格林函数与Glauberman度可除性

Green functions and Glauberman degree-divisibility

Meinolf Geck

摘要:

Glauberman对应是有限群特征标理论中的一个基本双射。在1994年,Hartley和Turull建立了一个度整除性质的字符相关的对应关系,受一个同余条件,这应该保持格林函数的有限群的李型,由德利涅和Lusztig定义。在这里,我们提出了一个一般性的论点,以完成证明的全等条件。因此,度整除性质具有完全的普遍性。

英文摘要:

The Glauberman correspondence is a fundamental bijection in the character theory of finite groups. In 1994, Hartley and Turull established a degree-divisibility property for characters related by that correspondence, subject to a congruence condition which should hold for the Green functions of finite groups of Lie type, as defined by Deligne and Lusztig. Here, we present a general argument for completing the proof of that congruence condition. Consequently, the degree-divisibility property holds in complete generality.
