Summary: 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.
