We consider the standard first passage percolation model in the rescaled lattice \mathbb Zd/n for d≥ 2 and a bounded domain Ω in \mathbb Rd. We denote by Γ1 and Γ2 two disjoint subsets of ∂ Ω representing respectively the sources and the sinks, i.e., where the water can enter in Ω and escape from Ω. A cutset is a set of edges that separates Γ1 from Γ2 in Ω, it has a capacity given by the sum of the capacities of its edges. Under some assumptions on Ω and the distribution of the capacities of the edges, we already know a law of large numbers for the sequence of minimal cutsets (\mathcal Enmin)n≥ 1: the sequence (\mathcal Enmin)n≥ 1 converges almost surely to the set of solutions of a continuous deterministic problem of minimal cutset in an anisotropic network. We aim here to derive a large deviation principle for cutsets and deduce by contraction principle a lower large deviation principle for the maximal flow in Ω.
