设C是Coxeter群(W,S)中的单边或双边Kazhdan-Lusztig胞腔,Red(C)是所有w ∈ C的约化表达式的集合,被视为字母表S上的语言。卡塞尔曼已经证实红色(C)是有规律的。本文给出了W是双曲多边形所对应的群时胞腔的几何描述,并证明了我们的描述蕴含了卡塞尔曼的描述.
Let C be a one- or two-sided Kazhdan–Lusztig cell in a Coxeter group (W, S), and let Red(C) be the set of reduced expressions of all w ∈ C, regarded as a language over the alphabet S. Casselman has conjectured that Red(C) is regular. In this paper, we give a conjectural description of the cells when W is the group corresponding to a hyperbolic polygon, and show that our conjectures imply Casselman's.
