单一类型代数

Unityped algebras

Hebrew University(希伯来大学)

Boris Plotkin

AI总结:

本文引入了单一类型代数的概念,并证明其与逻辑几何等价性一致,推动了普遍代数几何与模型论的交叉研究。

摘要:

本文本质上是B.Plotkin和G.Zhitomirski在《St.Peterburg Math. J.》19卷第5期(2008年)发表的论文《Some logical invariants of algebras and logical relations between algebras》的延续。该论文的主要概念是代数的逻辑几何等价性(LG等价性)。这种代数等价性比初等等价性更严格。在本文中,我们引入了“单一类型代数”的概念,并将其与LG等价性联系起来。我们证明这两个概念是相同的。类型的概念是模型论中的核心思想之一。本文中引入的对应关系激发了一系列问题,将普遍代数几何与模型论连接起来。本文分为五个部分:1. 一般观点 2. 逻辑诺特性 3. 单一性与同构性 4. 逻辑完美代数 5. 代数逻辑中的一些事实。我们提供了新的总体观点,该观点出现在普遍代数几何的领域内,从而在模型论中应用了代数逻辑和普遍几何。

英文摘要:

The paper is essentially a continuation of B.Plotkin, G.Zhitomirski, "Some logical invariants of algebras and logical relations between algebras", St.Peterburg Math. J., {19:5}, (2008) 859 -- 879, whose main notion is that of logic-geometrical equivalence of algebras (LG-equivalence of algebras). This equivalence of algebras is more strict than elementary equivalence. In the paper we introduce the notion of unityped algebras and relate it to LG-equivalence. We show that these notions coincide. The idea of the type is one of the central ideas in M odel Theory. The correspondence introduced in the paper stimulates a bunch of problems which connect universal algebraic geometry and Model Theory. The paper consists of five sections: 1. General view 2. Logical noetherianity 3. Unitypeness and isomorphism 4. Logically perfect algebras 5. Some facts from algebraic logic. We provide a new general view on the subject, arising "on the territory" of universal algebraic geometry, which yield applications of algebraic logic and universal geometry in Model Theory.
