摘要：

The ground state of the extended Hubbard model is studied. The stability conditions for the antiferromagnetic, the charge density wave, and the superconducting state are analyzed in the same slave-boson representation, which is spin- and charge-rotationally invariant. It is found that at the concentration of electrons n0 = 1 the stable solutions are similar in form.
