It is shown that the recently proposed finite size scaling renormalization group, when using systems infinite in one dimension and finite in the others, is equivalent to the Nightingale (correlation length) phenomenological renormalization. The equivalence, however, is concerned only with the critic

The quasiparticles around the Fermi level of the so-called d-p model are shown to behave as the mid-gap stat~ on the basis of the formal theory of Fermi liquid together with the Gutzwiller-type approximation for estimation of the chemical potential. On its basis, it is shown that the wavenumber-depe
