An analysis of Dyson Schwinger equations using Hopf algebras

speaker: Dirk Kreimer (Institut des Hautes Etudes Scientifiques (IHES))

abstract: Hopf algebras are by their very definition uniquely suited to investigate recursive systems.

we apply them here to gain insight into the possible structure of solutions to untruncated Dyson--Schwinger equations for quantum electrodynamics and quantum chromodynamics.

We will emphasize number-theoretic aspects of the underlying skeleton expansion in this analysis.
