Resumen:
We present a path-integral bosonization approach for systems out of equilibrium based on a duality transformation of the original Dirac fermion theory combined with the Schwinger?Keldysh time closed contour technique, to handle the non-equilibrium situation. The duality approach to bosonization that we present is valid for D>2 space?time dimensions leading for D = 2 to exact results. In this last case we present the bosonization rules for fermion currents, calculate current?current correlation functions and establish the connection between the fermionic and bosonic distribution functions in a generic,
