设G是一个约化群.几何Satake等价实现了Langlands对偶群在原群G的仿射格拉斯曼GrG = G((t))/G[[t]]上用球面反常层(或D-模)表示的范畴。在本文中,我们执行的第一步,在实现的范畴表示的量子群对应的GrG的几何。这个建筑的想法属于雅各布·卢里。
Abstract.Let G be a reductive group. The geometric Satake equivalence realized the category of representations of the Langlands dual group Ğ in terms of spherical perverse sheaves (or D-modules) on the affine Grassmannian GrG = G((t))/G[[t]] of the original group G. In the present paper we perform a first step in realizing the category of representations of the quantum group corresponding to Ğ in terms of the geometry of GrG. The idea of the construction belongs to Jacob Lurie.
