| Aug 11, 2017 at 15:33 | comment | added | Antoine | What definition of dominant are you using here ? Is it $\Lambda^+$ (the $\mathbb{Z}^+$ span of the fundamental weights) or $\Lambda^+ - \rho$ ? | |
| Aug 3, 2017 at 11:13 | comment | added | Antoine | Thanks for the answer! You say the answer is different for singular blocks, can you say more about it (or give a reference)? | |

Though Kazhdan-Lusztig apparently didn't go into this, the non-integral case was later filled in by Soergel and generalized in the work of Kashiwara-Tanisaki for Kac-Moody Lie algebras. | |
