General expressions for the Baxter factor correlation functions are obtained in the mean spherical approximation for a mixture of hard ions of arbitrary size and charge in a dipolar solvent. A method for the calculation of the total correlation functions for the model considered is proposed.
Long-range (r ~ p ~-~ >> lattice spacing) spin-wave exchange produces a very strong pairing of the holes. Solutions of the BCStype equation for the superconducting gap A are found for various symmetries. The strongest pairing corresponds to d wave symmetry. The physical reasons for the strong pairin
