| May 12, 2011 at 21:33 | comment | added | Aaron Magid | So to clarify, the answer to my original question is negative. Homeo is not a deformation retract of HE because it isn't closed, but both deformation retract onto O(2) and both your answer and Agol above give fairly explicity ways of seeing this. Thanks to all for the help. | |
