| Oct 12, 2014 at 23:28 | comment | added | Dan Ramras | My answer below is essentially a correction to the accepted answer, which seems to be saying that $\pi_n (\mathcal{F})$ is the unreduced complex K-theory of the sphere $S^n$. For $n=0$ this would give $\pi_0 (\mathcal{F}) = K(S^0) = \mathbb{Z} \oplus \mathbb{Z}$, in contradiction with the index theorem. (Maybe the issue is just notational, but I've never seen $K(X)$ used to mean reduced K-theory.) Is something wrong with my answer or my comments on the accepted answer? It would be nice to have a clear answer to the question. Maybe a tilde should just be added to Paul Siegel's answer? | |
