Journal of Lie Theory 32 (2022), No. 2, 499--518 Copyright Heldermann Verlag 2022 The Boundness and Lowest Two-Sided Cell of Weighted Coxeter Groups of Rank 3 Jianwei Gao Beijing International Center for Mathematical Research, Peking University, P. R. China gaojianwei827@126.com 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. Keywords: Weighted Coxeter group, Hecke algebra, two-sided cell, left cell, A-function. MSC: 20C08, 20F55. [ Fulltext-pdf (167 KB)] for subscribers only. |
