约化p-adic群的酉等价

Unitary equivalences for reductive p-adic groups

Dan Barbasch, Dan Ciubotaru

摘要:

在类型论的框架下,我们建立了约化p-adic群的光滑表示范畴的Bernstein分支到相应的Hecke代数的酉性的转移,只要Hecke代数是具有几何参数的仿射Hecke代数,在Lusztig意义下(可能由根数据的自同构群扩展).众所周知,有一大类这样的例子(在论文中详细介绍)。因此,我们在内窥镜检查的精神下,建立了不同群体之间的整体性联系。

英文摘要:

We establish a transfer of unitarity for a Bernstein component of the category of smooth representations of a reductive p-adic group to the associated Hecke algebra, in the framework of the theory of types, whenever the Hecke algebra is an affine Hecke algebra with geometric parameters, in the sense of Lusztig (possibly extended by a group of automorphisms of the root datum). It is known that there is a large class of such examples (detailed in the paper). As a consequence, we establish relations between the unitary duals of different groups, in the spirit of endoscopy.
