论文摘要
在本文中,我们构造了大约2美元的$ g $,明确的galois扩展名$ e/\ mathbb {q}(t)$ g $的$ g $带有$ e \ cap \ cap \ overline {\ mathbb {q}}} = \ mathbb {q} $。我们还提供了整数的明确算术进度$ t_0 $,以使专业化$ e_ {t_0}/\ mathbb {q} $的$ e/\ mathbb {q}(q}(q}(t)$ at $ t_0 $ at $ t_0 $具有Galois Group $ G $。
In this paper, we construct, for some $2$-groups $G$, explicit Galois extensions $E/\mathbb{Q}(T)$ of group $G$ with $E\cap\overline{\mathbb{Q}}=\mathbb{Q}$. We also provide explicit arithmetic progressions of integers $t_0$ such that the specialization $E_{t_0}/\mathbb{Q}$ of $E/\mathbb{Q}(T)$ at $t_0$ has Galois group $G$.
