Seminario di J. Moller al Politecnico di Milano, Mercoledì 9 ottobre
by Mario Beraha 25 Sep '24

25 Sep '24

Buongiorno a tutti, Vi segnalo il seguente seminario in presenza presso il Politecnico di Milano. Il seminario verrà erogato anche in modalità on-line al seguente link https://polimi-it.zoom.us/j/98526429718 9/10/2024, ore 10:00, Aula Saleri 6° Piano, Edifico 14 “La Nave”, campus Leonardo, via Edoardo Bonardi 9, 20133 Milano. Speaker: Jesper Moller, Aalborg University Titolo: The sufficient digits of continuous random variables Abstract: A general setting for nested subdivisions of a bounded real set into intervals defining the digits X_1,X_2, ... of a random variable X with a probability density function f is considered. Under the weak condition that f is almost everywhere lower semicontinuous, a coupling between X and a non-negative integer-valued random variable N is established so that X_1, ...,X_N have an interpretation as the “sufficient digits”, since the distribution of (X_{N+1}, X_{N+2}, ...) conditioned on (X_1, ...,X_N) does not depend on f. The importance of this coupling result and some suggestions and open problems for future research are discussed.

Seminario a Roma1, Mercoledì 25 Settembre
by Faggionato, Alessandra 24 Sep '24

24 Sep '24

Buongiorno ricevo e con piacere inoltro. Saluti Alessandra ---------- Forwarded message --------- From: Basile, Giada <basile(a)mat.uniroma1.it> Seminari di Fisica Matematica Dipartimento di Matematica "G. Castelnuovo" Università di Roma La Sapienza Mercoledì 25 settembre, ore 16:00, sala di Consiglio Heide Langhammer (WIAS, Berlin) *Large deviations for a spatial particle process with coagulation* Abstract. In this talk we consider a spatial version of the Marcus-Lushnikov process, which models the evolution of particles that merge pairwise in a series of coagulation events. The particles are equipped with a spatial location and an integer mass. In a coagulation event a pair of particles is merged and replaced by a new particle. The mass of the newly formed particle is the sum of the former two and its location is sampled according to a given distribution. The exponential rate of a coagulation event depends on the locations and masses of the particle pair via a coagulation kernel. For the non-spatial version of this model it is known that certain kernels exhibit a gelation phase transition, which describes the formation of one or several large particles after a finite time. In this talk we introduce a new approach for studying the process. We will provide a formula that connects its distribution to a Poisson point process and show how this can be used to derive a large deviation principle. From this we gain new insights into the limiting behavior of the process and obtain criteria for the gelation phase transition. Tutte le persone interessate sono invitate a partecipare. Il seminario si svolgerà all'interno delle attività del progetto PRIN 202277WX43 "Emergence of condensation-like phenomena in interacting particle systems: kinetic and lattice models" finanziato dall’Unione europea – Next Generation EU. -- ************************************************* Prof. Alessandra Faggionato https://www1.mat.uniroma1.it/people/faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 123, first floor *************************************************

International Conference in Venice on AI, digital and sustainability transitions - CALL FOR PARTICIPATION
by Monica Billio 19 Sep '24

