Uniqueness for a class of one-dimensional stochastic PDEs using moment duality
Abstract
For independent nearest-neighbour bond percolation on Z^d with d >> 6, we prove that the incipient infinite cluster's two-point function and three-point function converge to those of integrated super-Brownian excursion (ISE) in the scaling limit. The proof is based on an extension of the new expansion for percolation derived in a previous paper, and involves treating the magnetic field as a complex variable. A special case of our result for the two-point function implies that the probability that the cluster of the origin consists of n sites, at the critical point, is given by a multiple of n^{-3/2}, plus an error term of order n{-3/2-\epsilon} with \epsilon > 0. This is a strong statement that the critical exponent \delta is given by \delta = 2.
