极小对、极小域与隐常量域

Minimal pairs, minimal fields and implicit constant fields

Arpan Dutta

摘要:

最小定义对是由Alexandru,Popescu和Zaharescu为了研究剩余超越扩张而引入的。本文在值超越情形下得到了类似的结果。引入赋值超越扩张的极小定义域的概念,并证明了它们具有一些共同的分歧理论性质。研究了定义的极小域与隐式常量域之间的关系。进一步,我们研究了赋值超越扩张与伪柯西序列之间的关系。

英文摘要:

Minimal pairs of definition were introduced by Alexandru, Popescu and Zaharescu to study residue transcendental extensions. In this paper we obtain analogous results in the value transcendental case. We introduce the notion of minimal fields of definition for valuation transcendental extensions and show that they share some common ramification theoretic properties. The connection between minimal fields of definition and implicit constant fields is also investigated. Further, we explore the relationship between valuation transcendental extensions and pseudo-Cauchy sequences.
