AI总结:

针对特征0代数闭域上的连通约化群,本文结合经典群的组合计算与例外群的计算机验证,提出并证明了显著幂幺轨道的新不等式刻画,可服务于L-参数栈上尖点层的后续研究。

摘要:

本文证明了特征0代数闭域上连通约化群的显著幂幺轨道的一种新刻画。对于经典群,我们通过组合计算证明该刻画;对于例外群,则借助计算机进行检验。前两位署名作者在即将开展的关于L-参数栈上尖点层理论的工作中需要用到这一刻画。

英文摘要:

In this paper we prove a new characterization of the distinguished unipotent orbits of a connected reductive group over an algebraically closed field of characteristic 0. For classical groups we prove the characterization by a combinatorial computation, and for exceptional groups we check it with a computer. This characterization is needed in the theory of cuspidal sheaves on the stack of L-parameters in forthcoming work of the first two named authors.
