| Mar 2, 2011 at 17:49 | comment | added | ACL | Liu: Unless there is something I missed in the proof, no H^1 is used here; only the fact that the dual of an ample line bundle has no sections. Am I wrong? | |
| Mar 2, 2011 at 13:35 | comment | added | Qing Liu | Note that Kodaira's vanishing theorem fails in positive characteristics (counterexamples are given by Mumford with normal surfaces and Raynaud with smooth surfaces). So this nice proof (and also that of J.C. Ottem) works only in characteristic 0. | |
