algebraic geometry 4 Kakeya sets

This lecture is part of an online algebraic geometry course, based on chapter I of "Algebraic geometry" by Hartshorne. It continues with more examples from algebraic geometry, in particular Kakeya sets over finite fields and the 27 lines on a cubic surface.

Topics in Combinatorics lecture 12.2 --- Dvir's solution to the finite-field Kakeya problem

A line in F_p^n is a set of the form {x+ty: t=0,1,...,p-1}. We call y the direction of the line. How small can a subset A of F_p^n be if it contains at least one line in every direction? This question can be regarded as a combinatorial version of the famous Kakeya problem (https://en.wikip

Unexpected Applications of Polynomials in Combinatorics - Larry Guth

Larry Guth Massachusetts Institute of Technology March 12, 2013 In 2007, Zeev Dvir shocked experts by giving a one-page proof of the finite field Kakeya problem. The new idea in the proof was to introduce high degree polynomials into a problem about points and lines. This idea has led to p
