1801. Artem Chernikov, Byunghan Kim, Nicholas Ramsey Transitivity, lowness, and ranks in NSOP_1 theories E-mail: Submission date: 18 June 2020 Abstract: We develop the theory of Kim-independence in the context of NSOP_1 theories satisfying the existence axiom. We show that, in such theories, Kim-independence is transitive and that ↓^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.
