17. Sometimes it is argued that in real systems long-range Coulomb interaction of the charged particles should prevent phase separation. There are ways to circumvent this point [15]; here we concentrate our discussion on the model as given by equation (1).

21. Equation (3) implies that at most N/2 of the N states at each site can be occupied at one time.

25. The actual range of densities for which phase separation occurs has to be determined by a Maxwell construction; see [23].

27. An example for the shape of the Fermi surface for the uncorrelated system with inclusion of NNN hopping is given by Tohyama and Maekawa in [25], in which also the significance of the NNN hopping term is emphasized.
