C. Berkeley) Title: Some exponents governing the geometry of planar last passage percolation and the directed landscape Abstract: Planar last passage percolation models are canonical examples of stochastic growth in the Kardar-Parisi-Zhang universality class, where one considers oriented paths between points in a random environment accruing the integral of the noise along itself as its weight. Given the endpoints, the extremal path with the maximum weight is termed as the geodesic. As the endpoints are allowed to vary in space and time (one dimension for each), the joint ensemble of the weights gives rise to a four parameter space-time random energy field, whose conjectural universal weak limit, the Directed landscape, was recently constructed in a breakthrough work of Dauvergne, Ortmann and Virag. We shall discuss a few recent results identifying exponents that govern the space time geometry of this fundamental object and its prelimits. In the first talk we shall study the aging behavior at short and large scales establishing exponents dictating the decay of correlations of weights in time, in last passage percolation on the lattice with exponential weights. We shall describe two results corresponding to the droplet and flat initial conditions confirming conjectures made by Ferrari and Spohn a few years ago. In the second talk we shall describe results on fractal geometry specializing to a Brownian model. In particular, we study the coupling structure of the geodesic weight profiles at a fixed time (say 1) started at distinct points at time 0 by analyzing their difference function. Though in expectation this grows linearly, we show that the difference profile induces a random measure whose support is fractal and compute its dimension. We also relate the support of this measure to the exceptional set of points admitting disjoint geodesics. Beyond geometric and probabilistic arguments involving geodesic behavior, the key inputs used are one point fluctuation information, locally Brownian nature of the geodesic weight profile, and sharp estimates on rarity of disjoint geodesics, the latter two being consequences of an invariance property under resampling termed as the Brownian Gibbs property. These talks are based on a number of works jointly with subsets of Erik Bates, Alan Hammond, and Lingfu Zhang. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://impa-br.zoom.us/j/93236291545?pwd=ZDBteUZEOGpSZWkrdVEyQXpXMUx0Zz09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fimpa-br.z…> Please feel free to circulate this email.

Padova Online Seminar by Federico Camia (NYU Abu Dhabi) [Friday, Nov. 06 at 14.00]
by alessandra bianchi 28 Oct '20

28 Oct '20

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on November 06 at 14 by the zoom platform. ________________________________________________________ Speaker: Federico Camia (NYU Abu Dhabi) Title: Critical and near-critical scaling limits for the planar Ising model 06 NOVEMBER (Friday) - 14:00 - zoom link: TBA (available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: The Ising model, proposed by Lenz in 1920 to describe ferromagnetism, is one the most studied models of statistical mechanics. Its two dimensional version has played a special role in rigorous statistical mechanics since Peierls’ proof of a phase transition in 1936 and Onsager’s derivation of the free energy in 1944. This continues to be the case today, thanks to new results on the continuum scaling limit. In this talk, I will first introduce the model and give a brief historical overview of some milestones in its analysis. I will then present recent results on its critical and near-critical scaling limits, focusing on the scaling behavior of the magnetization. In particular, I will discuss non-central limit theorems for the magnetization, the emergence of conformal invariance at the critical point, and exponential decay of correlations in the near-critical regime. (Based on joint work with R. Conijn, C. Garban, J. Jiang, D. Kiss, and C.M. Newman.) -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Pisa Online Seminars - Tal Orenshtein and Gennaro Ciampa (Tuesday, Oct. 27 at 14:00 and 15:00)
by Giacomo Filippo Di Gesu 23 Oct '20

23 Oct '20

Dear colleagues, I would like to announce the following online seminar organized by the Probability group of the University of Pisa. The talks will be accessible under the link Join Microsoft Teams Meeting<https://teams.microsoft.com/l/meetup-join/19%3A17115d7f6ef44c5e91974362906c…> Best regards, Giacomo Tuesday, Oct. 27, 14:00 Speaker: Tal Orenshtein (Berlin) Title: Aging in the Edwards-Wilkinson and KPZ universality classes. Abstract: Aging is an asymptotic property of non-equilibrium dynamical systems that captures non-trivial relaxation time temporal change; a canonical formulation is expressed in terms of the correlations of the system at two large times with a fixed relation. It was conjectured in Dembo-Deuschel '06 that one-dimensional KPZ models satisfy aging. In line with the progress on the one-time asymptotic behavior of KPZ in the past decade, this challenging problem gained attention in both the physics and the mathematical communities; there has been some experimental evidence for the phenomenon as well as related non-rigorous predictions and partial results. In the talk we shall see that for stationary systems one can use methods that rely solely on the variance asymptotics to achieve aging with an explicit aging function. We shall then derive aging for stationary models in the Edwards-Wilkinson universality class, which is easier to tackle. Moreover, we will demonstrate how to apply the methods to compute a formula for the space-time correlation scaling function in this case. In the remaining part of the talk we shall discuss aging for several stationary models in the KPZ class, including the KPZ fixed point, with the same aging function, matching the stationary KPZ equation prediction in Ferrari-Spohn '16. The talk is based on a recent work with Jean-Dominique Deuschel (TU Berlin) and Gregorio Moreno Flores (PUC Chile). Tuesday, Oct. 27, 15:00 Speaker: Gennaro Ciampa (Padova) Title: Strong convergence of the vorticity for the 2D Euler Equations in the inviscid limit Abstract: The goal of this talk is to study the inviscid limit of a family ω^ν of solutions of the 2D Navier-Stokes equations towards a renormalized/Lagrangian solution ω of the Euler equations. First I will prove the uniform-in-time L p convergence of ω^ν towards ω in the setting of unbounded vorticities. This improves a recent result proved by Constantin-Drivas-Elgindi in the bounded case. Then I will show that it is also possible to obtain an explicit rate in the class of solutions with bounded vorticity. The proofs are based on the stochastic Lagrangian formulation of the incompressible Navier-Stokes equations. In particular, the results are achieved by studying the zero-noise limit from stochastic towards deterministic flows of irregular vector fields. Based on a joint work with G. Crippa (Universität Basel) and S. Spirito (Università degli Studi dell’Aquila).
