,如果$X$是闭流形$M$上鲁棒地具有弱规范性质的向量场,则流$X_t$是拓扑混合Anosov流.证明了存在一个剩余子集$\SR \in \Mundo$,使得如果$X \in \SR$和$X$具有弱规格性质,则$X_t$是Anosov流.

英文摘要:

We prove that if $X|_Λ$ has the weak specification property robustly, where $Λ$ is an isolated set, then $Λ$ is a hyperbolic topologically mixing set and, as a consequence, if $X$ is a vector field that has the weak specification property robustly on a closed manifold $M$, then the flow $X_t$ is a topologically mixing Anosov flow. Also we prove that there exists a residual subset $\SR \in \Mundo$ so that if $X \in \SR$ and $X$ has the weak specification property, then $X_t$ is an Anosov flow.
