Let M be a dense o-minimal structure, N an unstable structure interpretable in M. Then there exists X , definable in N eq , such that X , with the induced N -structure, is linearly ordered and o-minimal with respect to that ordering. As a consequence we obtain a classification, along the lines of Zilber's trichotomy, of unstable þ-minimal types in structures interpretable in o-minimal theories.

BackgroundWhile o-minimality has been, for quite some time now, an important and fruitful subject in model theory (with applications in, for example, in real geometry), the A. Hasson's work was supported by the EPSRC grant no. EP C52800X 1.
