SUMMARY:Algebraic Graph Theory - Yuval Widgerson
CLASS:PUBLIC
DESCRIPTION:TITLE: The limits of the inertia bound\n\nSPEAKER:\n Yuval Widg
 erson\n\nAFFILIATION:\n ETH Zürich\n\nLOCATION:\n Please contact Sabrina
  Lato for Zoom link.\n\nABSTRACT: Spectral graph theory provides us with 
 a wide array of\nsurprising results which relate graph-theoretic parameter
 s to\nlinear-algebraic parameters of associated matrices. Among the most\n
 well-known and useful of these is Hoffman’s ratio bound\, which gives\na
 n upper bound on the independence number of a graph in terms of its\neigen
 values.
