| Jul 29, 2020 at 14:40 | comment | added | Neal | @HJRW That is why it is tangential to the conversation. :) | |
| Jul 29, 2020 at 11:05 | comment | added | HJRW | @Neal: I love that paper, but Stallings' approach is completely unrelated to the one proposed here (which, as Ben McKay points out, is morally very similar to Thurston's). | |

| Jul 27, 2020 at 20:28 | comment | added | Neal | Tangentially you might find Stallings' paper how not to prove the Poincare conjecture a useful read | |
| Jul 27, 2020 at 19:41 | comment | added | Paul Cusson | @MikeMiller Personally I don't know either, my knowledge of the subjects here is sparse. Perhaps this could lead to another question, can one find examples where "unconventional" properties of a manifold make it a Lie group? | |
| Jul 27, 2020 at 19:26 | comment | added | mme | I don't really know why you would imagine it would be any easier to construct a Lie group structure on a simply connected closed 3-manifold than finding a diffeomorphism to $S^3$ and pulling back the group structure by that diffeomorphism. How do you imagine simple connectedness help you? | |
