Examples of Non-isomorphic Prime Models
Abstract: It is a theorem due to Shelah that for L a countable language, T a stable theory, then if T has a prime model over a set A, it is unique. In this talk we describe two examples where this is not the case. In particular we describe an example of a stable theory in an uncountable language with non-isomorphic prime models, and an example of an unstable theory in a countable language with non-isomporphic prime models over a set A.
