| Feb 23, 2012 at 20:03 | comment | added | Sergei Ivanov | Applying ergodic theory here is problematic. Indeed Sinai's ergodicity implies that the set of trapped trajectories has zero measure. But unfortunately the set of trajectories in the question has zero measure itself (essentially, they all start from one point). | |
