SUMMARY:Joint Colloquium PMath+CO - Nick Olson-Harris
CLASS:PUBLIC
DESCRIPTION:TITLE: On the Theory of the Analytical Forms called Trees\n\nS
 peaker:\n Nick Olson-Harris\n\nAffiliation:\n University of Waterloo\n\nZo
 om:\n Contact Maxwell Levit\n\nABSTRACT:\n\nTrees are among the most funda
 mental of combinatorial structures.\nNowadays they appear all over mathema
 tics and computer science\, but\nthis has not always been the case. Trees 
 were first introduced\, at\nleast under that name\, in an 1857 paper of Ca
 yley by the same title as\nthis talk.
