| Mar 8, 2010 at 0:35 | comment | added | algori | Somnath -- I think there is a potential problem when you want to take the $(n+5)$ skeleton of the pullback of $P$. $P$ does not come equipped with a preferred CW-structure. Ok, let us assume that there is a way to pick one so that $P\to K(\mathbf{Z},3)$ is a locally trivial fibration (this seems plausible but has to be proven), but then, depending on which one we pick, the skeleta of the pullback of $P$ may or may not be fibered locally trivially over $M$. | |
