斜 brace 中的下中心列和上中心列的类似物:综述

Analogs of the lower and upper central series in skew braces: a survey

Cindy Tsang

AI总结:

本文综述斜 brace 的左列、右列等类似群下/上中心列的结构,证明其项间关系的新结果,探讨 Bonatto 和 Jedlička 定义的斜 brace 下中心列及 Ballester - Bolinches 等人提出的理想下中心列概念。

摘要:

斜 brace 是一种类环且类群的代数结构,最初在杨 - 巴克斯特方程的集合论解研究中被引入。本文综述了斜 brace 的左列、右列、基座列和零化子列,它们可视为群的下中心列和上中心列的类似物。除了关于这些列的一些已知事实外,我们还证明了关于其项之间关系的若干新结果。我们也考虑了由 Bonatto 和 Jedlička 定义的斜 brace 的下中心列,正如我们将解释的,它似乎是斜 brace 下中心列的“正确”类似物。对此,我们还讨论了由 Ballester - Bolinches 等人提出的理想的下中心列概念。

英文摘要:

A skew brace is a ring-like and group-like algebraic structure that was introduced in the study of set-theoretic solutions to the Yang-Baxter equation. In this survey paper, we shall consider the left series, right series, socle series, and annihilator series of skew braces. They may be regarded as analogs of the lower and upper central series of groups. Other than some well-known facts regarding these series, we shall prove several new results about the relationship among their terms. We shall also consider the lower central series of skew braces that was defined by Bonatto and Jedlička. As we shall explain, it seems to be the ``correct" analog of the lower central series for skew braces. Concerning this, we shall also discuss the notion of the lower central series of ideals that is due to Ballester-Bolinches et al.
