-Fold -Blocking Sets and -Minimal Codes
Hao Chen, Xu Pan, Conghui Xie
Blocking sets and minimal codes have been studied for many years in projective geometry and coding theory. In this paper, we provide a new lower bound on the size of -fold -b…

Self-dual codes and LCD codes in sum-rank metric
Qingfeng Xia, Hongwei Liu, Hao Chen +1
Sum-rank codes are an important class of codes which can be utilized for linear network coding, space-time coding and distributed storage. They can not only reduce the size of netw…

Optimal Few-GHW Linear Codes and Their Subcode Support Weight Distributions
Xu Pan, Hao Chen, Hongwei Liu +1
Few-weight codes have been constructed and studied for many years, since their fascinating relations to finite geometries, strongly regular graphs and Boolean functions. Simplex co…
