| Feb 12, 2010 at 4:39 | comment | added | David Ben-Zvi | Matthew - lack of perfection of the unit certainly makes life harder, but I think you have to roll with whatever you're given.. eg the same problem holds for BG_m or BG in characteristic zero. | |
| Feb 10, 2010 at 22:00 | comment | added | Laurent F. | You may find what you're looking for in this article by C.Noot-Huyghe: smf4.emath.fr/Publications/Bulletin/137/html/… but the sheaf of differential operators involved is Berthelot sheaf of overconvergent p-adic differential operators. She proves G/B is D-affine for this sheaf of diff. operators. | |

| Feb 10, 2010 at 18:23 | comment | added | Emerton | As a general comment (which you should certainly feel free to ignore!) is that the sheaf of full differetial operators is not such a good one to work with. (Just as one example, if I remember correctly, the structure sheaf O_X on a smooth variety is not represented by a perfect complex of D-modules.) | |
