| Apr 24, 2010 at 21:21 | comment | added | Tim Perutz | There are two ways of setting up obstruction theory - an abstract approach using Postnikov towers, and a more concrete one using cell complexes. The second method is the one that I find easier to remember and apply to manifolds. Hatcher covers the first approach nicely; for the second, I think I read Milnor-Stasheff and Steenrod's classic on fibre bundles. (Other MO-ers may have better suggestions...) | |

I am still slowly working my way through Hatcher's algebraic topology book; maybe what you mention is in there in a form I can't quite grasp yet? | |
