| Jun 2, 2011 at 21:57 | comment | added | Thomas Nevins | Hi Sandor, Thanks for the comment---if I'm not mistaken this is true for cyclic quotient singularities, no? [That's why I referred to your earlier MO answer that spells this out.] Though if not, then I'll correct my answer...in any case, again thanks for the clarification! | |

| Jun 2, 2011 at 7:30 | comment | added | Sándor Kovács | @Tom: for your last statement you also need the singularity to be $\mathbb Q$-factorial. Otherwise it might admit a small resolution in which case there are no discrepancies at all. | |
