Abstract
In this project we study nonperturbative aspects of gauge theories in thermodynamic equilibrium in the Matsubara-Fradkin formalism. We will study generalized quantum electrodynamics (GQED), the gauged Thirring model (GTM) and non-Abelian gauge theories, such as quantum chromodynamics (QCD). Our nonperturbative approaches are both the development and application of Fradkin's modified pertu…
