Cambanis, Stamatis (ed.) et al., Stochastic processes: a Festschrift in honour of Gopinath Kallianpur. New York: Springer-Verlag. 329-336 (1993).
M. Z. Guo, G. C. Papanicolaou and S. R. S. Varadhan [Commun. Math. Phys. 118, No. 1, 31-59 (1988; Zbl 0652.60107)] established a hydrodynamic scaling limit for the non-gradient version of the Ginzburg-Landau type model. For the same model, the author shows that starting from an initial distribution that is locally Gibbsian, at any later time the distributions remain close to locally Gibbsian distributions.
