SPASS Seminars: Gigliola Staffilani and Vanessa Jacquier
by Andrea Agazzi 06 Sep '23

06 Sep '23

Dear Colleagues, We would like to invite you to the following (double) SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstracts below): Some recent developments in wave turbulence theory by *Gigliola Staffilani* (MIT) Homogeneous and heterogeneous nucleation in the three-state Blume-Capel model by* Vanessa Jacquier* (University of Utrecht) The seminars will take place on *TUE, 12.9.2023* respectively at *14:00 CET and 15:00 CET *in Aula Seminari, Dipartimento di Matematica, University of Pisa and streamed online at the link below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- Some recent developments in wave turbulence theory Abstract: In this talk I will present two different approaches in the study of wave turbulence theory. The first, introduced by Bourgain, consists in analyzing the long time behavior of high Sobolev norms for the defocusing, cubic NLS equation on 2D tori (periodic solutions). In this context I will emphasize how the rationality or irrationality of the torus affects the analysis. The second approach deals with the rigorous derivation of the 3-wave kinetic equation from a weakly nonlinear multidimensional KdV type equation. Homogeneous and heterogeneous nucleation in the three-state Blume-Capel model Abstract: We study the metastable behavior of the stochastic Blume–Capel model evolving according to the Glauber dynamics with zero boundary conditions. We will show that, due to the three–state character of the Blume–Capel model, the metastability scenario proven for periodic boundary conditions changes deeply when different boundary conditions are considered. The Hamiltonian of the Blume–Capel model depends on the magnetic field h and the chemical potential λ. We study the heuristic in the whole region λ,h > 0, where the chemical potential term equally favors minus and plus spins with respect to zeroes and the magnetic field favors pluses and disadvantages minuses with respect to the zeroes, and we compare our results with the Blume-Capel model with periodic boundary conditions. Then, we analyze in detail the region λ>h > 0. In this region, we identify the unique metastable state -1, we compute the energy barrier from -1 to the stable state +1, and we find an estimate for the asymptotic behavior of the transition time from the metastable to the stable state as β->∞, where β is the inverse of the temperature.

workshop announcement on "SDEs with low-regularity coefficients: theory and numerics" - 21 & 22 Sept, Torino
by Elena Issoglio 05 Sep '23

05 Sep '23

Dear colleagues, This is to announce the workshop on "SDEs with low-regularity coefficients: theory and numerics" <https://sites.google.com/view/singular-sdes2023/home> that will be held at the dept of mathematics in Torino, on 21-22 September 2023. The objective of the meeting is to exchange ideas and recent results in 'singular stochastic analysis'. In particular we study Stochastic Differential Equations with coefficients of low regularity. Such coefficients may be functions or (reasonably well-behaved) distributions. The driving noises can be Gaussian or non-Gaussian (e.g. fractional Brownian motion, Levy process, etc...) and the type of SDE may be a standard forward diffusion, a backward SDE or even a McKean-type SDE. These singular SDEs can be investigated from a theoretical perspective, hence answering fundamental questions such as existence, uniqueness and regularity of the solution, long time behaviour and other features of the solutions. They can also be addressed from a numerical approximation perspective, hence designing numerical schemes and proving their convergence and relative rate of convergence. Invited speakers are: - Mireille Bossy (Inria Sophia Antipolis) - Oleg Butkovsky (Weierstrass Institute Berlin) - Konstantinos Dareiotis (University of Leeds) - Mate Gerencser (TU Wien) - Ludovic Goudenege (CNRS) - Benjamin Jourdain (Ecole des Ponts ParisTech) - Khoa Le (University of Leeds) - Chengcheng Ling (TU Wien) - Stephane Menozzi (University of Evry) - Francesco Russo (ENSTA Paris) - Michaela Szölgyenyi (University of Klagenfurt) The registration is free but mandatory. Deadline for registering is 10th September. Please register here <https://forms.gle/D3D1CKidMGKmcQcG8>. For more info you can contact Elena Issoglio at elena.issoglio(a)unito.it. Feel free to circulate the announcement to anyone who may be interested in this workshop.

