SUMMARY:Algebraic Graph Theory Seminar - Gabriel Coutinho
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Why are Hoffman's bounds for alpha and chi 
 truly duals of each\nother?\n\nSpeaker:\n Gabriel Coutinho\n\nAffiliation:
 \n Universidade Federal de Minas Gerais\, Brazil\n\nZoom:\n Contact Soffia
  Arnadottir\n\nABSTRACT:\n\nTwo of the most well known eigenvalue bounds f
 or graph parameters look\nsuspiciously related. Our goal in this talk is t
 o confirm this\nsuspicion by casting these bounds into a framework of semi
 definite\noptimization that will give us almost for free a duality relatio
 n. As\none should always expect in this context\, we will see a connection
  to\nthe Lovász theta function of a graph.\n
