Cluster variation approximations for a contact process living on a graph

Peyrard, Nathalie; Franc, Alain - In: Physica A: Statistical Mechanics and its Applications 358 (2005) 2, pp. 575-592

, 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 …
