SUMMARY:Algebraic Graph Theory Seminar - Ferdinand Ihringer
CLASS:PUBLIC
DESCRIPTION:TITLE: Pseuodrandom Cliquefree Graphs\, Finite Geometry\, and 
 Spectra\n\nSpeaker:\n Ferdinand Ihringer\n\nAffiliation:\n Ghent Universit
 y\, Belgium\n\nZoom:\n Contact Soffia Arnadottir\n\nABSTRACT:\n\nA regular
  graph is called optimally pseudorandom if its second largest\neigenvalue 
 in absolute value is\, up to a constant factor\, as small as\npossible. De
 termining the largest degree of an optimally pseudorandom\ngraph without a
  clique of size s is a well-known open problem in\nextremal graph theory.
