Robinson-Schensted-Knuth插入与A型对称群和Iwahori-Hecke代数的特征

Robinson-Schensted-Knuth insertion and characters of symmetric groups and Iwahori-Hecke algebras of type A

Arun Ram

摘要:

本文的目的是给出公式$$p_μ= \sum_{λ\vdash k} χ^λ(μ)s_λ,\formula$$的一个插入方案证明,其中$p_μ$是幂和对称函数,$s_λ$是Schur函数,$χ^λ(μ)$是对称群$S_k$的不可约特征标,它由划分$λ$索引,并在循环型置换$μ=(μ_1,\ldots,μ_\ell)$上求值.这个公式的证明是直接应用Robinson-Schensted-Knuth插入方案和Roichman最近的一个公式。

英文摘要:

The purpose of this note is to give an insertion scheme proof of the formula, $$p_μ= \sum_{λ\vdash k} χ^λ(μ)s_λ,\formula$$ where $p_μ$ is the power sum symmetric function, $s_λ$ is the Schur function and $χ^λ(μ)$ is the irreducible character of the symmetric group $S_k$ indexed by the partition $λ$ and evaluated at a permutation of cycle type $μ=(μ_1,\ldots,μ_\ell)$. The proof of this formula is by direct application of the Robinson-Schensted-Knuth insertion scheme and a recent formula of Roichman.
