Abstract
We discuss the effects of quasiparticle energy dependence of the norma l density of states on the Eliashberg equations in the case of high-T- c superconductors and compare the numerical results with our recent tu nneling experimental data in Bi2Sr2CaCu2O8+x with T-c = 93 K. We also consider the possibility of quasiparticle energy dependence of the ele ctron-phonon spectral function alpha(2)(Omega)F(Omega) and calculate i ts effects on the superconducting density of states.
