DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MathPic/126/
 ">Equiangular lines and eigenvalue multiplicity</a>\nby Yufei Zhao (MIT) a
 s part of Mathematical Picture Language Seminar\n\nLecture held in Jeffers
 on 256 and Zoom https://harvard.zoom.us/j/779283357?pwd=MitXVm1pYUlJVzZqT3
 lwV2pCT1ZUQT09.\n\nAbstract\nEquiangular lines are configurations of lines
  in n-dimensional space\, all passing through the origin\, that pairwise m
 ake the same angle. Fix an angle\, in high dimensions\, what is the maximu
 m number of equiangular lines pairwise separated by the given angle? I wil
 l discuss the solution to this problem. A key step is in showing that a co
 nnected bounded degree graph has sublinear second eigenvalue multiplicity\
