1 Desiderata for this page
Ideally this page will also include at least the following information:
- A reference, probably to Baues' book, for obstructions to null-homotopy.
- A precise reference to [Kervaire1959].
- A precise reference to Bott who also proved Theorem 2.1 (perhaps even before Kervaire?)
- Conventions/constructions for settling the sign in Theorem 2.1.
- A reference to Husemoller's Fibre Bundles for a similar result for Chern classes. This also gives an explanation of the result via the Chern character which should be included in the page.
- Further discussion about the same problem for other characteristic classes and other bases spaces.
