SUMMARY:Algebraic Combinatorics Seminar - Marcel Golz
CLASS:PUBLIC
DESCRIPTION:TITLE: Chord diagrams\, colours\, and QED\n\nSpeaker:\n Marcel
  Golz\n\nAffiliation:\n University of Waterloo\n\nZoom:\n Contact Karen Ye
 ats\n\nABSTRACT:\n\nFeynman graphs in quantum electrodynamics are essentia
 lly chord\ndiagrams with photon edges taking the role of chords attached t
 o lines\nor cycles given by electron edges. The associated Feynman integra
 ls\ninvolve traces of Dirac gamma matrices whose computation leads to\nlar
 ge sums of scalar Feynman integrals (cf. the earlier talk by O.\nSchnetz).
