| Feb 8, 2021 at 23:46 | comment | added | Daniel Litt | I think K3 surfaces should be a counterexample to the original question (writing up something now). In general for smooth projective things K_0 is indeed generated by vector bundles, but it's definitely not so obvious (and it's false without smoothness)... | |
| Feb 8, 2021 at 23:29 | comment | added | Daniel Litt | @TimCampion: I'm not sure I understand your hint -- won't such resolutions be of infinite length in general? It seems to me one needs to allow more general vector bundles to get everything... | |
