Saddles for expansive flows with the pseudo orbits tracing property
Annales Polonici Mathematici 56 (1991), 37-48 DOI: 10.4064/ap-56-1-37-48
Let F be an expansive flow with the pseudo orbits tracing property on a compact metric space X. Suppose X is connected, locally connected and contains at least two distinct orbits. Then any point is a saddle.
