| Oct 25, 2011 at 14:27 | comment | added | user5117 | Another comment: isn't Barkowski's result true in all dimensions because of BDPP (Mov is dual to the pseudoeffective cone) and BCHM (Fanos are Mori dream spaces)? | |
| Oct 25, 2011 at 12:12 | comment | added | J.C. Ottem | I've added his example in the answer below. I'd also be interested in hearing Artie's thoughts on this, so I hope he joins the discussion. | |
| Oct 25, 2011 at 11:35 | comment | added | Sándor Kovács | p.s: I didn't know about this example, but I was expecting Artie to answer the question. :) | |
| Oct 25, 2011 at 11:34 | comment | added | Sándor Kovács | @JC: yes, this would be an answer. Why don'y you put it as an answer? (In the mean time I realized that this is unfortunately not enough for my initial idea for that other question I started the question with) | |

| Oct 25, 2011 at 8:34 | comment | added | J.C. Ottem | By the way, Artie Prendergast-Smith has an example here arxiv.org/pdf/0910.5888 of a rational threefold whose nef cone is rational polyhedral but the effective movable cone is not. Would this be an answer to your question? | |
