The exact fully closed (homogeneous) evolution equation for the equilibrium correlation function of S-particle operators for a system of N (N>S) spinless quantum particles has been derived, which shows the presence of subdynamics in the subspace of the S-particle subsystem, which interacts with the environment with the remaining N−S particles. This equation differs from the usual Nakamy–Zwanzig equation because it does not contain the unwanted inhomogeneous terms, which consist of all the interparticle correlations at the initial time moment.   Product Description popup.authors Ivanov Boris O.
