对称群的Sylow分支系数

Sylow branching coefficients for symmetric groups

Eugenio Giannelli, Stacey Law

摘要:

设$p\ge 5$为素数,$n$为自然数。本文描述了对称群$\mathfrak{S}_n$的Sylow $p$ -子群的任意线性特征标$ϕ$的诱导特征标$ϕ\big\uparrow^{\mathfrak{S}_n}$的不可约成分,推广了作者早先的结果.通过这样做,我们引入了对称群的Sylow分支系数。

英文摘要:

Let $p\ge 5$ be a prime and let $n$ be a natural number. In this article we describe the irreducible constituents of the induced characters $ϕ\big\uparrow^{\mathfrak{S}_n}$ for arbitrary linear characters $ϕ$ of a Sylow $p$-subgroup of the symmetric group $\mathfrak{S}_n$, generalising earlier results of the authors. By doing so, we introduce Sylow branching coefficients for symmetric groups.
