取α是仿射Weyl群(A2n,S)两上某个满足α(S)=S的群自同构.仿射Weyl群(Cn,S)可以看做仿射Weyl群(A2n,S)在其群自同构α下的固定点集合.A2n上的长度函数l2n在Cn上的限制可以看做Cn上的某个权函数.本文给出了加权的Coxeter群(C3,l6)中所有左胞腔以及双边胞腔的清晰刻画并且证明(C3,l6)中的每个左胞腔都是左连通的.
Let α be a group automorphism of the affine Weyl group(A2n,S) with α(S)=S.Affine Weyl group(Cn,S) can be seen as the fixed point set of the affine Weyl group(A2n,S)under its group automorphism α.The restriction to Cn of the length function l2n on A2n can be seen as a weight function on Cn.In this paper,we give the description for all the left and two-sided cells of the specific weighted oxeter group(C3,l6) and prove that each left cell in(C3,l6) is left-connected.
