摘要：We consider the Allen-Cahn equation ?(t)u - ?u = u - u(3) with a rapidly mixing Gaussian field as initial condition. We show that provided that the amplitude of the initial condition is not too large, the equation generates fronts described by nodal sets of the Bargmann-Fock Gaussian field, which then evolve according to mean curvature flow.

摘要：Let X-1, X-2, . . . be independent random uniform points in a bounded domain A subset of R-d with smooth boundary. Define the coverage threshold Rn to be the smallest r such that A is covered by the balls of radius r centred on X-1, . . . , X-n. We obtain the limiting distribution of R(n )and also a strong law of large numbers for R-n in the large -n limit. For example, if A has volume 1 and perimeter |& part; A|, if d = 3 then P[n pi R-n(3) - log n - 2 log(log n) <= x] converges to exp(-2(-4)...

摘要：The explicit biorthogonalization method, developed in [24] for continuous time TASEP, is generalized to a broad class of determinantal measures which describe the evolution of several interacting particle systems in the KPZ universality class. The method is applied to sequential and parallel update versions of each of the four variants of discrete time TASEP (with Bernoulli and geometric jumps, and with block and push dynamics) which have determinantal transition probabilities; to continuous t...

摘要：Given a convex function 0 : [0, 1] ? R and the mean ? f (X) = a ? [0, 1], which Boolean function f maximizes the 0-stability E[F (T-? f(X))] of f ? Here X is a random vector uniformly distributed on the discrete cube {-1, 1}n and T(? )is the Bonami-Beckner operator. Special cases of this problem include the (symmetric and asymmetric) a-stability problems and the Most Informative Boolean Function problem. In this paper, we provide several upper bounds for the maximal 0-stability. When specializ...

摘要：We establish universality for the largest singular values of products of random matrices with right unitarily invariant distributions, in a regime where the number of matrix factors and size of thematrices tend to infinity simultaneously. The behavior of the largest log singular values coincides with the large N limit of Dyson Brownian motion with a characteristic drift vector consisting of equally spaced coordinates, which matches the large N limit of the largest log singular values of Browni...

摘要：Themain aim of thiswork is to study the asymptotic behavior formulti-scaleMcKeanVlasov stochastic dynamical systems. Firstly, we obtain a central limit type theorem, i.e. the deviation between the slow component X-epsilon and the solution X- of the averaged equation converges weakly to a limiting process. More precisely, X epsilon-X-|root epsilon v e converges weakly in C([0, T], R-n) to the solution of certain distribution dependent stochastic differential equation, which involves an extra ex...

摘要：We compute the free energy at all temperatures for the spherical pure p-spin models from the generalized Thouless-Anderson-Palmer representation. This is the first example of a mixed p-spin model for which the free energy is computed in the whole replica symmetry breaking phase, without appealing to the famous Parisi formula.

摘要：This paper deals with the problem of graph matching or network alignment for Erdos- Renyi graphs, which can be viewed as a noisy average-case version of the graph isomorphism problem. Let G and G' be G(n, p) Erdos-Renyi graphs marginally, identified with their adjacency matrices. Assume that G and G' are correlated such that E[G(ij)G'(ij)] = p(1 - alpha). For a permutation pi representing a latent matching between the vertices of G and G', denote by G(pi) the graph obtained from permuting the ...

摘要：Consider the restriction of the directed landscape L(x, s; y, t) to a set of the form {x(1), . . . , x(k)} x {s(0)} x R x {t(0)}. We show that on any such set, the directed landscape is given by a last passage problem across k locally Brownian functions. The k functions in this last passage isometry are built from certain marginals of the extended directed landscape. As applications of this construction, we show that the Airy difference profile is locally absolutely continuous with respect to ...

摘要：We study distribution dependent stochastic differential equations with irregular, possibly distributional drift, driven by an additive fractional Brownian motion of Hurst parameter H is an element of (0, 1). We establish strong well-posedness under a variety of assumptions on the drift; these include the choice B(., mu) = (f * mu)(.) + g(.), f, g is an element of B-infinity,infinity(alpha), alpha > 1 - 1/2H, thus extending the results by Catellier and Gubinelli (Stochast Process Appl 126(8):23...
