The Erdös-Falconer distance problem on the unit sphere in vector spaces over finite fields
arXiv:0809.4738
Abstract
art, Iosevich, Koh and Rudnev (2007) show, using Fourier analysis method, that the finite Erdös-Falconer distance conjecture holds for subsets of the unit sphere in $\mathbbm{F}_q^d$. In this note, we give a graph theoretic proof of this result.
