Description
Superconductivity in copper oxide planes is calculated using the static Coulomb model. This model is based upon the attractive nature of the Fourier transform of the Coulomb interaction for wave vectors near aQ=π(±1,±1). Values of λ and Δ(k) are calculated at T=0 and also at Tc where the gap equation becomes a linear matrix equation. For some regions of parameter space values of λ are near unity. The gap Δ(k) is anisotropic
