%0 Journal Article %T Space-time correlations of a Gaussian interface %A Francois M. Dunlop %J Mathematics %D 2010 %I arXiv %X The serial harness introduced by Hammersley is equivalent, in the Gaussian case, to the Gaussian Solid-On-Solid interface model with parallel heat bath dynamics. Here we consider sub-lattice parallel dynamics, and give exact results about relaxation dynamics, based on the equivalence to the infinite time limit of a time periodic random field. We also give a numerical comparison to the harness process in continuous time studied by Hsiao and by Ferrari, Niederhauser and Pechersky. %U http://arxiv.org/abs/1002.1604v1
