Abstract:
We show that NSOP theories are exactly the theories in which Kim-independence satisfies a form of local character. In particular, we show that if is NSOP, , and is a type over , then the collection of elementary submodels of size over which does not Kim-fork is a club of and that this characterizes NSOP. - published version (14p)
