We prove the Gaussian dominance condition for the Huang–Yang–Luttinger model in the case with an arbitrary chemical potential. Using this condition in the framework of the method of correlation inequalities, we obtain two-sided bounds on the corresponding two-point thermodynamic means. Based on these bounds, we prove the existence of Bose condensation in this model.
