| Apr 29, 2010 at 15:48 | comment | added | Emerton | One fact that might help you is that all minimal projective resolutions have the same length, and that any proj. resolution can be truncated to the minimal length and remain projective. (And so any partial proj. res. of less than minimal length can be completed to a minimal proj. res.) | |
| Apr 29, 2010 at 14:15 | comment | added | Hailong Dao | The second one does not work because a reg sequence on N would not become a reg sequence on M (a regular element would, but not sequence in general). | |
| Apr 29, 2010 at 14:09 | comment | added | Erick Knight | I saw that. I am currently trying to understand the proofs that I have seen (in particular, why doesn't the second one work?). | |
| Apr 29, 2010 at 11:22 | comment | added | Kevin Buzzard | "Odd word choices are due to the French"---I would dispute that. I think that odd word choices are due to the fact that it has been badly translated ;-) Just because "plonge" looks a bit like "plunge" it doesn't mean it should be translated as "plunge" in this context! Similarly for "intervient" and "signifie". | |
