Aug 10, 2010 at 16:09 | comment | added | André Henriques | The long line is weakly contractible (all its homotopy groups are zero) but not contractible (there is no [0,1]-parametrized homotopy between the identity map and the zero map). | |

Aug 10, 2010 at 11:58 | comment | added | BS. | @ Henri : the long line isn't contractible. See en.wikipedia.org/wiki/Long_line_(topology) for a list of properties and some references. | |
Aug 10, 2010 at 9:21 | comment | added | Henri | Maybe there's something I don't get, but can't we assert that the line being contractible, any vector bundle on it must be trivial? | |
