---------- Forwarded message --------- Da: Andreas Kyprianou <ak257(a)bath.ac.uk> Date: mer 24 giu 2020 alle ore 13:23 Subject: [owps] One World Probability Seminar Thursday 25th June 2020 To: <owps(a)lists.bath.ac.uk> One World Probability Seminar Thursday 25th June 2020 Tomorrow's speakers in the One World Probability Seminar are ------------------------------------------------------------ 15.00: Augusto Teixeira (Rio): Random walks on dynamical random environments with non-uniform mixing (Part 1) 16.00: Marcelo Hilário (Belo Horizonte): Random walks on dynamical random environments with non-uniform mixing (Part 2) The first talk will be a non-technical introduction to the subject. ------------------------------------------------------------ Abstract: In these two consecutive talks we will discuss recent results on the limiting behavior of random walks on dynamical random environments. The strength of these results depends a great deal on space-time mixing properties imposed to the environment but also on other features like the dimension and the allowed transitions. In our case, we restrict ourselves to random walks evolving on one-dimensional random environments given by conservative interacting particle systems such as the simple symmetric exclusion process. For this setting, conservation of particles leads to poor-mixing conditions which complicates the applicability of some available tools. Our goal is to explain how renormalization can be used to handle these difficulties in order to obtain law of large numbers, large deviation estimates. The first talk will be a non-technical introduction to the subject. In the second talk, we provide a more detailed idea of how to prove the results. All the results were obtained on several joint works with Oriane Blondel, Frank den Hollander, Daniel Kious, Renato dos Santos and Vladas Sidoravicius. ------------------------------------------------------------ Please keep in mind that we are working with Central European summer time.

Probability Webminar: Lucio Galeati (University of Bonn) [Padova 26/06, 11.00]

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on June 26, 2020 at 11 by the zoom platform. ---------------------------------------------------- Speaker: Lucio Galeati (University of Bonn) Title: Regularisation by noise and notions of irregularity June 26, 2020 (Friday) - 11:00 - zoom link: TBA The link and password to access the seminar will be available at the following webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: A natural question in the field of regularisation by noise phenomena is to understand under which conditions on a path $w$, the additively perturbed ODE $x'=b(x)+w'$ is well-posed, even when its unperturbed counterpart $x'=b(x)$ is not. In order to answer this question, Catellier and Gubinelli (SPA 2016) introduced the theory of nonlinear Young integrals and the concept of $\rho$-irregularity of $w$; they also proved that fBm paths are $\rho$-irregular. In this talk, I will first review their work and then present its more recent extensions. The property of $\rho$-irregularity can be linked to the regularity of the local time of $w$ and, in the case of Gaussian processes, can be established under a suitable local non-determinism (LND) condition. Moreover, it can be shown that $\rho$-irregular paths are necessarily nowhere $\alpha$-Holder continuous, for suitable values $\alpha=\alpha(\rho)$. This gives a rigorous proof of the frequently observed paradigm "the rougher the noise, the better the regularisation". Based on joint works with Massiliano Gubinelli. --------------- David Barbato Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on July 3 at 11 by the zoom platform. ________________________________________________________ Speaker: Elena Pulvirenti (University of Bonn) Title: The Widom-Rowlinson model: metastability, mesoscopic and microscopic fluctuations for the critical droplet 3 JULY (Friday) - 11:00 - zoom link: TBA The link and password to access the seminar will be available at the following webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: We introduce the equilibrium Widom-Rowlinson model on a two-dimensional finite torus in which the energy of a particle configuration is attractive and determined by the union of small discs centered at the positions of the particles. We then discuss the metastable behaviour of a dynamic version of the WR model. This means that the particle configuration is viewed as a continuous time Markov process where particles are randomly created and annihilated as if the outside of the torus were an infinite reservoir with a given chemical potential. In particular, we start with the empty torus and are interested in the first time when the torus is fully covered by discs in the regime at low temperature and when the chemical potential is supercritical. In order to achieve the transition from empty to full, the system needs to create a sufficiently large droplet, called critical droplet, which triggers the crossover. We compute the distribution of the crossover time and identify the size and the shape of the critical droplet. The analysis relies on a mesoscopic and microscopic description of the surface of the critical droplet. It turns out that the critical droplet is close to a disc of a certain deterministic radius, with a boundary that is random and consists of a large number of small discs that stick out by a small distance. We will show how the analysis of surface fluctuations in the WR model allows us to derive the leading order term of the condensation time and also the correction order term. This is a joint work with Frank den Hollander (Leiden), Sabine Jansen (Munich) and Roman Kotecky (Prague & Warwick). -- 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/
