有序阿贝尔群中的远距性

Distality in Ordered Abelian Groups

University of Tsukuba(筑波大学)

Koki Okura

AI总结:

本文研究了有序阿贝尔群的远距性特征,通过赋予素数p的赋值s_p,证明了远距性与肋大小的有界性之间的关系,并扩展了先前的有限脊准则。

摘要:

我们提供了有序阿贝尔群远距性的特征化:一个有序阿贝尔群是远距的当且仅当对于每个素数p,相对于“赋值”s_p的肋的大小是均匀有界的。这扩展了Aschenbrenner、Chernikov、Gehret和Ziegler为具有有限脊的有序阿贝尔群提供的远距性准则。

英文摘要:

We provide a characterization of distal ordered abelian groups: An ordered abelian group is distal if and only if, for each prime number $p$, the sizes of ribs with respect to the "valuation" $\mathfrak{s}_p$ are uniformly bounded. This generalizes the distality criterion for ordered abelian groups with finite spines given by Aschenbrenner, Chernikov, Gehret, and Ziegler. Furthermore, we prove that every ordered abelian group has a distal expansion, affirmatively answering a conjecture posed by the same authors.
