A viewpoint on amalgamation classes

Comment.Math.Univ.Carolin. 51,4 (2010) 681-691.

Abstract:We give a self-contained introduction to universal homogeneous models (also known as rich models) in a general context where the notion of morphism is taken as primitive. We produce an example of an amalgamation class where each connected component has a saturated rich model but the theory of the rich models is not model-complete.

Keywords: model theory, universal homogeneous model, model companion, amalgamation class
