| Nov 13, 2023 at 11:20 | comment | added | Bashar Saleh | I guess you are wondering whether the pullback is $𝐵(𝑓^{−1}𝐻')$ (and not $𝐵(𝑓^{−1}𝐻)$). The classifying space construction can be viewed as right adjoint (arxiv.org/pdf/1503.04840.pdf), but then it might be necessary to consider the homotopy pullback instead (I'm not sure). | |
