title: | Entropic repulsion on a rarefied wall |

keywords: | harness process, surface dynamics, entropic repulsion, random environment |

abstract: | We consider the motion of a discrete d-dimensional random surface interacting by exclusion with a rarefied wall. The dynamics is given by the serial harness process. We prove that the process delocalizes iff the mean number of visits to the set of sites where the wall is present by some random walk is infinite. In case where there is a delocalization, bounds on its speed are obtained. |

The first *source* gives you
the `gzipped' PostScript, the second the plain PostScript and the
third the format for the Adobe accrobat reader. Depending on the
installation of your web browser, at least one of these should
(after some amount of time) pop up a window for you that shows
the full article. If this is not the case, you should contact
your system administrator to install your browser
correctly.

Due to limitations of your local software, the two formats may show up differently on your screen. If eg you use xpdf to visualize pdf, some of the graphics in the file may not come across. On the other hand, pdf has a capacity of giving links to sections, bibliography and external references that will not appear with PostScript.
