Actions in the Airy line ensemble and convergence to the Airy sheet

Balint Virag, Xuan Wu

Actions in the Airy line ensemble represent distances from an infinitely far object. We characterize the Airy sheet by S(x,.)=T^x(.,1), where T^x is the unique action in the Airy l…

The directed landscape seen from its trees

Mustazee Rahman, Balint Virag

A basic question about the directed landscape is how much of it can be reconstructed simply by knowing the shapes of its geodesics. We prove that the directed landscape can be reco…

KPZ fluctuations in the planar stochastic heat equation

Jeremy Quastel, Alejandro Ramirez, Balint Virag

We use a version of the Skorokhod integral to give a simple and rigorous formulation of the Wick-ordered (stochastic) heat equation with planar white noise, representing the free e…

Infinite geodesics, competition interfaces and the second class particle in the scaling limit

Mustazee Rahman, Balint Virag

We establish fundamental properties of infinite geodesics and competition interfaces in the directed landscape. We construct infinite geodesics in the directed landscape, establish…

Amenability of quadratic automaton groups

Gideon Amir, Omer Angel, Balint Virag

We give lower bounds for the electrical resistance between vertices in the Schreier graphs of the action of the linear (degree 1) and quadratic (degree 2) mother groups on the orbi…

The heat and the landscape I

Balint Virag

Heat flows in 1+1 dimensional stochastic environment converge after scaling to the random geometry described by the directed landscape. In this first part, we show that the O'Conne…

Operator limits of random matrices

Balint Virag

We present a brief introduction to the theory of operator limits of random matrices to non-experts. Several open problems and conjectures are given. Connections to statistics, inte…

Tracy-Widom fluctuations in 2D random Schrodinger operators

Marcin Kotowski, Bálint Virág

We construct a random Schrodinger operator on a subset of the hexagonal lattice and study its smallest positive eigenvalues. Using an asymptotic mapping, we relate them to the part…

Brownian motion as limit of the interchange process

Mustazee Rahman, Balint Virag

We prove that the random empirical measure of appropriately rescaled particle trajectories of the interchange process on path graphs converges weakly to the deterministic measure o…

Geometry of Permutation Limits

Mustazee Rahman, Balint Virag, Mate Vizer

This paper initiates a limit theory of permutation valued processes, building on the recent theory of permutons. We apply this to study the asymptotic behaviour of random sorting n…

Eigenvectors of the critical 1-dimensional random Schroedinger operator

Ben Rifkind, Balint Virag

The purpose of this paper is to understand in more detail the shape of the eigenvectors of the random Schroedinger operator H = Delta+V. Here Delta is the discrete Laplacian and V…

The Sine operator

Benedek Valkó, Bálint Virág

We show that Sine, the bulk limit of the Gaussian -ensembles is the spectrum of a self-adjoint random differential operator \[ f\to 2 {R_t^{-1}} \left[ \begin{array}{cc} 0 &…

Dyson's spike for random Schroedinger operators and Novikov-Shubin invariants of groups

Marcin Kotowski, Bálint Virág

We study Schroedinger operators with random edge weights and their expected spectral measures near zero. We prove that the measure exhibits a spike of the form $μ_H(-\varepsi…

Hölder continuity of the integrated density of states in the one-dimensional Anderson model

Eric Hart, Balint Virag

We consider the one-dimensional random Schrodinger operator H = H_0 + sigma V, where the potential V has i.i.d. entries with bounded support. We prove that the IDS is Holder contin…

A central limit theorem for products of random matrices and GOE statistics for the Anderson model on long boxes

Christian Sadel, Bálint Virág

We consider products of random matrices that are small, independent identically distributed perturbations of a fixed matrix . Focusing on the eigenvalues of of a particu…

Local algorithms for independent sets are half-optimal

Mustazee Rahman, Balint Virag

We show that the largest density of factor of i.i.d. independent sets on the d-regular tree is asymptotically at most (log d)/d as d tends to infinity. This matches the lower bound…

Mean quantum percolation

Charles Bordenave, Arnab Sen, Balint Virag

We study the spectrum of adjacency matrices of random graphs. We develop two techniques to lower bound the mass of the continuous part of the spectral measure or the density of sta…

Universality of the Stochastic Airy Operator

Manjunath Krishnapur, Brian Rider, Balint Virag

We introduce a new method for studying universality of random matrices. Let T_n be the Jacobi matrix associated to the Dyson beta ensemble with uniformly convex polynomial potentia…

Invariant Gaussian processes and independent sets on regular graphs of large girth

Endre Csóka, Balázs Gerencsér, Viktor Harangi +1

We prove that every 3-regular, n-vertex simple graph with sufficiently large girth contains an independent set of size at least 0.4361n. (The best known bound is 0.4352n.) In fact,…
