DYNAMICS OF BOSE-EINSTEIN CONDENSATE WITH ACCOUNT OF PAIR CORRELATIONS

It is shown that for the system of Bose particles it can be obtained the chain of equations for the quasiaverages of the products of field operators, being similar to the Bogolyubov-Born-Green-Kirkwood-Yvon chain in the theory of classical gases. For the case when it is sufficient to confine ourselv...
