Pathological examples of structures with o‐minimal open core
This paper answers several open questions around structures with o‐minimal open core. We construct an expansion of an o‐minimal structure R by a unary predicate such that its open core is a proper o‐minimal expansion of R. We give an example of a structure that has an o‐minimal open core and the exc...
