15 Sep '23

Si avvisa che in data 21-09-2023, alle ore 14:30 precise presso il Politecnico di Milano, in aula 16B.2.1, nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Sesia Matteo, University of Southern California Titolo: Adaptive conformal classification with noisy labels Abstract: This work develops novel conformal prediction methods for classification tasks that can automatically adapt to random label contamination in the calibration sample, enabling more informative prediction sets with stronger coverage guarantees compared to state-of-the-art approaches. This is made possible by a precise theoretical characterization of the effective coverage inflation (or deflation) suffered by standard conformal inferences in the presence of label contamination, which is then made actionable through new calibration algorithms. Our solution is flexible and can leverage different modeling assumptions about the label contamination process, while requiring no knowledge about the data distribution or the inner workings of the machine-learning classifier. The advantages of the proposed methods are demonstrated through extensive simulations and an application to object classification with the CIFAR-10H image data set.

seminario SMS - Trevisani (Universitade da Coruña and CITIC)
by Elena Issoglio 13 Sep '23

13 Sep '23

Cari colleghi, vi segnalo il prossimo seminario della serie Stochastics and Mathematical Statistics (SMS) https://sites.google.com/view/torinostochastics/home-page *Data:* *Mer 20 Settembre *alle ore* 14.00-15.00* *Luogo*: *Aula C*, Palazzo Campana, Via Carlo Alberto 10, Torino *Speaker:** Davide Trevisani* (Universitade da Coruña and CITIC) *Titolo*: A brief introduction to XVA and KVA *Abstract**: * Differently from some financial asset classes whose risks can belong to a wide market segment, many derivatives are closely tied to counterparty risk. Already at the end of ’90s, and definitively with the great crisis of 2007-2008, quantifying such risk gained great importance in financial industry. However, nowadays, institutions are not merely concerned with coping with default events but also with the expenses associated with such risks. These expenditures are primarily driven by regulatory requirements and contractual obligations. Quantifying these costs is the aim of Value Adjustments (XVAs). In this talk, we briefly present the mathematical framework of market with dividends. We then examine a pricing model with KVA (Capital Value Adjustment). Si invitano tutti gli interessati a partecipare. Cordialmente Elena (a nome degli organizzatori Bruno Toaldo, Elena Issoglio) *----------------------------------------------* *Dr Elena Issoglio* *Assistant Professor in Probability **(RTD-B)* *Department of Mathematics "G.

DEMS Bicocca Statistics seminar - Victor M. Panaretos - September 27th at 12 pm
by Alessia Caponera 13 Sep '23

13 Sep '23

Dear colleagues, We are pleased to announce the seminar of Victor M. Panaretos (EPFL), on *Wednesday the* *27th of September at 12:00 pm*, at the University of Milano-Bicocca, Department of Management, Economics, and Statistics (DEMS). The seminar will be held in presence at the DEMS seminar room 2104 (building U7 Civitas, 2nd floor). ******************************************************* *Time: *Wednesday September 27th, at 12:00 pm *Place: *University of Milano-Bicocca | DEMS | Room 2104 (building U7 Civitas, 2nd floor) *Title: *Graphical Models for Stochastic Processes *Speaker:* Victor M. Panaretos (Institute of Mathematics, EPFL) *Abstract:* Graphical models allow us to distinguish direct and indirect associations in data. They can be used as models or they can be the targets of inference, and have been extensively studied in many contexts, the most recent emphasis being in high-dimensional statistics. For the most part, one considers a collection of random vectors indexed by a finite or discrete set. The purpose of this talk is to explore what happens when we are interested in the associations within and between stochastic processes. In the first case, we are dealing with graphical models with uncountable rather than discrete index set. In the latter case, we are dealing with graphical models for finite collections of function-valued random variables. Such settings introduce conceptual challenges owing to the lack of infinite-dimensional analogues of familiar algebraic tools, such as matrix inverses and determinants. It will turn out that the two problems share commonalities but also notable differences. Based on joint work with Kartik Waghmare (EPFL) and Tomas Masak (EPFL). ******************************************************* Best wishes, Alessia Caponera

SPASS Seminars: Giuseppe Cannizzaro and Giacomo di Gesù
by Francesco Grotto 13 Sep '23

