This is a lot more elementary than the corresponding you are talking about, but I would like to understand this categorification. | |
| Jan 24, 2011 at 17:08 | comment | added | Najdorf | Thanks for the answer and the pointers. Now here is what I am actually interested in (also why I asked the affine Grassmannian vs affine flag variety question earlier). What happens if one replaces the semi-simple Lie algebra with some arbitrary Kac-Moody algebra? Do nakajima's Quiver varieties still work in that context? Even if they you don't have the affine Grassmannian, because there is no preferred subset of simple roots like the one you have when you are dealing with an affine Kac-Moody algebra ... | |
