Abstract:

仿射~Weyl~群\,$(\widetilde{C}_4,\,S)$\,可被看成仿射\,Weyl\,群\,$(\widetilde{A}_7,\,\widetilde{S})$~在某个群自同构\,$\alpha$\,下的不动点集合.记\,$\widetilde{l}:\widetilde{A}_7\longrightarrow\mathbf{\mathbf{N}}$\,是仿射\,Weyl\,群\,$\widetilde{A}_7$\,上的长度函数.则\,$\widetilde{l}$\,在\,$\widetilde{C}_4$\,上的限制为\,$\widetilde{C}_4$\,的权函数记作\,$L$.本文给出带权\,Coxeter\,群\,$(\widetilde{C}_4,\,L)$\,的胞腔分解.
