To kinetics of polaron in the Bogolyubov reduced description method

On the basis of a generalization of the Chapman-Enskog method a new approach to derivation of hydrodynamic equations for weak density polaron gas has been elaborated taking into account the relaxation of temperature and velocity in the system. Non-locality of the collision integral of the used kinetic equation was taken into account also. Both circumstances lead to some modification of the standard transport theory.
