| Mar 9, 2016 at 20:58 | comment | added | Dylan Wilson | The negative K groups are the easier part: $K^{-1}(\partial M)$ is just $K^0(\Sigma \partial M)$. The connecting homomorphism is just pulling back the bundle using the standard, geometric map $M/\partial M \rightarrow \Sigma \partial M$. (Build this by viewing $M/\partial M$ as collapsing a cone on $\partial M$ and just include into the `double cone' which is the suspension.) | |
