SUMMARY:Algebraic Graph Theory Seminar - Gordon Royle
CLASS:PUBLIC
DESCRIPTION:*Note different start time\n\nTITLE: Real Chromatic Roots of G
 raphs\n\nSpeaker:\n Gordon Royle\n\nAffiliation:\n The University of Weste
 rn Australia\n\nZoom:\n Contact Soffia Arnadottir\n\nABSTRACT:\n\nIn Febru
 ary 1988\, I arrived at C&O Waterloo for a postdoc with the\nlate Ron Read
 . He handed me a paper by Beraha\, Kahane and Weiss\, and\ntold me to appl
 y it to determining the location of the complex roots\nof chromatic polyno
 mials.  I’ve returned to the topic every few\nyears since then\, with v
 arying degrees of success---some positive\nresults\, but still many open p
 roblems and conjectures remain.
