关于^2F_4(q)的交叉特征表示对真子群的限制

On the restriction of cross characteristic representations of ^2F_4(q) to proper subgroups

Frank Himstedt, Hung Ngoc Nguyen, Pham Huu Tiep

摘要:

证明了Ree群$^2F_{4}(q), q=2^{2n+1}\geq8$的奇特征的任意非平凡表示对任意真子群的限制是可约的.我们还确定了所有三元组$(K, V, H)$,使得$K \in \{^2F_4(2), ^2F_4(2)'\}$,$H$是$K$的真子群,$V$是$K$的奇特征表示,且绝对不可约地限制为$H$ .

英文摘要:

We prove that the restriction of any nontrivial representation of the Ree groups $^2F_{4}(q), q=2^{2n+1}\geq8$ in odd characteristic to any proper subgroup is reducible. We also determine all triples $(K, V, H)$ such that $K \in \{^2F_4(2), ^2F_4(2)'\}$, $H$ is a proper subgroup of $K$, and $V$ is a representation of $K$ in odd characteristic restricting absolutely irreducibly to $H$.
