Abstract
A new form of projector suggested in the previous paper of the series is applied to Time-Convolutionless Generalized Master Equations (TCL-GME) and the problem of spinless interacting electron gas with finite concentration. As a result, a closedlinear kinetic equation for the single-electron density matrix (Wigner distribution function) is obtained. In the second order in the short range interaction and after a short period of forgetting details of initial conditions, a new linear equation with time-independent coefficients results providing a linear alternative to the famous Boltzmann-Uehling-Uhlenbeck equation for quantum gases.
