摘要：

Effects of the backward scattering with large momentum transfer are examined in two-dimensional electron system with a special emphasis on electrons around (pi, 0), (0, pi). The phase diagram is shown in the plane of temperature T and hole doping delta in the mean field approximation and it is found that d-wave superconductivity, antiferromagnetism and pi-triplet pair can coexist near filling.
