Abstract

We have investigated the critical behavior of the Hubbard model with attraction. To investigate the critical behavior of the model with repulsion, it is sufficient to use a unitary electron-hole transformation [3,8], and then the SCP correlation function will correspond to the spin-wave correlation function (the parameters of the models can be readily recalculated). The quasione-dimensional generalization of the investigated system can be used as a model of a high-temperature superconductor with "chemical" pairing mechanism [16,25].
