Eurandom workshop “Interacting particles in the continuum", 9-13 September 2024
by Vanessa Jacquier 21 Jun '24

21 Jun '24

Inoltro per conoscenza: Dear colleagues, the registration is now open for the workshop *“**Interacting particles in the continuum**"* *taking place September 09-13 2024 at EURANDOM in Eindhoven* The goal of the workshop is to bring together researchers that work on various aspects of stochastic interacting systems in continuous space. This includes for example interacting particles in the continuum, their equilibrium and metastable behavior as well as stochastic dynamics of such systems. A special focus of the workshop also lies on the influence of geometry in natural random objects such as Brownian motion, Gibbs point processes and interacting Markovian systems. This EURANDOM event thrives to provide a platform for the lively exchange of national and international researchers on every career level. Ten dedicated 30 min contributed talks will be competitively distributed to young scientists based on abstract proposals. *Speakers:* Prof. Fabrice Baudoin, Aarhus University (Keynote) Prof. Sabine Jansen, LMU Munich (Keynote) Chiara Boccato, University of Milan Florian Theil, University of Warwick Anja Sturm, University of Goettingen Christof Kuelske, University of Bochum Elena Pulvirenti, TU Delft David Dereudre, University of Lille Pierre Perruchaud, University of Luxemburg Rik Versendaal, TU Delft Anna Paola Todino, University of Piemonte Jonathan Junné, TU Delft Richard Kraaij, TU Delft *Call for abstracts from young researchers:* The program provides a few slots each afternoon for talks reserved for young researchers. We fill these slots based on a competitive abstract submission. If you are interested in giving a talk, please send an email to Benedikt Jahnel (Benedikt.Jahnel(a)wias-berlin.de <w.l.f.v.d.hoorn(a)tue.nl>) (by July 14 2024) that includes title and abstract for your proposed talk. Additionally we plan a poster session. More details and registration can be found at https://www.eurandom.tue.nl/event/gibbs-point-processes-and-applications/ Registration is free but mandatory. We look forward to seeing you in Eindhoven, with best regards, Wioletta Ruszel, Frank Redig, Benedikt Jahnel --------------------------------------- Vanessa Jacquier *Post-doctoral researcher * Department of Mathematics University of Utrecht Budapestlaan 6, 3584 CD *Utrecht*, The Netherlands.

The candidates will work in the context of the project "SMILE: Statistical Machine Learning for Exposure development", funded by the Italian Ministry of University and Research (MUR) through the PRIN 2022 PNRR program. A Master's Degree in Computer Science, Data Science, Computer Engineering, Sciences and technologies for the environment and the territory, or Mathematics is required. - Duration: 12 months each - Start of the contract: November 1, 2024 - Salary: monthly net of about 2,000 Euro - Deadline: July 8, 2024 at 12:00 (Rome time) Apply here: https://www.unimib.it/ateneo/gare-e-concorsi/cod-24a143 If you are interested, and for more information please contact: gianluigi.ciocca(a)unimib.it Brief description of the project The purpose of the research is the study of machine learning techniques for the extraction of information inherent the type, characteristics, and distribution of buildings on a given territory. This information will be used to assess the exposure development of the territory to potential risk situations. To this end, the data expected to be analyzed will be heterogeneous and may come from aerial imagery (e.g. remote sensing), land use data surveyed by public administrations (e.g. ISTAT-National Institute of Statistics) and crowd-sourced data collected by trained citizens. Artificial intelligence tools such as deep neural networks applicable to image classification, object detection and semantic segmentation are expected to be used in the development of this study.

Seminario Mattia Martini - Politecnico di Milano - 28 Giugno 2024

Si segnala il seguente seminario a tutti gli interessati. Venerdì 28 Giugno 2024, ore 11. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Mattia Martini, Laboratoire J.A. Dieudonné, Université Cotê d’Azur. Title: Fourier Galerkin approximation of mean field control problems. Abstract: Over the past twenty years, mean field control theory has been developed to study cooperative games between weakly interacting agents (particles). The limiting formulation of a (stochastic) mean field control problem, arising as the number of agents approaches infinity, is a control problem for trajectories with values in the space of probability measures. The goal of this talk is to introduce a finite dimensional approximation of the solution to a mean field optimal control problem set on the d-dimensional torus, without relying on particle-based methods. Our approximation is obtained by means of a Fourier-Galerkin method, the main principle of which is to truncate the Fourier expansion of probability measures. However, this operation has the main feature not to leave the space of probability measures invariant, which drawback is know as Gibbs’ phenomenon. We prove that the Fourier-Galerkin method induces a new finite-dimensional control problem with trajectories in the space of probability measures with a finite number of Fourier coefficients. We also present convergence results for the optimal control, trajectory, and value function, showing that our method achieves faster convergence rates than the usual particle approach, offering a more efficient alternative. This talk is based on joint work with François Delarue.

Seminario Daniela Bertacchi - Politecnico di Milano - 20 Giugno 2024

Si segnala il seguente seminario a tutti gli interessati. Giovedì 20 Giugno 2024, ore 11. Aula Seminari Mox VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Daniela Bertacchi, Università di Milano-Bicocca. Title: A new stochastic order applied to branching random walks. Abstract: Stochastic ordering is a powerful tool to compare random variables and processes. We introduce a new type of stochastic ordering which generalizes the germ order introduced by Hutchcroft in 2022, which uses the generating function of the process. We apply this order to compare different branching random walks on a countable space $X$. We prove that given two branching random walks with law $\mu$ and $\nu$ respectively, with $\mu\ge\nu$, then in every set where there is extinction according to $\mu$, there is extinction also according to $\nu$. Moreover, in every set where there is strong local survival according to $\nu$, there is strong local survival also according to $\mu$, provided that the supremum of the global extinction probabilities, for the $\nu$-process, taken over all starting points $x$, is strictly smaller than 1. New conditions for survival and strong survival for inhomogeneous branching random walks are provided. We also extend a result of Moyal (1962), on the properties of fixed points of the generating function of a branching random walk.
