| Abstract | |
In this paper we obtain a decoupling feature of the random interlacements process I-u subset of Z(d), at level u, d >= 3. More precisely, we show that the trace of the random interlacements process on two disjoint finite sets, F and its translated F + x, can be coupled with high probability of success, when parallel to x parallel to is large, with the trace of a process of independent excursions, which we call the noodle soup process. As a consequence, we obtain an upper bound on the covariance between two {[}0, 1]-valued functions depending on the configuration of the random interlacements on F and F + x, respectively. This improves a previous bound obtained by Sznitman (Ann Math 2(171):2039-2087, 2010). (AU) | |
