A note on two of Hrushovski's constructions
In this paper we compare two of Hrushovski's constructions which arise in different contexts (Hrushovski, preprint [5], Hrushovski, 1989 [4]) and we show that under certain hypotheses they coincide. Using a group theoretic approach we also exhibit a structure which satisfies these hypotheses. (C) 2011 Elsevier B.V. All rights reserved.
