2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/102306The probabilistic study of effective interface models has been quite active in recent years, with a particular emphasis on the effect of various external potentials (wall, pinning potential, ...) leading to localization/delocalization transitions. I review some of the results that have been obtained. In particular, I discuss pinning by a local potential, entropic repulsion and the (pre)wetting transition, both for models with continuous and discrete heights.Published at http://dx.doi.org/10.1214/154957806000000050 in the Probability Surveys (http://www.i-journals.org/ps/) by the Institute of Mathematical Statistics (http://www.imstat.org)ProbabilityStatistical MechanicsMathematical Physics60K35, 82B41 (Primary) 82B24, 82B27 (Secondary)text
