Feb 17, 2011 at 16:40 | comment | added | Wanderer | It's about nonsingular varieties... I need the singular case as well! :) | |
Feb 17, 2011 at 16:39 | comment | added | J.C. Ottem | There is a lot of literature on this out there. Try for example Zak's article mathecon.cemi.rssi.ru/zak/files/… | |

Feb 17, 2011 at 16:31 | comment | added | Wanderer | Is this true also for singular varieties? I know about the bounds in Hartshorne, but the result there (Theorem 6.6.4) is for non-singular curves in P^3. | |
Feb 17, 2011 at 16:25 | comment | added | J.C. Ottem | Yes, this is called the castelnuovo bound. For curves you'll find it in Hartshorne. In this case, g is bounded by a simple quadratic polynomial in the degree, and I think there are higher-dimensonal analogues as well. | |
