SUMMARY:Tutte Colloquium - Paul Balduf
CLASS:PUBLIC
DESCRIPTION:TITLE: Graph theory and Feynman integrals\n\nSPEAKER:\n Paul B
 alduf\n\nAFFILIATION:\n University of Waterloo\n\nLOCATION:\n MC 5501\n\nA
 BSTRACT: Feynman integrals are one of the most versatile tools in\ntheore
 tical physics. They are used to compute perturbative solutions\nfor variou
 s interacting systems. Examples include scattering\namplitudes in quantum 
 field theory\, gravitational waves at black hole\nmergers\, and the scalin
 g behavior in statistical physics at critical\npoints. Every Feynman integ
 ral is defined in terms of a corresponding\nFeynman graph\, and besides th
 e concrete physical application\, it is\ninteresting to study the number t
 heory of Feynman integrals and how\nthey are related to combinatorial prop
 erties of the underlying graph.\nWhat can we know about the value of the i
 ntegral from examining the\ngraph alone? In particular: Under which condit
 ions will the Feynman\nintegrals of two non-isomorphic graphs evaluate to 
 the same number?
