序域的完备性

Completeness of Ordered Fields

James Forsythe Hall

摘要:

这个项目的主要目标是证明阿基米得序域完备性的几个特征的等价性;其中一些出现在大多数现代文献中,作为实数的戴德金完备性定理,而一对夫妇则不为人所知,并与其他数学领域有关,如非标准分析。继续,我们研究非阿基米德领域的完整性,并提供了几个例子,这些领域的不同程度的属性,使用非标准分析,以产生一些相对"好"(特别是,他们是康托完成)的最终例子。作为一个小绕道,我们使用非标准分析的方法来简短地构造实数。

英文摘要:

The main goal of this project is to prove the equivalency of several characterizations of completeness of Archimedean ordered fields; some of which appear in most modern literature as theorems following from the Dedekind completeness of the real numbers, while a couple are not as well known and have to do with other areas of mathematics, such as nonstandard analysis. Continuing, we study the completeness of non-Archimedean fields, and provide several examples of such fields with varying degrees of properties, using nonstandard analysis to produce some relatively "nice" (in particular, they are Cantor complete) final examples. As a small detour, we present a short construction of the real numbers using methods from nonstandard analysis.
