Remarks on unimodulatiry

Abstract

We clarify and correct some statements and results in the literature concerning unimodularity in the sense of Hrushovski [7], and measur- ability in the sense of Macpherson and Steinhorn [8], pointing out in particular that the two notions coincide for strongly minimal struc- tures and that another property from [7] is strictly weaker, as well as “completing” Elwes’ proof [5] that measurability implies 1-basedness for stable theories.
