We focus here on 2-scale convergence for random walks. In the first talk we aim to provide a gentle introduction to 2-scale convergence for random walks in a random environment with symmetric rates. Using the Palm theory of random measures we discuss ergodicity issues at a 2-scale level. We then introduce a basic difference calculus and define 2-scale convergence of functions and gradients, corresponding to an enforced averaging property. Finally we discuss the fundamental compactness and structure theorem for bounded families of H^1-functions, where geometrical issues of square integrable forms and the homogenized matrix emerge. In the second talk we discuss some applications of the above 2-scale convergence for random walks in a random environment. A first one is given by the invariance principle of random walks on the supercritical percolation cluster of P. Mathieu and A. Piatnitski. We then discuss more in detail applications to the homogenization of the massive Poisson equation associated with the random walk, which also enters in the derivation of the hydrodynamic limit of exclusion and zero range processes. Finally, we discuss applications to random resistor networks, in particular to the conductance model and the Miller-Abrahams one associated to Mott variable range hopping in amorphous solids. ------------------------------------------------ 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/94248802467?pwd=VlVQQzlsbjdKTHplRlRGbGlJRG5YUT09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fimpa-br.z…> Please feel free to circulate this email.

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/
