| Feb 5, 2011 at 8:07 | comment | added | Pete L. Clark | @Hailong: I agree with you. Since I hadn't upvoted your question, I can only conclude that I never really read it. (That has now been remedied on both accounts.) But two different questions with the same answer is fine with me (I have given essentially the same answer to many questions...). | |

| Feb 5, 2011 at 5:25 | comment | added | Hailong Dao | Dear Pete, I asked a very close question here: mathoverflow.net/questions/27424/…. I think the answers there which are regular (for example, Mohan Kumar's answer) also answer your question, since any stably free ideal is free, see Eisenbud "Commutative Algebra...", Lemma 19.18. | |

| Feb 5, 2011 at 1:01 | comment | added | Pete L. Clark | @Manny: thanks very much for your comment. As far as I'm concerned, it's informative enough to be worthy of leaving as answer. (Note that Corollary 4.5 answers my P.S. even more squarely than the theorem. It also suggests that I guessed wrong at what "finitely many primes minimal above zero" means.) | |
| Feb 4, 2011 at 22:15 | comment | added | Manny Reyes | I don't think you'll find any non-finitely generated examples; see Theorem 4.3 of projecteuclid.org/DPubS/Repository/1.0/… | |