13 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): *Weak coupling scaling of critical SPDEs* by *Giuseppe Cannizzaro *(University of Warwick) *Sharp asymptotics for the Allen-Cahn equation in the limit of small noise and large volume* by* Giacomo di Gesù* (La Sapienza) The seminars will take place on *TUE, 19.9.2023* 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…> -------------------------------------------- *Weak coupling scaling of critical SPDEs* Abstract: The study of stochastic PDEs has known tremendous advances in recent years and, thanks to Hairer's theory of regularity structures and Gubinelli and Perkowski's paracontrolled approach, (local) existence and uniqueness of solutions of subcritical SPDEs is by now well-understood. The goal of this talk is to move beyond the aforementioned theories and present novel tools to derive the scaling limit (in the so-called weak coupling scaling) for some stationary SPDEs at the critical dimension. Our techniques are inspired by the resolvent method developed by Landim, Olla, Yau, Varadhan, and many others, in the context of particle systems in the supercritical dimension and might be well-suited to study a much wider class of statistical mechanics models at criticality. *Sharp asymptotics for the Allen-Cahn equation in the limit of small noise and large volume* Abstract: We consider the Allen-Cahn equation on a finite interval perturbed by space-time white noise. Keeping the size of the spatial domain fixed, the dynamics becomes metastable in the limit of vanishing noise. I will review some sharp metastability estimates in this regime and discuss how the invariant measure and long-time behavior is affected if one allows the system size to grow while the noise vanishes (joint work with L. Bertini and P. Buttà).

UNIVERSITA' DI SALERNO Dipartimento di Matematica *AVVISO** DI SEMINARIO* La Prof.ssa *Giulia DI NUNNO* (University of Oslo, Department of Mathematics) mercoledì 13 settembre, alle ore 13:00, presso la Sala Riunioni dell'Edificio F2 (piano 1, stanza 36), terrà un seminario dal titolo: *Sandwich volatility modelling and hedging* Gli interessati sono cordialmente invitati a partecipare, *Antonio Di Crescenzo* *Barbara Martinucci* *Alessandra Meoli**Serena Spina* Link su Teams: https://teams.microsoft.com/l/meetup-join/19%3ameeting_OTcwY2Q1ZDktYmIyMS00… *Abstract* Sandwiched Volterra Volatility (SVV) models are a class of models able to capture both the long memory and the rough aspects of volatility. We present the structure and the properties. We then move to consider hedging and consider the explicit computation of quadratic hedging strategies. the theoretical solution is well-known in terms of the non-anticipating derivative for all square integrable claims, the fact that these models are typically non-Markovian provides a concrete difficulty in the direct computation of conditional expectations at the core of the explicit hedging strategy. To overcome this difficulty, we propose a Markovian approximation of the model which stems from an adequate approximation of the kernel in the Volterra noise. We show some numerical simulations performed with different methods.

A ‘replicability crisis’ has been claimed in the last decades, denouncing that a large part of published research findings, especially in applied sciences, such as psychology or medicine failed to be confirmed by subsequent studies. Difficulties in moving from empirical evidence and data analysis to a scientific result push towards the need to clarify various aspects, such as rigorous definitions, the possible tools for understanding and communicating the uncertainty inherent in most scientific conclusions, the definition of non-questionable research practices.

SPASS Seminars: Gigliola Staffilani and Vanessa Jacquier

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.

Premio de Finetti e seminario vincitore Conferenza UMI
by Claudia Ceci 05 Sep '23

05 Sep '23

Buonasera a tutt*, vi comunico che il PREMIO BRUNO de FINETTI 2023 (Premio UMI, Profilo A destinato a matematici che abbiano dato rilevanti contributi nel campo del Calcolo delle Probabilità e delle sue applicazioni) è stato conferito a Jacopo Borga. Si riporta un breve estratto del verbale della commissione giudicatrice: "Dopo lunga e approfondita discussione, decide all’unanimità di assegnare il Premio “Bruno de Finetti” 2023, a *Jacopo BORGA*. Tra i candidati che hanno presentato domanda, a parere della Commissione, meritano una menzione speciale i seguenti nominativi (in ordine alfabetico): Giorgio Ferrari, Maurizia Rossi e Bruno Toaldo." Giovedì 7 settembre, a Pisa, nello spazio del Congresso UMI dedicato ai Gruppi UMI, dalle 16:35 alle 17:05, nell'Aula 1 del Polo Carmignani, Jacopo BORGA terrà il seguente seminario: TITOLO: Geometria dei meandri aleatori ABSTRACT: Nel 1912, Henri Poincaré pose la seguente domanda: "In quanti modi una curva semplice chiusa, chiamata meandro, può attraversare una retta in un numero prefissato di punti?". Nonostante vari sforzi, questa domanda rimane ancora aperta dopo più di un secolo. Presenterò una nuova congettura per il limite di scala di un meandro aleatorio uniforme e discuterò alcuni recenti risultati che vanno nella direzione di dimostrare tale congettura. Il colloquio sarà basato su un lavoro con Ewain Gwynne e Xin Sun. Tutti gli interessati sono invitati a partecipare.

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.
