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.
