奇异Deligne-Langlands对应中的回火模

Tempered modules in exotic Deligne-Langlands correspondence

Dan Ciubotaru, Syu Kato

摘要:

本文的主要目的是在Kato意义下的奇异Deligne-Langlands对应下,对具有任意非单位根、不等参数的$C_n^{(1)}$型仿射Hecke代数确定调和模.我们的分类对调和Hecke代数模的外尔群模结构有几个应用。特别是,我们提供了一个几何和组合分类的离散系列,其中包含的符号表示的外尔群。这最后的组合分类是预期从工作的Heckman-Opdam和Slooten。

英文摘要:

The main purpose of this paper is to identify the tempered modules for the affine Hecke algebra of type $C_n^{(1)}$ with arbitrary, non-root of unity, unequal parameters, in the exotic Deligne-Langlands correspondence in the sense of Kato. Our classification has several applications to the Weyl group module structure of the tempered Hecke algebra modules. In particular, we provide a geometric and a combinatorial classification of discrete series which contain the sign representation of the Weyl group. This last combinatorial classification was expected from the work of Heckman-Opdam and Slooten.
