报告摘要： Coding theory and t-designs have close connections and interesting interplay. In this talk, we will first introduce a class of ternary linear codes, which do not satisfy the conditions of the Assmus-Mattson theorem and do not admit 2-homogeneous automorphism groups, and prove that they still hold 2-designs. Then I will focus on a generalized Assmus-Mattson theorem, and try to explain the motivation and elementary idea behind the generalization. In addition, we will report some recent results in the constructions of near MDS codes holding t-designs and linear codes supporting 4-designs.
