چکیده
We prove that the Beta random walk, introduced in [BC17] 2017, has cubic fluctuations from large deviation principle of GUE Tracy-Widom type for arbitrary values ?>0 and ?>0 parameters distribution, removing previous restrictions on their values. Furthermore, we still hold intermediate disorder regime. also show any walk space-time environment matches certain moments with As a corollary emergence trajectories ending at boundary points walks space (time-independent) i.i.d. Dirichlet dimension d=2 class asymptotic behavior parameters.

Large Deviations for Random Walks in a Mixing Random Environment and Other (Non-Markov) Random Walks
We extend a recent work by S. R. S. Varadhan [8] on large deviations for random walks in a product random environment to include more general random walks on the lattice. In particular, some reinforced random walks and several classes of random walks in Gibbs fields are included. c © 2004 Wiley Periodicals, Inc.
متن کاملFluctuations and large deviations of some perturbed random matrices
General statement of the problem. The following algebraic problem is very classical: Let A and B be two Hermitian matrices of the same size. Assume we know the spectrum of each of them. What can be said about the spectrum of their sum A + B? The problem was posed by Weyl [1912]. He gave a series of necessary conditions, known as Weyl’s interlacing inequalities: if λ1(A)≥ · · · ≥ λn(A), λ1(B)≥ ·...

In this article, we establish a large deviation principle for the solutions of perturbed reflected diffusion processes. The key is to prove a uniform Freidlin-Ventzell estimates of perturbed diffusion processes.
متن کاملLarge Deviations Principle for Perturbed Conservation Laws
We investigate large deviations for a family of conservative stochastic PDEs (conservation laws) in the asymptotic of jointly vanishing noise and viscosity. We obtain a first large deviations principle in a space of Young measures. The associated rate functional vanishes on a wide set, the so-called set of measure-valued solutions to the limiting conservation law. We therefore investigate a sec...
متن کاملQuenched Free Energy and Large Deviations for Random Walks in Random Potentials
We study quenched distributions on random walks in a random potential on integer lattices of arbitrary dimension and with an arbitrary finite set of admissible steps. The potential can be unbounded and can depend on a few steps of the walk. Directed, undirected and stretched polymers, as well as random walk in random environment, are covered. The restriction needed is on the moment of the poten...
