Title: Existence over a predicate
Abstract: Joint project with Martin Bays and Pierre Simon.
Suppose that L contains a predicate symbol P and that T is some complete theory such that P is stably embedded. We give a sufficient condition that implies existence: any model of the induced theory T^P is the P part of a model T and give some examples where existence fails.
