Jul 15, 2023 at 16:38 | comment | added | Andrey Ryabichev | @S.Carnahan it seems that the space $K_\pi(G,q)$ is defined just by the action $\rho$. on the other hand, k-invariants are defined only in situation when $\pi_1$ of base acts on all $\pi_n$ trivially. can you please give a more accurate link for the Sinh theorem? i cannot find it in the book | |

Sep 6, 2014 at 10:16 | comment | added | S. Carnahan♦ | I don't think such a space is uniquely characterized by the data you have given. For example, when $q=2$, the failure of strictness on $\rho_\ast$ is known (by a theorem of Sinh) to require a choice of "K-invariant" in $H^3(\pi,G)$ to specify the space $E$ up to homotopy equivalence. | |
Sep 6, 2014 at 7:36 | comment | added | Qiaochu Yuan | You need to be careful when you talk about the group of homeomorphisms from an object to itself which is only well-defined up to (weak) homotopy equivalence; $K(G, q)$ is a (weak) homotopy type, not a space. | |
