The exact expressions for the partition functions and occupation numbers of the model in the grand canonical, canonical, and microcanonical ensembles are found. From the calculations, it is followed that, oppositely to the accepted opinion that the chemical potential μ of an ideal Bose-gas is only negative, it can take values in the range −∞ &lt; μ &lt; ∞. The asymptotic expressions (in the case N ≫ 1) for the partition functions and occupation numbers for all above-mentioned thermodynamic ensembles are also evaluated.</p>}, number={4}, journal={Ukrainian Journal of Physics}, author={Bugrij, A.I. and Loktev, V.M.}, year={2022}, month={Jul.}, pages={235} }
