Matroid Theory and Hrushovski's Predimension Construction

Logic 2011-05-20 v1 Combinatorics

Abstract

We give an exposition of some results from matroid theory which characterise the finite pregeometries arising from Hrushovski's predimension construction. As a corollary, we observe that a finite pregeometry which satisfies Hrushovski's flatness condition arises from a predimension.
