Abstract We have solved the Eliashberg gap equations which are valid for arbitrary phonon frequency, (Ωph), electron-phonon coupling constant, (λ), and screened Coulomb interaction, (μ *). We have used values of (Ωph),λ, and (μ *) appropriate to the cuprate superconductors, and calculated the density of states, the pair potential., and the value of the gap at T=0 K. Using the linearized Eliashberg equations in the matrix representation, we have calculatedT c and 2Δ/k T c . We have found that we can account for the highT c 's in the cuprates with reasonable values forλ, μ *, and Ωph.