International Conference in Venice - CALL FOR PARTICIPATION
by Monica Billio 04 Sep '23

04 Sep '23

*GRETA Associati* (Venice, Italy), *CRIF* (Bologna, Italy), *European Datawarehouse* (Frankfurt, Germany), *European Investment Bank* (Luxembourg),*European Investment Fund* (Luxembourg) and *Intesa Sanpaolo *(Milan, Italy) are partners in organising a Conference to be held in Venice on September 21-22, 2023. The *CREDIT 2023* 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 2023* is the *twenty-second *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*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria*, and *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. /Recent years have seen a series of crises (from health/pandemic to climate/energy) that have not only put a strain on global mechanisms previously seen as robust, but have exacerbated existing weaknesses and so increased vulnerability in new crisis situations. The social impact of the pandemic was partially mitigated by public interventions but social conditions then worsened with the soaring costs of energy, raw materials and inflation more broadly. Social and energy costs, which inevitably weigh on invidual countries and aggravate already delicate local situations (e.g., public debts), have led to growing geopolitical tensions, with global systemic consequences. The CREDIT 2023 conference will be dedicated to Social, Sovereign and Geopolitical Risks to discuss, evaluate and address the near- and medium-term macro-financial impact of persistent crises (“permacrisis”) that can affect the stability of financial as well as socio-economic systems./ The Scientific Committee consists of: *Moritz Schularick* (Sciences Po Paris & University of Bonn, Programme Chair) *Francesca Campolongo* (Joint Research Center, European Commission) *Rajna Gibson* (University of Geneva & Geneva Finance Research Institute) *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)* Loriana Pelizzon* (Ca’ Foscari University of Venice, Leibniz Institute for Financial Research SAFE & Goethe University)* Roberto Rigobon* (MIT Sloan School of Management)* Stephen Schaefer* (London Business School)* Marti Subrahmanyam* (NYU Stern Business School) * Christoph Trebesch* (Kiel Institute)** *PROGRAMME: Click here to see the conference programme <https://www.greta.it/index.php/it/general-information-credit23/programme-20…>* ** **REGISTRATION: Click here to register <https://registration.nexave.org/it/iscrizione-evento/27/22nd-international-…>** For the Registration Fees and more detailed information, please visit the *Conference website <https://www.greta.it/index.php/it/credit-2023>* -- Nota automatica aggiunta dal sistema di posta *Sostieni il futuro* Dona il tuo 5x1000 al Collegio Internazionale Ca' Foscari *FINANZIAMENTO DELLA RICERCA SCIENTIFICA E DELLA UNIVERSITÀ | CODICE FISCALE: 80007720271*

Seminario congiunto di Probabilità e Fisica Matematica a Roma1
by Faggionato, Alessandra 04 Sep '23

04 Sep '23

Buongiorno, il seguente seminario si terrà al Dipartimento di Matematica, Università La Sapienza: *Martedì 12 Settembre, ore **14:00*, *Sala di Consiglio* *Speaker: Armand Bernou (Università di Lione)* *Title: Harris theorems for kinetic models with physical boundary conditions* Abstract: Harris theorems are powerful tools for studying the asymptotic behavior of Markovian models. Originating from the probabilistic literature, they were recently adapted to the PDE framework by Hairer-Mattingly and Cañizo-Mischler. I will present some recent works in which this method furnishes an alternative strategy for treating kinetic models with boundary conditions. I will discuss in particular the long-time behavior of the free-transport kinetic equation and of the linear Boltzmann models when the gas is enclosed in a domain with diffuse or Cercignani-Lampis boundary condition and variable temperature at the wall, which, in general, can not be handled with usual hypocoercivity methods.
