Title: Equiangular lines in R^d.

Abstract: Suppose $0<\alpha<1$. The problem of determining the size of a
maximum set of lines (through the origin) in R^d s.t. the angle between
any two of them is arccos(\alpha) has been one of interest in
combinatorial geometry for a while now (since the mid 60s). Recently,
Yufei Zhao and some of his students settled this in a strong form. We will
see a proof of this result. The proof is a linear algebraic argument and
should be accessible to all grad students.
