摘要

让 $C_n$, $Q_n$ 和 $D_n$ 是有序的环群、四元数群和二面体群 $n$,分别。的有限群代数的单位群结构 $2$-包含索引的正规循环子群的组 $2$ 已经研究过了。二面体基团 $D_{2n}, n\geq 3$ 广义四元数群 $Q_{4n}, n\geq 2$ 还包含一个正规循环子群的索引 $2$。有限群代数的单位群结构 $FQ_{12}$, $FD_{12}$, $F(C_2 \times Q_{12})$ 和 $F(C_2 \times D_{12})$ 在有限域上 $F$ 都是众所周知的。在本文中,我们继续这一研究并建立了群代数的单位群的结构 $F(C_n \times Q_{12})$ 和 $F(C_n \times D_{12})$ 在有限域上 $F$ 特征的 $p$ 包含 $p^k$ 元素。

Units in $F(C_n \times Q_{12})$ and $F(C_n \times D_{12})$
Let $C_n$, $Q_n$ and $D_n$ be the cyclic group, the quaternion group and the dihedral group of order $n$, respectively. Recently, the structures of the unit groups of the finite group algebras of $2$-groups that contain a normal cyclic subgroup of index $2$ have been studied. The dihedral groups $D_{2n}, n\geq 3$ and the generalized quaternion groups $Q_{4n}, n\geq 2$ also contain a normal cyclic subgroup of index $2$. The structures of the unit groups of the finite group algebras $FQ_{12}$, $FD_{12}$, $F(C_2 \times Q_{12})$ and $F(C_2 \times D_{12})$ over a finite field $F$ are well known. In this article, we continue this investigation and establish the structures of the unit groups of the group algebras $F(C_n \times Q_{12})$ and $F(C_n \times D_{12})$ over a finite field $F$ of characteristic $p$ containing $p^k$ elements.
