UW-PIMS Colloquium: Yufei Zhao
- Date: 10/28/2022
- Time: 15:30
Lecturer(s):
Yufei Zhao, MIT
Location:
University of Washington
Topic:
Equiangular lines and eigenvalue multiplicities
Description:
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.
