Perturbative solution of the schwinger model

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

One interesting question for the exactly solvable Schwinger model is how to infer the exact solution from perturbation theory. We give a systematic procedure of deriving the exact solution from Feynman diagrams of arbitrary order for arbitraryn-point functions. As a byproduct, we derive from perturbation theory exact integral equations that then-point functions have to obey.
