| Jan 11, 2010 at 13:59 | comment | added | Saul Glasman | Unless I'm wrong, K_0 is in general neither left nor right exact, and so it doesn't make sense to talk about its derived functors. But at least in topological K-theory, and the K-theory of C*-algebras, the K_0 and K_1 groups fit into an exact hexagon. | |
