Abstract:
The method of collective variables is used to investigate the properties of a nonideal Bose
system near absolute zero temperature. It is shown that the method developed previously
by the author for constructing correlation functions enables one to extend the method of
collective variables to systems with hard core interaction. The time dependence of the
correlation functions is investigated for large and small values of the time $t$.
