摘要:
我们在满足存在性公理的NSOP$_1$理论背景下发展了Kim-独立性理论。我们证明,在此类理论中,Kim-独立性具有传递性,并且$\ind^{K}$-Morley序列见证Kim-分叉。作为应用,我们证明在存在性假设下,于低度NSOP$_1$理论中,Shelah强类型与Lascar强类型重合;此外,我们引入了NSOP$_1$理论的一个秩概念。
英文摘要:
We develop the theory of Kim-independence in the context of NSOP$_{1}$ theories satsifying the existence axiom. We show that, in such theories, Kim-independence is transitive and that $\ind^{K}$-Morley sequences witness Kim-dividing. As applications, we show that, under the assumption of existence, in a low NSOP$_{1}$ theory, Shelah strong types and Lascar strong types coincide and, additionally, we introduce a notion of rank for NSOP$_{1}$ theories.
