On the Kolyvagin formula for elliptic curves with good reductions over pseudolocal fields [PDF]

open access: yesМатематичні Студії, 2013
We consider the {relationships between the} local Artin map$heta colon K^* o mathrm{Gal}(K^{ab}/K)$ {and the} Hilbert symbol $(cdot,,cdot)colon K^*/K^{*m} imes K^*/K^{*m} longrightarrow mu_m$ for {a} general local field, as well as {between} the Tate ...

Canonical Sections of Artin–Schreier–Witt Extensions and an Algebraic Expression of the Reciprocity Map in Local Fields of Characteristic p

open access: yes
设 $K$ 为特征 $p$ 的局部域。对 $K$ 的 $p^e$ 阶全分歧循环扩张中局部互反映射的显式表达进行系统性研究。传统 Artin–Schreier–Witt 理论仅以隐式存在性方式给出扩域生成元,使得互反律的计算必须诉诸超越的微分残数算子,无法实现纯代数闭合。引入**规范截面算子** $\mathcal{L}$ 这一新工具,通过对 Witt 方程的解强制施加 Puiseux 级数常数项归零的典范约束,彻底消除了求根的多值歧义。在此基础上,建立并证明了**逐层AS解耦定理**,将高阶 Witt 方程的求解精确降维为有限步 $\mathbb{F}_p$-线性递推。证明了规范生成元与分歧滤波的严格匹配,并将 Galois 作用的读出转化为常数项提取的直接代数操作。证明了迹映射在 Artin ...
