We consider an o-minimal expansion M=(R,<,+,...) of a real closed field, and a real closed field S, complete in the sense of D. Scott, containing R as a dense subfield. We show that M has an elementary extension N=(S,<,+,...) with domain S. Moreover, such a structure N with domain S is unique.

Keywords: Real closed field; o-minimal structure

Domains: Logic [math.LO]
