Abstract: Green’s function theory of high Tc superconductor has been developed for two hole motion surrounded by spins in presence of antiferromagnetism and ferromagnetism generated by distorted spins due to hole motion. Some analytical results have been achieved using low temperature series expansion method for a two dimensional lattice and a half spin system. The gap parameter and the transition temperature have been derived. The effect of interaction parameter on transition temperature has been studied and the existence of S-symmetry, d-symmetry and symmetry breaking is discussed.
