PIMS - UWashington Mathematics Colloquium: Yufei Zhao
Topic
Equiangular lines and eigenvalue multiplicities
Speakers
Details
Solving a longstanding problem on equiangular lines, we determine, for each given fixed angle and in all sufficiently large dimensions, the maximum number of lines pairwise separated by the given angle.
A key ingredient is a new result in spectral graph theory: the adjacency matrix of a connected bounded degree graph has sublinear second eigenvalue multiplicity.
My talk will discuss these problems and their connections.
