本文确定了$\tB_{2}$和$\tG_{2}$型仿射Weyl群对任意参数的Kazhdan-Lusztig胞腔的划分.利用这些分区,我们表明,连续性猜想的Bonnaf\'e持有这些群体。
In this paper we determine the partition into Kazhdan-Lusztig cells of the affine Weyl groups of type $\tB_{2}$ and $\tG_{2}$ for any choice of parameters. Using these partitions we show that the semicontinuity conjecture of Bonnaf\'e holds for these groups.
