Abstract: Equations for the evolution of the gauge independent analogue of the Wigner function are derived and applied to the description of a many charged particle system. The self-consistent field approximation is studied more closely. Possible applications of the formalism are illustrated by the calculations of dispersion relations for elementary excitations of fermion as well as boson systems. A possibility of application of the formalism in quantum optics is also investigated.
