SUMMARY:Algrbraic Graph Theory Seminar - Chris Godsil
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Constructing cospectral graphs with a diffe
 rent switching\n\nSpeaker:\n Chris Godsil\n\nAffiliation:\n University of 
 À¶Ý®ÊÓƵ\n\nRoom:\n MC 6486\n\nABSTRACT:\n\nMany years ago\, Brendan McKay
  and I introduced a construction of pairs\nof cospectral graphs\, sometime
 s known as local switching. In the same\npaper we introduced a second swi
 tching technique which produces\, as\nspecial cases\, the smallest pair of
  cospectral graphs and the smallest\npair of connected cospectral graphs.\
