On quadratic residue codes and hyperelliptic curves
arXiv:math/0609562
Abstract
A long standing problem has been to develop "good" binary linear codes to be used for error-correction. This paper investigates in some detail an attack on this problem using a connection between quadratic residue codes and hyperelliptic curves. One question which coding theory is used to attack is: Does there exist a c<2 such that, for all sufficiently large and all subsets S of GF(p), we have |X_S(GF(p))| < cp?
