Query: Influence of Hole Doping on Antiferromagnetic Real-Space Approaches for
  the High-Tc Cuprates   Recently proposed scenarios for the cuprates make extensive use of a ``flat''
quasiparticle (q.p.) dispersion and short-range hole-hole interactions in
real-space, both caused by antiferromagnetic (AF) correlations. The density of
states (DOS) at half-filling has a robust peak which boosts the superconducting
critical temperature $T_c$ to large values as holes are introduced into the
(rigid) q.p. band. Here, the stability of such scenarios is studied after a
$finite$ but small hole density is introduced. The overall conclusion is that
the main features of real-space AF-based approaches remain qualitatively
similar, namely a large $T_c$ is found and superconductivity (SC) appears in
the ${\rm d_{x^2 - y^2}}$ channel. As the hole density grows the chemical
potential $\mu$ crosses a broad peak in the DOS. We also observe that extended
s-wave SC competes with d-wave in the overdoped regime.
