报告内容:A fascinating topic of combinatorics is t-designs, which have a very long history. The incidence matrix of a t-design generates a linear code over GF(q) for any prime power q, which is called the linear code of the t-design over GF(q). On the other hand, some linear codes hold t-designs for some t ≥ 1. In this talk, we will study the linear codes of some t-designs held in the Reed-Muller and Simplex codes. Some general theory for the linear codes of t-designs held in linear codes and open problems will be presented.
