报告摘要：In this talk, we will present Euclidean (or Hermitian) self-orthogonal codes and determine their parameters by investigating the hulls of some primitive BCH codes. Several sufficient and necessary conditions for primitive BCH codes with large Hermitian hulls are developed by presenting lower and upper bounds on their designed distances. Furthermore, some Hermitian self-orthogonal codes are proposed via the hulls of BCH codes and their parameters are also investigated. We also present two sufficient and necessary conditions on designed distances such that the hull has the largest dimension.
