The Boundness and Lowest Two-Sided Cell of Weighted Coxeter Groups of Rank 3
Journal of Lie theory, Tome 32 (2022) no. 2, pp. 499-518
We consider weighted Coxeter groups of rank 3 and its Hecke algebras in this paper. In this case, we show the boundness (in the sense of G. Lusztig) and the existence of a lowest two-sided cell c0. Then we describe c0 and the left cells in it. At last, we show that our conjectures P0--P15 hold for c0.
