不可判定性、单位群和$\mathbb{Q}$的某些全虚无限扩张

Undecidability, unit groups, and some totally imaginary infinite extensions of $\mathbb{Q}$

Caleb Springer

摘要:

我们产生新的例子,完全虚构的无限扩张的$\mathbb{Q}$有不可判定的一阶理论推广的方法由Martinez Ranero,Utreras和Videla为$\mathbb{Q}^{(2)}$。特别是,我们使用参数化家庭的多项式,其根是完全真实的单位申请最初开发的方法来证明的undecidability的全真实领域。这证明了$\mathbb{Q}^{(d)}_{ab}$对所有$d \geq 2$的不可判定性。

英文摘要:

We produce new examples of totally imaginary infinite extensions of $\mathbb{Q}$ which have undecidable first-order theory by generalizing the methods used by Martinez-Ranero, Utreras and Videla for $\mathbb{Q}^{(2)}$. In particular, we use parametrized families of polynomials whose roots are totally real units to apply methods originally developed to prove the undecidability of totally real fields. This proves the undecidability of $\mathbb{Q}^{(d)}_{ab}$ for all $d \geq 2$.
