Let d ≥ 2. We consider an i.i.d. supercritical bond percolation on Z d , every edge is open with a probability p > p c (d), where p c (d) denotes the critical point. We condition on the event that 0 belongs to the infinite cluster C ∞ and we consider connected subgraphs of C ∞ having at most n d vertices and containing 0. Among these subgraphs, we are interested in the ones that minimize the open edge boundary size to volume ratio. These minimizers properly rescaled converge towards a translate of a deterministic shape and their open edge boundary size to volume ratio properly rescaled converges towards a deterministic constant.
We consider an i.i.d. supercritical bond percolation on Z d , every edge is open with a probability p > p c (d), where p c (d) denotes the critical parameter for this percolation. We know that there exists almost surely a unique infinite open cluster C p [11]. We are interested in the regularity properties of the chemical distance for supercritical Bernoulli percolation. The chemical distance between two points x, y ∈ C p corresponds to the length of the shortest path in C p joining the two points. The chemical distance between 0 and nx grows asymptotically like nµ p (x). We aim to study the regularity properties of the map p → µ p in the supercritical regime. This may be seen as a special case of first passage percolation where the distribution of the passage time isIt is already known that the map p → µ p is continuous (see [10]).
We consider the standard first passage percolation model in the rescaled lattice Z d /n for d ≥ 2 and a bounded domain Ω in R d . We denote by Γ 1 and Γ 2 two disjoint subsets of ∂Ω representing respectively the source and the sink, i.e., where the water can enter in Ω and escape from Ω. A maximal stream is a vector measure − → µ max n that describes how the maximal amount of fluid can enter through Γ 1 and spreads in Ω. Under some assumptions on Ω and G, we already know a law of large number for − → µ max n . The sequence ( − → µ max n ) n≥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.
We consider an i.i.d. supercritical bond percolation on Z^d, every edge is open with a probability p > p_c(d), where p_c(d) denotes the critical parameter for this percolation. We know that there exists almost surely a unique infinite open cluster C_p [11]. We are interested in the regularity properties of the chemical distance for supercritical Bernoulli percolation. The chemical distance between two points x, y ∈ C_p corresponds to the length of the shortest path in C_p joining the two points. The chemical distance between 0 and nx grows asymptotically like nµ_p(x). We aim to study the regularity properties of the map p → µ_p in the supercritical regime. This may be seen as a special case of first passage percolation where the distribution of the passage time is G_p = pδ_1 + (1 − p)δ_∞, p > p_c(d). It is already known that the map p → µ_p is continuous (see [10]).
We consider an i.i.d. supercritical bond percolation on Z d , every edge is open with a probability p > p c (d), where p c (d) denotes the critical parameter for this percolation. We know that there exists almost surely a unique infinite open cluster C p [7]. We are interested in the regularity properties in p of the anchored isoperimetric profile of the infinite cluster C p . For d ≥ 2, we prove that the anchored isoperimetric profile defined in [4] is Lipschitz continuous on all intervals [p 0 , p 1 ] ⊂ (p c (d), 1).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
