摘要：Relative t-designs and spherical designs are two important objects in algebraic combinatorics. In this talk, we first introduce the basic concepts and related facts concerning these two mathematical objects. Then we talk the relation between classical t-design and relative t-design in Johnson scheme. Finally, we present our work on Gaussian t-designs which is an Euclidean t-design.
