, depending on the site degree, under pair approximation and another dependence structure approximation. We point out improvements … the pair approximation to answer the question of the effects of the graph characteristics. We show how to improve the …-studied approximation is the mean field approximation. We explore in this paper the potentiality of a finer approximation: the pair …
