拟序环

Quasi-ordered Rings

Simon Müller

摘要:

拟序是一个二元的、自反的和传递的关系。在纯粹与应用代数杂志45(1987),S.M.法赫鲁丁介绍了概念(完全)准序域,并表明,每个这样的领域要么是一个序域或其他领域的价值。因此,拟序域非常适合于同时处理序域和值域。本文将证明同样的二分法对含1的交换环也成立。为此目的,我们首先发展一个适当的概念(完全)准序环。我们的证明二分法,然后利用Fakhruddin的结果,这是上面提到的。

英文摘要:

A quasi-order is a binary, reflexive and transitive relation. In the Journal of Pure and Applied Algebra 45 (1987), S.M. Fakhruddin introduced the notion of (totally) quasi-ordered fields and showed that each such field is either an ordered field or else a valued field. Hence, quasi-ordered fields are very well suited to treat ordered and valued fields simultaneously. In this note, we will prove that the same dichotomy holds for commutative rings with 1 as well. For that purpose we first develop an appropriate notion of (totally) quasi-ordered rings. Our proof of the dichotomy then exploits Fakhruddin's result that was mentioned above.
