讲座内容：

The purpose of "design theory" is to find good small subsets which approximate the given whole space. The space maybe good finite spaces (such as association schemes) or good topological spaces(such as spheres). This talk gives an overview on the study of design theoryfrom the viewpoint of algebraic combinatorics. We start with the survey ofvarious kinds of designs, such as combinatorial t-designs and more generallydesigns in association schemes, as well as spherical designs and theirgeneralizations. Our emphasis will be on the study of Fisher type lower boundsfor various designs and the existence and the classification problems of tightdesigns. At the end, I will discuss unitary t-designs and unitary t-groups.
