# INTERFACE FLUCTUATIONS IN NON EQUILIBRIUM STATIONARY STATES: THE SOS APPROXIMATION

Abstract : We study the 2d stationary fluctuations of the interface in the SOS approximation of the non equilibrium stationary state found in [4]. We prove that the interface fluctuations are of order $N^{1/4}$, N the size of the system. We also prove that the scaling limit is a stationary Ornstein-Uhlenbeck process.
