Carissimi, il Dipartimento di Matematica dell'Università di Trento invita gli interessati al seguente seminario: A mean-field model with discontinuous coefficients for interacting neurons *Lunedì 16 aprile 2018* *Luogo*: *Aula seminari (piano terra)* *Dipartimento di Fisica* *Ore*: 15:00 Relatore: - *Giovanni Alessandro Zanco* (IST Wien) Abstract: We propose a new stochastic model for a system of interacting neurons that follow an integrate-and-fire dynamics with interaction that depends on the (random) spatial configuration of neurons and with discontinuous coefficients. We prove strong well-posedness of the resulting system of SDEs and study the mean-field limit as the number of particles tends to infinity. We obtain a Fokker-Planck-type PDE and show that it has a unique weak function-valued solution, obtained as the limit of the laws of the empirical measures for the system of particles. *Referente:* Stefano Bonaccorsi

seminario Silvana Pesenti - 23 aprile 2018
by Emanuela Rosazza 10 Apr '18

10 Apr '18

Si avvisa che il giorno lunedì 23 aprile alle ore 16 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Silvana Pesenti (Cass Business School, City, University of London) Titolo: “Cascade Sensitivity Measures” Abstract: In risk management, an internal model consists of three elements: (i) a random vector of input risk factors, (ii) a real valued aggregation function, and (iii) the output, which is a random variable obtained by applying the aggregation function to the vector of risk factors. Sensitivity analysis often requires evaluation of changes in the distribution of the output, when the distribution of risk factors is varied with reference to a baseline input distribution. We introduce a novel sensitivity measure termed cascade sensitivity, which quantifies the extent to which small changes (stresses) in an individual risk factor affect the output risk measure. The proposed method captures the direct impact on the output, as well as indirect effects via other risk factors that are dependent with the one being stressed. In this way, the dependence between risk factors is explicitly taken into account. Alternative representations of the cascade sensitivity measure are provided, requiring either knowledge of the aggregation function's gradient or additional evaluations of the model under alternative distributional assumptions. This is of particular interest in applications, where the distribution of the output is typically determined via simulation methods. Furthermore we give a representation of the proposed sensitivity measure that can be calculated from a single simulated sample starting from the baseline model, without the need to simulate under a different model specification or to explicitly study the properties of the aggregation function. This makes the proposed method attractive for practical applications, as is illustrated through numerical examples. Joint work with Pietro Millossovich and Andreas Tsanakas. Tutti gli interessati sono invitati a partecipare. Un saluto cordiale, Emanuela ******************************************************************************************* Emanuela Rosazza Gianin Dipartimento di Statistica e Metodi Quantitativi Università di Milano-Bicocca Edificio U7 – 4° Piano Via Bicocca degli Arcimboldi, 8 20126 Milano Tel. 02 64483208 Fax. 02 64483105 e-mail: emanuela.rosazza1(a)unimib.it *******************************************************************************************

Advanced School on complexity and emergence: second announcement
by elisa mastrogiacomo 10 Apr '18

10 Apr '18

This is the *second** announcement* of the upcoming *Advanced School on complexity and emergence: ideas, methods, with a special attention to economics and finance (CEIM)* The School will be held in the magnificent Villa del Grumello, Como (Italy) along the Lake Como shore on July 22-27, 2018. The main courses will be given by L. Boi (EHESS – Paris), I. Capelli (Università dell’Insubria), I. Ekeland (Ceremade - Universitè Paris-Dauphine), F. Guerra (Sapienza Università di Roma), J. Jost (Max Planck Institute for Mathematics in the Sciences - Leipzig), Florent McIsaac, (Agence Française pour le Développement), F. Patras (Université de Nice Sophia-Antipolis), F. Riedel (Center for Mathematical Economics, Bielefeld University), F. Semboloni (Università degli studi di Firenze), R. Seri (Università dell’Insubria). The potential participants of the School are primarily master and doctorate students of mathematics, information sciences, theoretical physics, and economics, as well as research workers in those areas, who want to enlarge their spectrum of knowledge towards the area of complexity. The aim of the School is to provide these researchers useful instruments from the theory of complex systems, both on the theoretical level and the methodological ones, bridging the present disciplinary gap, and profiting from knowledge and insights from both communities. The School may have some (limited number of) financial supports. Details about the registration, the application for financial support are available at the website http://ceim.lakecomoschool.org/. We would be grateful if you could circulate this announcement among your PhD students, postdocs and colleagues. With our best regards, Sergio Albeverio Elisa Mastrogiacomo Fabio Minazzi Emanuela Rosazza Gianin Stefania Ugolini

Seminario congiunto di Fisica Matematica e Probabilita' a Roma1
by Faggionato, Alessandra 09 Apr '18

09 Apr '18

Mercoledì 18 aprile, ore 16:30, aula di Consiglio, Dipartimento di Matematica, La Sapienza. Speaker: Fabio Toninelli (Université Lyon 1) *Title: Lozenge tiling dynamics and hydrodynamic equation* Abstract: We study a reversible continuous-time Markov dynamics on lozenge tilings of the torus, introduced by Luby et al. Single updates consist in concatenations of n elementary lozenge rotations at adjacent vertices, with rate 1/n. The dynamics can also be seen as a reversible stochastic evolution of a 2+1-dimensional interface. The dynamics is known to enjoy especially nice features: a certain Hamming distance between configurations contracts with time on average and the relaxation time of the Markov chain is diffusive. We present another remarkable feature of this dynamics, namely we derive, in the diffusive time scale, a fully explicit hydrodynamic limit equation for the height function (in the form of a non-linear parabolic PDE). The mobility coefficient μ in the equation has non-trivial but explicit dependence on the interface slope and, interestingly, is directly related to the system’s surface free energy. The derivation of the hydrodynamic limit is based on the so-called H^{-1} method due to Yau and Funaki-Spohn. Based on joint work with Benoit Laslier (Paris 7). -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************
