Title: Feynman graphs to chord diagrams
|Affiliation:||University of Waterloo|
I will explain how classic techniques of algebraic combinatorics can, via chord diagrams, tell us about the leading log, next-to-leading log, etc, expansions in quantum field theory, and what we think chord diagrams can tell us about individual Feynman graphs as well.
Joint work with Julien Courtiel and with Kurusch Ebrahimi-Fard.
