摘要：
A system of equations for the density matrix is derived to describe the condensate and quasi-particles of a weakly nonideal spatially homogeneous Bose gas. The equations are used to find the distribution function of the number of particles and the condensate coherence time. A numerical estimate is obtained for a temperature that is significantly lower than the transition temperature.
