Seminario di Probabilità - Padova

16 Nov '16

Ho il piacere di invitarvi al seguente seminario, che si terrà Giovedì 24 novembre, alle 14:30, in aula 2BC30 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. SPEAKER: Sander Dommers AFFILIATION: University of Bochum TITLE: Metastability in the reversible inclusion process ABSTRACT: In the reversible inclusion process with N particles on a finite graph each particle at a site x jumps to site y at rate (d+\eta_y) r(x,y), where d is a diffusion parameter, \eta_y is the number of particles on site y and r(x,y) is the jump rate from x to y of an underlying reversible random walk. When the diffusion d goeas to 0 as N goeas to infinity, the particles cluster together to form a condensate. It turns out that these condensates only form on the sites where the underlying random walk spends the most time. Once such a condensate is formed the particles stick together and the condensate performs a random walk itself on much longer timescales, which can be seen as metastable behavior. We study the rates at which the condensate jumps and show that in the reversible case there are three time scales on which these jumps occur depending on how far (in graph distance) the sites are from each other. This generalizes work by Grosskinsky, Redig and Vafayi who study the symmetric case where only one timescale is present. Our analysis is based on potential theory and the martingale approach by Beltrán and Landim. This is joint work with Alessandra Bianchi and Cristian Giardinà. -- 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/

Dipartimento di Matematica, Sapienza Università di Roma Martedì 22 novembre Ore 14:00, Aula di Consiglio Seminario di Probabilità e Statistica Matematica Carlo Orrieri, Dipartimento di Matematica, Sapienza Università di Roma *Controlled Vlasov-type dynamics* *Abstract: The aim of the talk is to connect the optimal control of Vlasov-type PDEs with large systems of controlled interacting particles/agents. The main difference towards the classical mean-field theory, where the particle are freely interacting with each other, is the presence of a central planner influencing the dynamics. In this situation it is not obvious that the mean field limit should commute with the optimization. In order to develop a rigorous limit theory for this problem we employ the well-known concept of Gamma convergence.* *The talk is based on a work in project with M. Fornasier, S. Lisini and G. Savaré* Tutti gli interessati sono invitati a partecipare. Per qualsiasi richiesta di informazione scrivere a piccioni(a)mat.uniroma1.i <piccioni(a)mat.uniroma1.it>

Seminario di Giorgio Ferrari presso la Luiss, Mercoledi' 16 Novembre
by Fausto Gozzi 15 Nov '16

15 Nov '16

Luiss, Roma, Dipartimento di Economia e Finanza Viale Romania 32, Roma Mercoledi' 16 Novembre ore 18.10 aula 106 b Seminario di Giorgio Ferrari (Universitat Bielefeld) TITLE: Stochastic nonzero-sum games: a new connection between singular control and optimal stopping ABSTRACT: In this talk I present a new connection between a class of 2-player nonzero-sum games of optimal stopping and certain 2-player nonzero-sum games of singular control. I show that whenever a Nash equilibrium in the game of stopping is attained by hitting times at two separate boundaries, then such boundaries also trigger a Nash equilibrium in the game of singular control. Moreover a differential link between the players' value functions holds across the two games. An application to a problem of pollution control is finally discussed. The talk is based on a joint work with Tiziano De Angelis (The University of Leeds). Tutti gli interessati sono invitati a partecipare.

seminar announcemnt
by Marco Scarsini 10 Nov '16

Thursday 17 November from 12.00 to 13.00 LUISS room 207 viale Romania 32 00197 Roma. Speaker: Sylvain Gibaud (Institut de Mathématiques de Toulouse) Title: Demographic prisoner's dilemma: A probabilistic framework Abstract: I will present an evolutionary game model based on a multi-agent system. In it the evolution will not be managed by a generation system whereby after play a new population is drawn but instead by the fact that agents who perform poorly will die. Our model represents a spatialized prisoner's dilemma where the players move on a torus and play against other players only if they are at the same location. As it is usually done in evolutionary games, the action of the players will be fixed. A player will be either a cooperative player (who always cooperates) or a defecting player (who always defects). This system has been explored using simulations (or approximations). The presentation will show a probabilistic framework in which we can prove theoretical results. ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Dipartimento di Matematica, Sapienza Università di Roma Martedì 15 novembre Ore 14:00, Aula di Consiglio Seminario di Probabilità e Statistica Matematica Random dynamical systems: contraction and recurrence propertie Marc Peigné, Université de Tours Abstract: Consider a proper metric space X and a sequence (Fn) of i.i.d. random continuous mappings X → X. It induces the stochastic dynamical system (SDS) Xn = Fn ◦ · · · ◦ F1(x) starting at x ∈ X. We study existence and uniqueness of invariant measures, under some assumptions of contraction on the Fn, as well as recurrence and ergodicity of this process. We will consider two main examples: the case where the Fn are affine maps of the real line and the case where Xn is the reflected random walk on the positive real line.

CEMRACS 2017 - Announcement (fwd)
by Tiziano Vargiolu 07 Nov '16

07 Nov '16

********************************************** ** ** CEMRACS 2017 SUMMER SCHOOL ** ** July 17 - August 25 ** MARSEILLE FRANCE ** ********************************************** The 2017 session of the CEMRACS summer school will be held from July 17 to August 25, at CIRM, Luminy (Marseille). This annual summer school on numerical methods has been existing for 20 years. The 2017 session will be dedicated to numerical methods for stochastic problems, including: * control problems, * uncertainty quantification, * mean field models, see the web page of the school for more information: http://smai.emath.fr/cemracs/cemracs17/ The summer school is organized as follows: * The first ten days are dedicated to lectures on numerical methods, including HPC training on computers. * During the next five weeks, Phd or Postdoc students work in groups of 2 or 3 on a numerical project that has been proposed by an industrial or a research department. Specialists of numerical methods and IT will support them. We are currently making three calls: *Call 1. Call 1 is for attending the lectures of the summer school (July 17-26), see the program at http://smai.emath.fr/cemracs/cemracs17/summerschool.html. *Call 2. Call 2 regards the submission of numerical projects: research departments and industrials can submit their own numerical projects. It is a way for them to accelerate the study of a numerical problem or of a numerical method. A project may include students who will work on it, or it may not include students. In the latter case, we will assign students to the project, see Call 3 below. More information is available at http://smai.emath.fr/cemracs/cemracs17/projects.html. Examples from the 2016 edition can be found at http://smai.emath.fr/cemracs/cemracs16/research/conf.php. *Call 3. Call 3 concerns students without a project who would like to work on a project, as defined in Call 2. So, this call is dedicated to Phd students and postdoc students that are not already part of a submitted project. They will be assigned to one of the projects without students (or with not enough students). Projects may end up with a publication, on the underlying numerical method or on some corresponding application. Proceedings will be edited after the event. The registration/accommodation fees are detailed on http://smai.emath.fr/cemracs/cemracs17/. For hosting a project, a participation to global expenses of CEMRACS is asked. For further details, please contact us. Emails should be sent to one of the organizers (see the list below) or at the email address cemracs17(a)smai.emath.fr Could you please circulate the information to colleagues and to industrial contacts that might be interested ?
