Abstract:
We investigate a notion called uniqueness in power that is akin to categoricity in power , 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 , that if is -unique for one uncountable , then it is -unique for every uncountable ; in particular, it is categorical in powers greater than the cardinality of . - Version 1994-01-21_10 (22p) published version (25p)
