Abstract
We study the effect of site diagonal disorder on the pairing amplitude by a perturbation method. Using an extended Hubbard model with the intersite at traction we analyze fluctuations of order parameter in the presence of non- magnetic disorder and discuss the instability of various solutions with p-w ave pairing.
