Abstract

Let {YB(x):xB}\{Y_{\mathfrak{B}}(x)\,:\,x\in\mathfrak{B}\} be a discrete Gaussian free field in a two-dimensional box B\mathfrak{B} of side length SS with Dirichlet boundary conditions. We study Liouville first-passage percolation: the shortest-path metric in which each vertex xx is given a weight of eγYB(x)e^{\gamma Y_{\mathfrak{B}}(x)} for some γ>0\gamma>0. We show that for sufficiently small but fixed γ>0\gamma>0, for any sequence of scales {Sk}\{S_{k}\} there exists a subsequence along which the appropriately scaled and interpolated Liouville FPP metric converges in the Gromov--Hausdorff sense to a random metric on the unit square in R2\mathbf{R}^{2}. In addition, all possible (conjecturally unique) scaling limits are homeomorphic by bi-H\"older-continuous homeomorphisms to the unit square with the Euclidean metric.
