| May 16, 2012 at 5:23 | comment | added | Tyler Lawson | The symmetric groups have complicated cohomology taken individually, but taken all together the homology possesses extra structure (Dyer-Lashof operations) that makes it simple to describe. A nice reference, if I remember correctly, is Bisson and Joyal's "Q-rings and the homology of the symmetric groups." (preprint here: hopf.math.purdue.edu/Bisson-Joyal/Luminy.pdf) | |

| May 15, 2012 at 23:03 | comment | added | Theo Johnson-Freyd | I believe that "I'm interested in the homotopy groups of the free simplicial commutative ring on Let $X_\bullet$ be a simplicial set" should probably be "I'm interested in the homotopy groups of the free simplicial commutative ring on A SIMPLICIAL SET. Let $X_\bullet$ be a simplicial set". Is this correct? | |
| May 15, 2012 at 19:15 | comment | added | John Wiltshire-Gordon | I think some computations of higher homotopy groups of spheres can be rephrased as the derived functors of symmetric powers: arxiv.org/abs/1103.4580v1 | |
