直接代数闭域

Immediately algebraically closed fields

Peter Sinclair

摘要:

我们考虑两个重叠的领域,IAC和VAC,这是使用赋值论定义的,但不涉及一个独特的估值。相反,每个类都是由一个条件定义的,该条件量化了字段上所有可能的估值。在他的论文中,Hong询问这两个类是否相等(Hong,2013,问题5.6.8)。在本文中,我们给出了一个例子,否定回答洪的问题。我们还探讨了几种情况下,等价性不成立的一个额外的假设,包括情况下,每个$K'\equiv K$是IAC。

英文摘要:

We consider two overlapping classes of fields, IAC and VAC, which are defined using valuation theory but which do not involve a distinguished valuation. Rather, each class is defined by a condition that quantifies over all possible valuations on the field. In his thesis, Hong asked whether these two classes are equal (Hong, 2013, Question 5.6.8). In this paper, we give an example that negatively answers Hong's question. We also explore several situations in which the equivalence does hold with an additional assumption, including the case where every $K'\equiv K$ is IAC.
