N2 - Two dimensional spin-fermion model is studied by using the perturbation method and the spin wave approximation. Non-crossing diagrams are calculated using the dominant pole approximation. As a result, we see that the renormalization parameter z is reduced as z ∝ L -1 4, where L is the linear dimension of the system, and the doped fermion becomes totally incoherent in the thermodynamic limit.
