Multiplicity matrices for the affine graded Hecke algebra

Dan Ciubotaru

摘要:

本文研究了通过计算Kazhdan-Lusztig型多项式来确定仿射分次Hecke代数的合成因子的问题。我们回顾了算法的\cite{L1,L2},并使用它们特别是计算,在每个真正的中心字符,承认回火模,几何参数化,Kazhdan-Lusztig多项式,合成列,和岩堀-松本对合的表示与岩堀固定向量的分裂$p$ -进群的类型$G_2$和$F_4$。

英文摘要:

In this paper, we look at the problem of determining the composition factors for the affine graded Hecke algebra via the computation of Kazhdan-Lusztig type polynomials. We review the algorithms of \cite{L1,L2}, and use them in particular to compute, at every real central character which admits tempered modules, the geometric parameterization, the Kazhdan-Lusztig polynomials, the composition series, and the Iwahori-Matsumoto involution for the representations with Iwahori fixed vectors of the split $p$-adic groups of type $G_2$ and $F_4$.
