We consider the effective extended Hubbard Hamiltonian for the cuprates, with nearest-neighbor hopping which depends on the occupation. Using exact diagonalization in a 4 • 4 cluster, we obtain a large enhancement of d-wave pairing correlation functions for optimum doping. The physical picture is co

An effective Hamiltonian is developed for the d-d excitation model in the atomic limit. In a weak coupling approximation it is shown that the interaction between itinerant oxygen p holes mediated by virtual d -d excitations of Cu ++ may lead to superconductivity of purely electronic origin.
