| Abstract: | We discuss the wetting of the interface between two ordered phases by the disordered one in the Potts model withq large. We argue that a  low-temperature expansion can be used in this situation, with logq replacing . This model is analogous to the Blume-Capel model at low temperatures, which we use as an example to review the low-temperature expansions. |
