Many disordered random systems in applications can be described by N randomly coupled Ito stochastic differential equations in :
where is a sequence of independent copies of the one-dimensional Brownian motion W and ( is a sequence of independent copies of the ℝp-valued random vector ξ. We show that under suitable conditions on the functions b, σ, K and Φ the dynamical behaviour of this system in the N → (limit can be described by the non-linear stochastic differential equation
where P(t, dx dy) is the joint probability law of ξ and X(t).
