| Outline of Final Research Achievements |
In this research, we studied several random fields with long range correlations for mathematical analysis of phase separating interfaces and membranes. In particular, we considered the Δφ interface model and obtained the following results:
(1) We give an estimate on the probability that the field stays positive in low dimensions and its behaviors differ greatly from those of the higher dimensional case or other random interface models.(2) We show that in the case of two or more dimensions, once we impose weak pinning potentials the field is always localized in the sense that the corresponding free energy is always positive.
