| Sep 8, 2017 at 2:03 | comment | added | Saal Hardali | @QiaochuYuan I have no idea, I asked this question too in the comments to an answer for a different question but the discussion was to long so I posted this question: mathoverflow.net/questions/243312/… | |
| Sep 8, 2017 at 2:03 | comment | added | Saal Hardali | @DylanWilson Since taking homotopy fixed points is a limit in the category of unpointed spaces I assume it could be the empty space couldn't it? | |
| Sep 8, 2017 at 0:52 | comment | added | Dylan Wilson | Also what do you mean by obstructing the 'existence' of homotopy fixed points? You said the group was acting on X so there's nothing in the way of taking homotopy fixed points for this action... | |
