设(W,S)是Coxeter系统,H是相应的不等参数Hecke代数.对于y,w ∈ W,s∈S的Laurent多项式My,ws和py,w在H的表示中起着重要的作用.本文研究了My,ws和py,w的性质,它们之间的关系,以及它们与W的左、右和双侧胞腔的关系。
Let (W,S) be a Coxeter system and H the associated Hecke algebra with unequal parameters. The Laurent polynomials My,wsand py,wfor y,w∈W and s∈S play an important role in the representations of H. We study the properties of My,wsand py,w, the relations among them, as well as with the left, right and two-sided cells of W.
