关于Hecke代数特征标的组合公式

On combinatorial formulas for the characters of Hecke algebras

Matjaz Konvalinka

摘要:

Hecke代数是Coxeter群的漂亮q-扩张。本文证明了关于抛物子代数的特征的几个结果,重点讨论了抛物子代数的平凡表示和符号表示的特征。虽然大多数结果在类型A是已知的,我们的证明是一个组合的性质,并推广到(部分)结果在类型B和C。我们还提出了完整的描述,这样的字符类型I。

英文摘要:

Hecke algebras are beautiful q-extensions of Coxeter groups. In this paper, we prove several results on their characters, with an emphasis on characters induced from trivial and sign representations of parabolic subalgebras. While most of the results in type A are known, our proofs are of a combinatorial nature, and generalize to (partial) results in types B and C. We also present complete descriptions of such characters for type I.
