Matroid Theory and Hrushovski's Predimension Construction
David M. Evans
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 observ…
Classification of some countable descendant-homogeneous digraphs
Daniela Amato, David M. Evans, John K. Truss
For finite q, we classify the countable, descendant-homogeneous digraphs in which the descendant set of any vertex is a q-valent tree. We also give conditions on a rooted digraph G…
The geometry of Hrushovski constructions, I. The uncollapsed case
David M. Evans, Marco S. Ferreira
An intermediate stage in Hrushovski's construction of flat strongly minimal structures in a relational language L produces omega-stable structures of rank omega. We analyze the pre…
The geometry of Hrushovski constructions, II. The strongly minimal case
David M. Evans, Marco S. Ferreira
We investigate the isomorphism types of combinatorial geometries arising from Hrushovski's flat strongly minimal structures and answer some questions from Hrushovski's original pap…
