研究了临界级仿射Kac-Moody李代数上的模范畴与仿射标志方案G((T))/i上的D-模范畴之间的关系,其中i是Iwahori子群. 我们证明了一个本地化类型的结果,它在两边的某些子范畴之间建立了等价。 我们还建立了Kac-Moody模的某个子范畴与关于对偶群的Miura opers方案的拟凝聚层范畴之间的等价关系,从而证明了[FG2]的一个猜想。
We study the connection between the category of modules over the affine Kac-Moody Lie algebra at the critical level, and the category of D-modules on the affine flag scheme G((t))/I, where I is the Iwahori subgroup. We prove a localization-type result, which establishes an equivalence between certain subcategories on both sides. We also establish an equivalence between a certain subcategory of Kac-Moody modules, and the category of quasi-coherent sheaves on the scheme of Miura opers for the Langlands dual group, thereby proving a conjecture of [FG2].
