| Oct 27, 2013 at 21:19 | comment | added | Misha | To be more precise, one can ask if every purely pseudo anosov free subgroup is Schottky. Then it is an open problem. | |
| Oct 27, 2013 at 20:55 | comment | added | Lee Mosher | Your final paragraph is a bit vague. What does it mean to say that a free subgroup "arises from ping-pong"? Ping-pong is a particular construction for free subgroups that depends on choices of various qualitative and quantitative parameters; are you asking whether for a given free subgroup those choices and parameters can all be set so as to produce that particular subgroup? | |
