Abstract
We study superconducting fluctuation effects on the quasi-two-dimensional d–p model. We adopt the fluctuation exchange approximation in order to derive both normal and anomalous vertices of renormalized d-electron propagators, and then solve the Bethe–Salpeter equation and derive t-matrix as a superconducting fluctuation propagator. We calculate the normal d-electron self-energy self-consistently, and get self-consistent solutions in which the system is close to an antiferromagnetic instability.
