Random perturbations of reaction-difiusion equations: the quasi de-terministic approximation

On considere des champs aleatoires u e (t,x)=(u 1 e (t,x),…,u n e (t,x)) definis comme les solutions d'un systeme d'equations aux derivees partielles ∂u k e /∂t=L k u k e +f k (x;u 1 e ,…,u n e )+eζ k (t,x). Les L k sont des operateurs elliptiques lineaires d'ordre 2, ζ k sont des champs gaussiens bruit blanc
