SUMMARY:Tutte Colloquium -Sophie Spirkl-Cliques and colouring in tournament
 s
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Sophie Spirkl\n\nAFFILIATION:\n University of Waterl
 oo\n\nLOCATION:\n MC 5501\n\nABSTRACT: A tournament is an orientation of 
 a complete graph\, and in\nterms of structural questions\, tournaments are
  often a natural\nanalogue of graphs. Neumann-Lara\, in 1982\, defined wha
 t it means to\ncolour a tournament. Only recently\, in 2023\, Aboulker\, A
 ubian\, Charbit\nand Lopes defined what the clique number of a tournament 
 is — but it\nis a bit more complicated than in graphs. What can we say a
 bout these\nparameters\, from a structural and computational point of view
 ? There\nare a few things to say\, including a recent joint result with Lo
 gan\nCrew\, Xinyue Fan\, Hidde Koerts\, and Ben Moore. \n\n[MANY OF YOU KN
 OW THE SEVERE CONSEQUENCES THAT A COVID INFECTION HAS\nHAD FOR MY FAMILY. 
 I WOULD CONSIDER IT A KINDNESS IF ATTENDEES WOULD\nWEAR MASKS. I WILL PROV
 IDE FREE MASKS FOR THOSE WHO MAY NEED THEM.]
