286. Philipp Hieronymi Expansions of subfields of the real field by a discrete set E-mail: Submission date: 6 January 2011. Abstract: Let K be a subfield of the real field, D be a closed and discrete subset of K and f : D^n -> K be a function such that f(D^n) is somewhere dense. Then (K,f) defines the set of integers. We present several applications of this result. We show that K expanded by predicates for different cyclic multiplicative subgroups defines the set of integers. Moreover, we prove that every definably complete expansion of a subfield of the real field satisfies an analogue of the Baire Category Theorem.
