半单李代数上的真仿射作用

群论 2016-05-13 v2

摘要

对于任何非紧半单实李群 GG,我们构造了其李代数 g\mathfrak{g} 上的一个仿射变换群,该群的线性部分在 AdG\operatorname{Ad} G 中是 Zariski 稠密的,并且是自由的、非阿贝尔的,且在 g\mathfrak{g} 上真不连续地作用。

备注

Section 3 of this paper draws heavily on the section 3 from my earlier paper arXiv:1303.3766 This is the version that appeared in Geometriae Dedicata. I have corrected some mistakes, added a few examples and added a proof that the Margulis invariant is well-defined
