Sažetak
We discuss results for two types of spectral functions, the function A(k,
omega) of interacting fermions on a square lattice, and the function
alpha(2)F(k, k", omega) of the square lattice electrons interacting with
phonons. Strong local Coulomb interactions lead to enhanced momentum
dependence of alpha(2)F(k, k", omega) which may increase the
superconducting transition temperature T-c. Finally, the Eliashberg
equations have been solved for the isotropic case; however, the use of the
Fermi-surface-averaged spectral weight, alpha(2)(omega)F(omega), might be
inappropriate in the case of high-temperature superconductors.
