On the structure of the directions not determined by a large affine point set

Combinatorics 2013-02-12 v1

Abstract

Given a point set UU in an nn-dimensional affine space of size qn1εq^{n-1}-\varepsilon, we obtain information on the structure of the set of directions that are not determined by UU, and we describe an application in the theory of partial ovoids of certain partial geometries.
