| Mar 21, 2020 at 12:27 | comment | added | Pulcinella | @Ebz I think it's hard enough to come up with a natural example with $H^*(X)=V_\kappa(\mathfrak{g})$ as vector spaces, I am happy to worry about the extra structure later. | |

| Dec 28, 2019 at 22:44 | comment | added | user108998 | A couple queries. What is the grading u propose to put on the affine verma? also as an algebra isn't it a rather silly object, doesn't remember anything about the lie algebra except it's dimension for example. I think this question could use reforumlating so that the natural structures on the two sides match up better. Maybe u want to see the kac moody action or the vertex algebra structure motivically on X, like in the Grojnowski Nakajima picture | |
