Abstract:
Here questions of preservation of properties at expanding countably categorical weakly o-minimal structures non-being 1-indiscernible by an arbitrary binary predicate are studied. A criterion for preserving the countable categoricity of a weakly o-minimal expansion of convexity rank 1 is obtained.
Keywords:
weak o-minimality, countable categoricity, expansion of models, equivalence-generating formula.
