DESCRIPTION:MEENAKSHI MCNAMARA\, PERIMETER INSTITUTE FOR THEORETICAL PHYSIC
 S\n\nExact quantum chromatic numbers of Hadamard graphs and products\n\nQu
 antum chromatic numbers are defined in terms of non-local games on\ngraphs
 . This talk gives a proof of the exact quantum chromatic number\nof Hadama
 rd graphs using a conjugacy class graphs approach. This\nfurther allows us
  to consider graph products\, and we compute the exact\nquantum chromatic 
 number of the categorical product of Hadamard\ngraphs. This work makes use
  of several results for the quantum\nchromatic numbers of quantum graphs\,
  an operator algebraic\ngeneralizations of graphs. In particular\, we also
  discuss results on\nproducts of quantum graphs from joint work with Rolan
 do de Santiago.\n\nMC 5417
