设G是定义在p-ady域上的En型分裂代数群。这个群包含一个对偶对G×G‘,其中一个群是G2类型的。当限制到对偶对时,G的最小表示给出了对偶对中两个群的表示的对应关系。当作用于极小表示时,我们证明了G和G‘的球面Hecke代数的匹配。这意味着,对于球面表示,在Arthur和Langland的意义上,对应是函数式的。
Let G be a split algebraic group of type E n defined over a p-adic field. This group contains a dual pair G× G′ where one of the groups is of type G 2. The minimal representation of G, when restricted to the dual pair, gives a correspondence of representations of the two groups in the dual pair. We prove a matching of spherical Hecke algebras of G and G′, when acting on the minimal representation. This implies that the correspondence is functorial, in the sense of Arthur and Langlands, for spherical representations.
