Title: Null spherical $t$-designs
We introduce a new concept of "null spherical $t$-designs", and study Fisher type lower bounds for them. We will discuss the comparison between "null spherical $t$-designs" and "null combinatorial $t$-designs". Some open problems will be proposed.
This talk is independent with my previous talk on March 14 in our combinatorics seminar, and no prior knowledge of spherical designs or combinatorics will be necessary to follow this talk.
