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).

Fwd: [owps] One World Probability Seminar Thursday October 22, 2020

21 Oct '20

---------- Forwarded message --------- Da: Ivan Corwin <ivan.corwin(a)gmail.com> Date: mer 21 ott 2020 alle ore 15:50 Subject: [owps] One World Probability Seminar Thursday October 22, 2020 To: <owps(a)lists.bath.ac.uk> One World Probability Seminar Thursday October 22, 2020: Tomorrow's speaker in the One World Probability Seminar is (Note: all times are in UTC) ------------------------------------------------ (14:00-15:00 UTC) Lionel Levine (Cornell University) Abelian Sandpiles and Abelian Networks. Abstract: The Abelian Networks are a class of interacting particle systems whose final state does not depend on the order of interactions. A revealing example is the Abelian Sandpile of Bak-Tang-Wiesenfeld, a toy model of sand cascading down a pile. This model has certain “non-universal” features, and we'll identify "slow mixing" as the culprit: The threshold state of the sandpile retains some memory of its initial state. Then we’ll explore the design space of Abelian Networks in search of a model with more universal features. A promising candidate is Activated Random Walk. (15:00-16:00 UTC) Leonardo Rolla (NYU-Shanghai, IMAS-Conicet, Warwick) Abstract: In this second talk, we will discuss one specific type of stochastic Abelian network called Activated Random Walks. Long-range effects intrinsic to its conservative dynamics and lack of a simple algebraic structure cause standard tools and techniques to break down, which makes the mathematical study of this model remarkably challenging. Yet, some exciting progress has been made in the last ten years, with the development of a framework of tools and methods which is finally becoming more structured. We will briefly recall the existing results and open problems, then focus on recent progress for one-dimensional symmetric walks with at density (Basu-Ganguly-Hoffman 2018), enhancement and continuity of the critical curve (Taggi 2020), scaling limit at criticality (Cabezas-myself 2020), symmetric walks at high sleep rate (Hoffman-Richey-myself 2020), and linear growth (Levine-Silvestri 2020). ------------------------------------------------ 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/96520705847?pwd=MFJtMXIzVUFmN0w0aVZ3QktIZnBpUT09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fimpa-br.z…> Please feel free to circulate this email.

STAR Seminar announcement: Speaker Samy Tindel, University of Purdue, Indiana
by michele giordano 21 Oct '20

21 Oct '20

Dear all, This is a reminder for the: STAR Online Seminars. The seminar will be held Friday 23. October from 11:00-12:00 . You will recieve the link for the Zoom room by registering for the seminar with the link provided at the end of this mail. The lecture will last for 45 minutes + questions. This week's speaker is Samy Tindel - University of Perdue, Indiana, with the seminar: A coupling between Sinai’s random walk and Brox diffusion Abstract: Sinai’s random walk is a standard model of 1-dimensional random walk in random environment. Brox diffusion is its continuous counterpart, that is a Brownian diffusion in a Brownian environment. The convergence in law of a properly rescaled version of Sinai’s walk to Brox diffusion has been established 20 years ago. In this talk, I will explain a strategy which yields the convergence of Sinai’s walk to Brox diffusion thanks to an explicit coupling. This method, based on rough paths techniques, opens the way to rates of convergence in this demanding context. Notice that I’ll try to give a maximum of background about the objects I’m manipulating, and will keep technical considerations to a minimum. After the end of the seminar, you are invited to bring a cup of coffee/tea and have a chat in our Coffee in the Stars here you will have the chance to talk and interact with the other persons that attended the seminar, and have a digital "coffee break". We are looking forward to see you, online! Best regards, We are looking forward to see you, online!

