Letbe an expansion of the ordered real additive group. Whenis o-minimal, it is known that eitherdefines an ordered field isomorphic toon some open subinterval, oris a reduct of an ordered vector space. We sayis field-type if it satisfies the former condition. In this paper, we prove a more general result for arbitrary expansions of. In particular, we show that for expansions that do not define dense-orders (we call these type A expansions), an appropriate version of Zilber’s principle holds. Among other things we conclude that in a type A expansion that is not field-type, every continuous definable functionis locally affine outside a nowhere dense set.
