Abstract:

Abstract. We consider r interface model on a hard wall. The hydrodynamic large scale space-time limit for this model is discussed with periodic boundary by Funaki et al. (2000). This paper studies uctuations of the height variables around the hydrodynamic limit in equilibrium in one dimension imposing Dirichlet boundary conditions. The uctuation is nonGaussian when the macroscopic interface is attached to the wall, while it is asymptotically Gaussian when the macroscopic interface stays away from the wall. Our basic method is the penalization. Namely, we substitute in the dynamics the re ection at the wall by strong drift for the interface when it goes down beyond the wall and show the uctuation result for such massive r interface model. Then, this is applied to prove the uctuation for the r interface model on the wall. 1. Introduction and