by Stefano Favaro 21 Oct '20

21 Oct '20

Ricevo e inoltro. **** Hi Stefano, I am writing to you to advertise for potential postdoc positions in my department. ---------------------------------------------------------------------- Details about the funding opportunity: The Jacques Hadamard foundation offers 7 post-doc grants for positions starting in October 2021 (Deadline for application is December 1st, 2020 <http://airmail.calendar/2020-12-01%2012:00:00%20UTC+1>). The duration of the postdoc will be 2 years. As for the previous years, candidates are allowed to submit their own research projects. For the first time, however, this year the foundation has retained a certain number of selected topics from its affiliated laboratories. I believe there is more chance of success for candidates applying on one of those topics. I have submitted one of the selected topic in ML. If you know potential candidates, I’de be happy to push their application. I cannot guarantee the funding, but I know that priority will be given to ML/AI topics, so there is a decent chance of success for strong candidates. Finally, let me add that I have proposed a ML oriented topic, but I am willing to consider all applications in relation with my other center of interests (statistics theory, Bayesian nonparametrics, etc..) More details about the funding application here: https://www.fondation-hadamard.fr/en/funding/accueil-294-postdoctoral-fello… <https://www.fondation-hadamard.fr/en/funding/accueil-294-postdoctoral-fello…> ---------------------------------------------------------------------- A few words about the university and the department: With 275 laboratories shared with the CEA, CNRS, IHES, INRAE, INRIA, INSERM, Onéra, Université Paris-Saclay represents 13% of the French research potential. Located south of Paris, on a vast territory (from Paris to Orsay, via Evry and Versailles), Université Paris-Saclay benefits from a strategic geographical and socio-economic position enhanced by its international visibility. Université Paris-Saclay operates on a classified and protected natural site, close to Paris, and at the heart of a particularly dynamic ecosystem. With of 48,000 students, 9,000 professors and lecturers, and 11,000 technical and administrative staff, Université Paris-Saclay is a driving force for the development of its territory and one of the best institutions in France. https://www.universite-paris-saclay.fr/en/about/universite-paris-saclay <https://www.universite-paris-saclay.fr/en/about/universite-paris-saclay> The Institut de Mathématiques d’Orsay (IMO) is the largest mathematical department of Université Paris-Saclay with more than 150 researchers (+ more than 100 PhD students). Most of areas of mathematics are represented within 5 groups (Harmonic analysis, PDEs, Arithmetic and algebraic geometry, Probability and Statistics, Topology). Hence, working at the IMO is a good opportunity to mix with excellent researchers and students from all disciplines. The IMO is located in Orsay, approximately 45min from Paris center by train. In July 2020, the University ranked 1st in Shanghai ranking’s in mathematics. https://www.imo.universite-paris-saclay.fr/ <https://www.imo.universite-paris-saclay.fr/> ---------------------------------------------------------------------- Best regards, — Zacharie Naulet

Fwd: new online Joint Israeli Probability Seminar
by Pietro Caputo 19 Oct '20

19 Oct '20

ricevo e inoltro: ============================================================= We would like to invite you to participate in the new online Joint Israeli Probability Seminar. JIPS is a new initiative joint between: - Bar-Ilan University - Ben-Gurion University of the Negev - Hebrew University of Jerusalem - Technion - Israel Institute of Technology - Tel Aviv University - Weizmann Institute of Science The purpose of the seminar is to bring together researchers from around the globe studying various aspects of probability theory. The seminar will take place on Tuesdays and will usually consist of two talks - at 10am and 11am Israel time (9am & 10am CET). The seminar will be using the Zoom platform. Talks will be recorded and available online. We announce the first two talks below. If you would like to get future announcements you can either follow the JIPS calendar - HERE <https://calendar.google.com/calendar/embed?src=o9sgdbqi3ftt42aobpmphnjbic%4…>, or join the seminar mailing group - HERE <https://groups.google.com/g/joint-israeli-probability-seminar>. You can find more information on the seminar website: https://sites.google.com/view/israel-prob-sem/home We hope to virtually see you @ JIPS. JIPS organizers: Omer Bobrowski - Technion Naomi D. Feldheim - Bar Ilan University Ohad N. Feldheim - Hebrew University of Jerusalem Gady Kozma - Weizmann Institute of Science Ron Peled - Tel Aviv University Eviatar B. Procaccia - Technion Ariel Yadin - Ben-Gurion University of the Negev ================================================== The first two talks will take place on Tuesday 20/10/20. 10-11: *Clement Cosco(WIS) / Directed polymers on infinite graphs* We study the directed polymer model for general infinite graphs and random walks. We provide sufficient conditions for the existence or non-existence of phase transitions in terms of properties of the graph and of the random walk. We study in some detail (biased) random walk on various trees including the Galton-Watson trees, and provide a range of other examples that illustrate counter-examples to intuitive extensions of the simple random walk on the lattice. (Joint work with Inbar Seroussi and Ofer Zeitouni) 11-12: *Ofer Zeitouni (WIS) / Minima of random polynomials* We consider Gaussian random trigonometric polynomials and prove a limit theorem for their minimum modulus on the unit circle. I will describe the relevant background and various techniques employed in this and related problems. Somewhat surprisingly, a crucial step in the proof involves a characterization of Poisson processes due to Liggett, and its refinement due to Biskup-Louidor. (Joint work with Oren Yakir, TAU)
