由可定义子群诱导的可定义赋值

Definable Valuations Induced by Definable Subgroups

Katharina Dupont

摘要:

在他未出版的预印本“可定义的价值”柯尼希斯曼表明,每一个领域,承认一个t-亨泽尔拓扑是要么实封闭的或可分离封闭或承认一个可定义的价值,诱导t-亨泽尔拓扑。为了表明这一点柯尼格斯曼调查赋值环引起的某些(可定义)小组的领域。本文的目的是根据作者的博士论文,更详细地研究预印本中使用的方法,并根据Jahnke和Koenigsmann的论文纠正原始论文中的错误。

英文摘要:

In his unpublished preprint "Definable Valuations" Koenigsmann shows that every field that admits a t-henselian topology is either real closed or separably closed or admits a definable valuation inducing the t-henselian topology. To show this Koenigsmann investigates valuation rings induced by certain (definable) subgroups of the field. The aim of this paper, based on the authors PhD thesis, is to look at the methods used in the preprint in greater detail and correct a mistake in the original paper based on a paper of Jahnke and Koenigsmann.
