Large deviation principle for the streams and the maximal flow in first passage percolation

Abstract

We consider the standard first passage percolation model in the rescaled lattice Zd\mathbb{Z}^d for d2d\geq 2 and a bounded domain Ω\Omega in Rd\mathbb R ^d. We denote by Γ1\Gamma^1 and Γ2\Gamma^2 two disjoint subsets of Ω\partial \Omega representing respectively the source and the sink, i.e., where the water can enter in Ω\Omega and escape from Ω\Omega. A maximal stream is a vector measure μnmax\overrightarrow{\mu}_n^{max} that describes how the maximal amount of fluid can enter through Γ1\Gamma^1 and spreads in Ω\Omega. Under some assumptions on Ω\Omega and GG, we already know a law of large number for μnmax\overrightarrow{\mu}_n^{max}. The sequence (μnmax)n1(\overrightarrow{\mu}_n^{max})_{n\geq 1} converges almost surely to the set of solutions of a continuous deterministic problem of maximal stream in an anisotropic network. We aim here to derive a large deviation principle for streams and deduce by contraction principle the existence of a rate function for the upper large deviations of the maximal flow in Ω\Omega.
