幂零李群的特殊表示与流群的Poisson表示

Special representations of nilpotent Lie groups and the associated Poisson representations of current groups

A. M. Vershik, M. I. Graev

摘要:

在本文中,我们描述了一个新的模型的表示的电流群与一个半单李群的秩为1。在早期的论文70-80日(荒木,Gelfand-Graev-Vershik)提出了问题的不可约表示的当前组为$SL(2,R)$,并用于这一著名的福克空间结构,建设可以适用于任意局部紧群,是基于所谓的特殊表示的原组$G$,与非平凡1-上同调。利用幂零群的一维扩张(半直积)的特殊性质,给出了一种新的构造方法,该方法可以直接构造出群的特殊表示,然后利用作者以前的文章中的拟Poisson构造方法构造出当前群的表示.秩为1的半单群的抛物子群具有这样的半直积,它的特殊表示可以推广到整个半单群上。从而得到了所需的半单流群的不可约表示的新模型。

英文摘要:

In this paper we describe the new model of the representations of the current groups with a semisimple Lie group of the rank one. In the earlier papers of 70-80-th (Araki, Gelfand-Graev-Vershik) had posed the problem about irreducible representations of the current group for $SL(2,R)$, and was used for this the well-known Fock space-structure That construction could be applied to the arbitrary locally compact group,and is based on a so called special representation of the original group $G$, with nontrivial 1-cohomology. A new construction uses the special property of one dimensional extensions (semi-direct product)of the nilpotent groups which allows immediately to produce the special representation of the group and then to apply the quasi-Poisson construction from the previous papers by authors in order to construct the representation of current group. The parabolic subgroup of the semisimple Lie group of rank one has such semidirect product, and special representation of it can be extended onto whole semisimple group. As result we obtain needed new model of the irreducible representation of semi-simple current groups.
