摘要
让 G 是一个分裂于(\mathbb R\ )的连通还原群。我们证明,G 的完全非负单元中的每个单能元在某些 Levi 子群中都是正则的,这证实了卢茨蒂希的一个猜想。
Regularity of Unipotent Elements in Total Positivity
Let G be a connected reductive group split over \(\mathbb R\). We show that every unipotent element in the totally nonnegative monoid of G is regular in some Levi subgroups, confirming a conjecture of Lusztig.
