SUMMARY:Algebraic Graph Theory Seminar - David Roberson
CLASS:PUBLIC
DESCRIPTION:TITLE: What do graph planarity and homomorphism counts have to
  do\nwith quantum mechanics?\n\nSpeaker:\n David Roberson\n\nAffiliation:\
 n Technical University of Denmark\n\nZoom:\n Contact Soffia Arnadottir\n\n
 ABSTRACT:\n\nI will introduce the notion of quantum isomorphisms of graphs
 . These\nare defined in terms of a game in which two cooperating players\n
 attempt to convince a referee that two given graphs are isomorphic.
