Research Abstract

The main topic of this research is the analysis for the large scale and long time asymptotic behavior of the effective interface model. First results of this research is the large deviation for the interface model with a conservation law. The next is the characterization for the family of stationary measures for the stochastic dynamics with non-convex potential, and the description of the partial differential equation from scaling limit of the stochastic dynamics.
