摘要:We prove that the local eigenvalue statistics in the bulk for complex random matrices with independent entries whose r-th absolute moment decays as N-1-(r-2)& varepsilon; for some & varepsilon;>0 are universal. This includes sparse matrices whose entries are the product of a Bernouilli random variable with mean N-1+& varepsilon; and an independent complex-valued random variable. By a standard truncation argument, we can also conclude universality for complex random matrices with 4+& varepsilon...

摘要:We study the critical branching random walk on Zd started from a distant point x and conditioned to hit some compact set K in Zd . We are interested in the occupation time in K and present its asymptotic behaviors in different dimensions. It is shown in this work that the occupation time is of order & Vert;x & Vert;4-d in dimensions d <= 3 , of order log & Vert;x & Vert; in dimension d=4 , and of order 1 in dimensions d >= 5 . The corresponding weak convergences are also established. These res...

摘要:We analyse the aggregate Loewner evolution (ALE), introduced in 2018 by Sola, Turner and Viklund to generalise versions of diffusion limited aggregation (DLA) in the plane using complex analysis. They showed convergence of the ALE for certain parameters to a single growing slit. Started from a non-trivial initial configuration of k needles and the same parameters, we show that the small-particle scaling limit of ALE is the Laplacian path model, introduced by Carleson and Makarov, in which the ...

摘要:We consider a parabolic stochastic partial differential equation (SPDE) on [0, 1] that is forced with multiplicative space-time white noise with a bounded and Lipschitz diffusion coefficient and a drift coefficient that is locally Lipschitz and satisfies an LlogL growth condition. We prove that the SPDE is well posed when the initial data is in L-2[0,1]. This solves a strong form of an open problem.

摘要:We study the nonlocal Stefan problem, where the phase transition is described by a nonlocal diffusion as well as the change of enthalpy functions. By using a stochastic optimization approach introduced in Kim and Kim (The Stefan problem and free targets of optimal Brownian martingale transport, 2021. arXiv preprint arXiv:2110.03831), we construct global-time weak solutions and give a probabilistic interpretation for the solutions. An important ingredient in our analysis is a probabilistic inte...

摘要:Wiener spaces are in many ways the decisive setting for fundamental results on Gaussian measures: large deviations (Schilder), quasi-invariance (Cameron-Martin), differential calculus (Malliavin), support description (Stroock-Varadhan), concentration of measure (Fernique), ...Analogues of these classical results have been derived in the enhanced context of Gaussian rough paths and, more recently, regularity structures equipped with Gaussian models. The aim of this article is to propose a simil...

摘要:We prove that the supercritical phase of Voronoi percolation on R-d, d >= 3, is well behaved in the sense that for every p>p(c)(d) local uniqueness of macroscopic clusters happens with high probability. As a consequence, truncated connection probabilities decay exponentially fast and percolation happens on sufficiently thick 2D slabs. This is the analogue of the celebrated result of Grimmett and Marstrand for Bernoulli percolation and serves as the starting point for renormalization techniques...
