Exact Solution of the Bogoluibov Hamiltonian for Weakly Imperfect Bose-Gas
(178K, LATeX)

ABSTRACT.   We show that the pressure for the Bogoluibov Weakly Imperfect Bose-Gas can
be calculated exactly in the thermodynamic limit.We point out sufficient 
and necessary conditions that it does not coincide with the pressure of the
Ideal Bose-Gas
