Hensel值域的相对可判定性和可定义性

Relative decidability and definability in henselian valued fields

Joseph Flenner

摘要:

设K是特征为0的Hensel值域。则K容许在每一片上有一个可定义的划分,其中一元一元多项式的首项可以作为线性映射的首项的可定义函数来计算。给出了两个应用:首先,一个建设性的量词消除相对于首项,建议一个相对的决策过程; 2第二,每个可定义的子集的K作为一个可定义的集合在首项进行线性平移的拉回表示。

英文摘要:

Let K be a henselian valued field of characteristic 0. Then K admits a definable partition on each piece of which the leading term of a polynomial in one variable can be computed as a definable function of the leading term of a linear map. Two applications are given: first, a constructive quantifier elimination relative to the leading terms, suggesting a relative decision procedure; second, a presentation of every definable subset of K as the pullback of a definable set in the leading terms subjected to a linear translation.
