LiMing, Haibo Chen, Liangbin Hu] The influence of repulsion and attraction in high-T c superconductors to the gap functions is studied. A systematic method is proposed to compute the gap functions using the irreducible representations of the point group. It is found that a pure s-wave superconductivity exists only at very low temperatures, and attractive potentials on the near shells significantly expand the gap functions and increase significantly the critical temperature of superconductivity. Astrong on-site repulsion drives the A 1g gap into a B 1g gap. It is expected that superconductivity with the A 1g symmetry reaches a high critical temperature due to the cooperation of the on-site and the next-nearest neighbor attractions.
