论文摘要
令$ k $为$ \ mathbb {q} _2 $和$μ__{2^n} $ $ 2^n $ - unity的组的undmifififed扩展名,用于固定整数$ n \ geqslant 2 $。在本文中,我们使用$(φ,γ)$ - 模块的理论给出了$μ__{2^n} $的明确公式。
Let $K$ be an unramified extension of $\mathbb{Q}_2$ and $μ_{2^n}$ the group of $2^n$-th root of unity for a fixed integer $n\geqslant 2$. In this paper, we give an explicit formula for the $μ_{2^n}$-valued Hilbert symbol over $K_n := K(μ_{2^n})$ using the theory of $(φ, Γ)$-modules.
