The Finite Field Kakeya Problem

Combinatorics 2009-11-24 v1

Abstract

A Besicovitch set in AG(n,q) is a set of points containing a line in every direction. The Kakeya problem is to determine the minimal size of such a set. We solve the Kakeya problem in the plane, and substantially improve the known bounds for n greater than 4.
