SUMMARY:Algebraic Graph Theory - Yuval Widgerson
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: The limits of the inertia bound\n\nSPEAKER:\
 n Yuval Widgerson\n\nAFFILIATION:\n ETH Zürich\n\nLOCATION:\n Please cont
 act Sabrina Lato for Zoom link.\n\nABSTRACT: Spectral graph theory provi
 des us with a wide array of\nsurprising results which relate graph-theoret
 ic parameters to\nlinear-algebraic parameters of associated matrices. Amon
 g the most\nwell-known and useful of these is Hoffman’s ratio bound\, wh
 ich gives\nan upper bound on the independence number of a graph in terms o
 f its\neigenvalues.\n
