Title: Introduction to the Polynomial Method in Combinatorics II (Lower
bounds on Kakeya sets over finite fields).
Abstract: For a finite field F, a Kakeya set is a subset of F^n that
contains a line in every direction. We will discuss a result of Dvir
showing a lower bound of C_n*q^n on the size of any Kakeya set over F^n,
where C_n only depends on n and F is a finite field of size q.