19 Sep '24

23nd INTERNATIONAL CONFERENCE CREDIT 2024 *The frontiers of new risks: AI, digital and sustainability transitions * Venice, Italy 3 – 4 October 2024 * * *GRETA Associati* (Venice, Italy),*CRIF* (Bologna, Italy), *European Datawarehouse *(Frankfurt am Main, Germany), *European Investment Fund* (Luxembourg), *Intesa Sanpaolo* (Milan, Italy) and *Modefinance* (Trieste, Italy) are partners in organising a Conference to be held in Venice on October 3-4, 2024. * * The CREDIT 2024 conference will bring together academics, practitioners and PhD students working in various areas of financial and socio-economic risk with the aim of creating a unique opportunity for participants to discuss research progress and policy as well as industry-relevant insights and directions for future research. CREDIT 2024 is the *twenty-third* in a series of events dedicated to various aspects of credit risk and organised under the auspices of: the *Department of Economics *and*VERA - Venice centre in Economic and Risk Analytics for public policies* - of the *Ca’ Foscari University of Venice*,*Joint Research Center European Commission*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria*, *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. Sustainability necessarily involves the adaptation of today’s business model to the dynamic nature of the current digitalised environments. Corporations need to make sure that resources, especially technology, are being used responsibly and efficiently to improve the lives of the present generations and future generations as well as strengthen their relationships with the environment as to solve sustainability-related problems such as poverty, environmental degradation, pollution and inequality. Artificial Intelligence (AI) has the potential to address these societal problems including sustainability. The climate crisis and the degradation of the physical environment are complex problems that require the most innovative and advanced solutions. The real value of AI hence lies in its ability to facilitate and foster environmental and social governance, rather just as a tool to reduce pollution, poverty and resource depletion. In the age of AI, societies depend on big data, social media, knowledge management and data science to survive and achieve these sustainability goals. AI has the potential to reshape not only finance and industry but also the whole society. There is need to understand opportunities and challenges as to properly manage all relevant risks. The SCIENTIFIC COMMITTEE for the Conference consists of: *Marcin Kacperczyk *(Imperial College London, Programme Chair) *Monica Billio* (Ca’ Foscari University of Venice & GRETA) *Marie Brière* (AMUNDI & Université Libre de Bruxelles) *Lucia Alessi* (Joint Research Center, European Commission) *Leonardo Gambacorta *(Bank For International Settlements) *Mila Getmansky Sherman* (Isenberg School of Management, UMass Amherst) *Christian Gollier* (Toulouse School of Economics) *Helmut Kraemer-Eis *(European Investment Fund) *Jan Pieter Krahnen *(Leibniz Institute for Financial Research SAFE & Goethe University) *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven, NTNU Business School & CEPR) *Roberto Rigobon *(MIT Sloan School of Management) *Stephen Schaefer* (London Business School) *Marti Subrahmanyam *(NYU Stern Business School) *PROGRAMME:* https://www.greta.it/index.php/it/general-information-credit24/programme-20… *REGISTRATION*: https://registration.nexave.org/it/iscrizione-evento/32/23rd-international-… For the Registration Fees and more detailed information, please visit the Conference website: https://www.greta.it/index.php/it/credit-2024 *ACKNOWLEDGEMENT OF EUROPEAN FUNDING* The organization of the conference has benefitted from financial support by: - the European Union – Next Generation EU, Mission 4 Component 2, as part of the *GRINS project - Growing Resilient, INclusive and Sustainable* (code: PE0000018, CUP: H73C22000930001) - National Recovery and Resilience Plan (PNRR) - *ESG UPTAKE — TSI-2023-ESGRM-IBA* - ESG risk management framework for the financial sector.

ABSTRACTS ____________________________________________ SPEAKER: Prof. Marielle Simon (Université Lyon 1) TITLE: ``On exclusion processes with phase separation" ABSTRACT: "Stochastic lattice gases" are models of interacting particles subject to stochastic dynamics. They have been widely studied for about thirty years by both mathematicians and physicists. Their structure makes it possible to analyse them rigorously, while illustrating numerous physical phenomena: in particular, one of the main objectives is to prove rigorously the convergence of the microscopic system towards a macroscopic PDE, after rescaling in time and space (also known as the ‘hydrodynamic limit’). In the first lecture I will give several illustrations of this convergence result thanks to the most well-known example, namely the symmetric simple exclusion process. In the second lecture, I will show how to enrich these models in order to derive some phase separation at the macroscopic level, with a free boundary that moves within the system. SPEAKER: Prof. Michel Mandjes (Leiden University) TITLE: Dynamic random graphs: analysis and inference ABSTRACT: The bulk of the random graph literature concerns models that are of an inherently static nature, in that features of the random graph at a single point in time are considered. There are strong practical motivations, however, to consider random graphs that are stochastically evolving, so as to model networks’ inherent dynamics. In this talk I’ll discuss a set of dynamic random graph mechanisms and their probabilistic properties. Key results cover functional diffusion limits for subgraph counts (describing the behaviour around the mean) and a sample-path large-deviation principle (describing the rare-event behaviour, thus extending the seminal result for the static case developed by Chatterjee and Varadhan). The last part of my talk will be about estimation of the model parameters from partial information. We for instance demonstrate how the model’s underlying parameters can be estimated from just snapshots of the number of edges. We also consider settings in which particles move around on a dynamically evolving random graph, and in which the graph dynamics are inferred from the movements of the particles (i.e., not observing the graph process).
