| Dec 13, 2010 at 18:04 | comment | added | Gianni Bello | Thanks a lot for the references. I think they may be very useful for me (at least to understand what can go wrong). You guessed right however, what I would need is exactly a jumping-like result for multiplier ideals. | |
| Dec 13, 2010 at 17:01 | comment | added | Karl Schwede | I suspect that this isn't true. If I think of an easy example, I'll tell you. You may want to look at some papers of Kevin Tucker and also of Howard Thompson and Karen Smith, for computing multiplier ideals / jumping numbers on surfaces. They look at questions of jumping (ie, when you have strict containment). If your question is false for surfaces, you should be able to counter-examples based on the combinatorics worked out there. | |
