N2 - Eliashberg equations with a pair coupling potential constructed from screened fermion-fermion interactions arising from the strong-correlation energy U are solved to obtain the superconducting gap, the quasiparticle density of states in the superconducting state, and the transition temperature as a function of the band parameters in strongly correlated electron materials. This analysis allows us to establish the conditions of the electronic structure for obtaining coupling and superconductivity in these materials.
