| Aug 19, 2011 at 19:17 | comment | added | Ian Agol | @Mustafa: I guess the argument I gave was incomplete. I think I've fixed it, adding some more exposition (an extra term in the Mayer-Vietoris sequence is needed). I think Ben Wieland's answer is simpler and probably easier to understand though. | |
