| Jan 31 at 6:40 | comment | added | ThorbenK | @RyanBudney I‘m aware of that. But for the context I have in mind, the fact that the map from cohomology of the topological group to the cohomology of the discrete group being zero is kind of the point. | |
| Jan 30 at 21:39 | comment | added | Ryan Budney | @KevinCasto I'm not asserting it solves the problem but it provides an enormous amount of insight. The question-asker does not make it clear he is aware, so I thought I would point out a result that gives structure. | |
| Jan 30 at 19:19 | comment | added | Kevin Casto | @RyanBudney just to be clear I don't think Milnor's paper solves this problem -- in the rat/real coeffs case he just focuses on showing that the map to group homology with the usual topology is zero in a range. | |
| Jan 30 at 19:05 | comment | added | Ryan Budney | You are aware of Milnor's theorem "On the homology of Lie groups made discrete"? | |
