The Specification Property for Flows from the Robust and Generic Viewpoint

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.
