a typo corrected

| Sep 4, 2011 at 16:45 | comment | added | R W | Sorry - that's my typo. Of course, I wanted to say that the Poincare recurrence theorem is valid for any action with an INVARIANT measure. I've corrected my answer. | |
| Sep 4, 2011 at 14:29 | comment | added | Pengfei | Thank you for the reference! What do you mean for a measure being quasi-invariant? Poincare recurrence theorem requires more than preserving the measure class (take the north-south map on S^2 for example). | |
