摘要：

There is no Cooper pairing in the boson-fermion model (BFM) if bosons are not condensed. There is no Bose-Einstein condensation and, consequently, no Cooper pairing in two-dimensional BFM. The Cooper pairing is possible in a three-dimensional BFM if and only if bosons are condensed but can hardly be realized because of a charge-order instability.
