We define a rich model to be one which contains a proper elementary substructure isomorphic to itself. Existence, non-structure, and categoricity theorems for rich models are proved. We show that a countable theory with few rich models is categorical in Ki. We also consider a stronger notion of richness, and in discussing it prove: "If T is an unstable theory, then for any saturated model M of ...

We investigate a notion called uniqueness in power κ that is akin to categoricity in power κ, but is based on the cardinality of the generating sets of models instead of on the cardinality of their universes. The notion is quite useful for formulating categoricity-like questions regarding powers below the cardinality of a theory. We prove, for (uncountable) universal theories T , that if T is κ...
