Sep 29, 2015 at 12:40 | comment | added | NWMT | As for my cryptic comment about "most of these groups" I thought: "Take a subgroup H. It gets a hierarchy. At the bottom everything is free. We glue everything back quasiconvexly. Presto!" Mapping tori of free group automorphisms already give a counterexample. This Brady result is also interesting though, because it shows it's not just a free group thing. I'll look it up. | |
