  We study the Gauged Thirring Model (also known as Kondo Model) in
thermodynamic equilibrium using the Matsubara-Fradkin-Nakanishi formalism. In
this formulation, both the temperature and the chemical potential are kept to
be nonvanishing. Starting from the field equations, we write down the
Dyson-Schwinger-Fradkin equations, the Ward-Fradkin-Takahashi identities, and
expressions for the thermodynamical generating functional. We find the
partition function of the theory and study some key features of its exact
two-point Green Functions, including the Landau-Khalatnikov/Fradkin
transformations and some limiting cases of interest as well. In particular, we
show that we can recover results from both the Schwinger and the Thirring's
models from the Kondo Model in thermodynamic equilibrium.
