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.

Seminario di Franchesca Cottini a Trento
by Michele Coghi 04 Sep '23

04 Sep '23

Cari colleghi, giovedì Francesca Cottini kerrà un seminario presso l'Università di Trento. Trovate tutti i dettagli in calce a questa email. Saluti, Michele Coghi *Luogo:* l'evento si terrà in presenza in *Aula Seminari 1 – PovoZero* – Via Sommarive 14 e per via telematica attraverso collegamento alla *piattaforma Zoom*. Per partecipare sarà necessario collegarsi al link seguente e inserire i codici di accesso (da condividere solo con contatti fidati): https://unitn.zoom.us/j/82578903026 ID riunione: 825 7890 3026 Passcode: 978062 *Data:* Giovedì 7 settembre 2023 *Ore:* 14:30 *Gaussian fluctuations for 2d directed polymers* *Relatrice:* - *Francesca Cottini *(University of Luxembourg e National University of Singapore) *Abstract: * The model of directed polymer in random environment describes a perturbation of the simple random walk caused by a random environment (disorder). In recent years, there has been extensive research on the partition functions of this model and its asymptotic behavior on large scale, also motivated by their link with the solution of the Stochastic Heat Equation. After introducing the model and its motivations, we will focus on the 2d case. We will provide an overview of the main results regarding the fluctuations of the partition functions in both the sub-critical regime (where a deep understanding has by now been obtained) and the critical regime (where many key questions are still open). We will also highlight the distinctions between these observed phenomena. We will then present an alternative and convenient technique to recover both existing and new results. This method is based on a novel CLT for polynomial chaos (i.e. a multi-linear polynomial of independent random variables) which only requires second moment computations. If time allows, we will also discuss the so-called quasi-critical regime, which bridges the gap between the sub-critical and the critical regime and identifies the most extended range where Gaussian fluctuations hold, before reaching the critical regime where they fail. The talk is based on joint works with Francesco Caravenna and Maurizia Rossi (University of Milano-Bicocca). *Referenti: *Stefano Bonaccorsi e Michele Coghi https://webmagazine.unitn.it/evento/dmath/117702/gaussian-fluctuations-for-… [image: Università di Trento] <http://www.unitn.it/> *Staff di Dipartimento-Matematica* Università degli Studi di Trento Via Sommarive, 14 - 38123 Povo (TN) Tel. +39 0461 283898 - Francesca Stanca Tel. +39 0461 281980 - Michela Vinotti Tel. +39 0461 281511 - Davide Bortoli Tel. +39 0461 281625 - Orietta Osele Tel. +39 0461 281701 - Cinzia Parolari -- Dr. Michele Coghi University of Trento, Math Department via Sommarive 14 - 38123 Povo (Trento) - I Povo 0, Room 2.91 E-Mail: michele.coghi(a)unitn.it

Two talks at UniMiB: Marco Carfagnini and Willem Van Zuijlen [7 September]
by Tal Orenshtein 02 Sep '23

02 Sep '23

Dear colleagues, I am glad to announce the following hybrid probability seminar with *two* *speakers* at Milano-Bicocca. Date and time: *Thursday September 7, 10:00-12:00 *(Rome time, zone)*, * *Aula 3014* Building *U5*/RATIO, Univ. *Milano-Bicocca*. Zoom link: https://us02web.zoom.us/j/84444882953?pwd=QkVweTJ4RDJMamN3cjExblViUExMZz09 ID riunione: *844 4488 2953, *Passcode: *835623* *10:00-11:00 Marco Carfagnini (*University of California San Diego) Title: Spectral gaps via small deviations. Abstract: In this talk we will discuss spectral gaps of second order differential operators and their connection to limit laws such as small deviations and Chung’s laws of the iterated logarithm. The main focus is on hypoelliptic diffusions such as the Kolmogorov diffusion and horizontal Brownian motions on Carnot groups. If time permits, we will discuss spectral properties and existence of spectral gaps on general Dirichlet metric measure spaces.This talk is based on joint works with Maria (Masha) Gordina and Alexander (Sasha) Teplyaev. *11:00-12:00 Willem Van Zuijlen* (Weierstrass Institute Berlin) Title: Weakly self avoiding walk in a random potential. Abstract: We investigate a model of simple-random walk paths in a random environment that has two competing features: an attractive one towards the highest values of a random potential, and a self-repellent one in the spirit of the well-known weakly self-avoiding random walk. We tune the strength of the second effect such that they both contribute on the same scale as the time variable tends to infinity. In this talk I will discuss our results on the identification of (1) the logarithmic asymptotics of the partition function, and (2) of the path behaviour that gives the overwhelming contribution to the partition function. This is joint work with Wolfgang König, Nicolas Pétrélis and Renato Soares dos Santos.
