| Jan 29, 2013 at 14:59 | comment | added | Francesco Polizzi | @Artie: Thank you for the reference! Terminal 3-folds singularities are isolated cDV, hence rational. I'm espacially looking for results about ordinary singularities, but what you are pointing out is surely worth knowing. | |
| Jan 29, 2013 at 14:38 | comment | added | user5117 | Another data point: the answer to Question 1 is positive whenever X has only terminal singularities. A reference is Cutkosky, "Elementary contractions of Gorenstein threefolds." | |
