Ricevo ed inoltro Saluti Alessandra ---------- Forwarded message --------- Da: Phd Mathematics GSSI <phd.math(a)gssi.it> Date: gio 16 mar 2023, 12:34 Subject: New Call for Math GSSI PhD applications 2023/24 Now open To: *11 PhD FELLOWSHIPS IN MATHEMATICS @GSSI* (Apologies for multiple posting) Please diffuse this announcement among colleagues and potentially interested students. Deadline *May 2nd, 2023 3pm* (Italian time). *Should you require any assistance with questions that are not addressed in the GSSI website*, please contact applications(a)gssi.it ================================================================== Dear Colleagues, this is to announce the opening for *11 PhD Fellowships* in "Mathematics in Natural, Social and Life Sciences" at Gran Sasso Science Institute (GSSI) starting in November 2021. The application must be submitted through the online form available at www.gssi.it/phd/ by May 2nd, 2023 at 3pm (Italian time zone). Please find the call at https://applications.gssi.it/applications/. The fellowships are awarded for 4 years and their yearly amount is € 16.159,91 gross. All PhD students have free accommodation, free luncheon vouchers and use of the canteen. The official language for the PhD course is English. 1 PhD Fellowship is funded under the ERC project *"CARDIOTRIALS -CARDIac simulations to run in-silicO clinical TRIALS**"*, please find further information below. Within the Ph <https://gssi.it/education/mathematics-education>.D. <https://gssi.it/education/mathematics-education>course in Mathematics in Natural, Social and Life Sciences <https://gssi.it/education/mathematics-education> a priority has been established on mathematical modeling, both towards the traditional areas of application, such as Physics or Engineering, and towards emerging issues in Biology and Social Sciences. GSSI mathematics researchers are interested in tackling many problems with complementary perspectives and methods. The area of Mathematics is characterized by four large macro-sectors: Applied Partial Differential Equations, Stochastic Analysis, Numerical methods and Continuum Mechanics Modeling. Within these sectors there is a shared interest in problems related to fluid dynamics and nonlinear waves, quantum mechanics, statistical mechanics and also its applications to data science. Important ideas of classical analysis, probability theory, mathematical physics and theoretical physics are used also for less traditional applications. Numerical linear algebra and numerical optimization help to design new models and accompanying numerical algorithms for applications in data mining, machine learning and network science. Continuum mechanics models, computational methods in fluid dynamics are used not only in their traditional field at the boundary between applied mathematics and theoretical engineering, but also in nonconventional problems like modeling the full heart function. Students and researchers in Mathematics at GSSI are encouraged to interact with other scientific communities. At GSSI, we believe that the interdisciplinary endeavor is the most effective way to do science and benefit society. Mathematical models are ubiquitous in physics, engineering, information theory, social and life sciences, as they provide a formidable framework to describe the time evolution of deterministic, stochastic and complex systems, which is one of the main goals at GSSI. *1 PhD fellowship* funded under the ERC project *“CARDIOTRIALS -CARDIacsimulations to run in-silicO clinical TRIALS**”*. The project aims at building a virtual model of the human heart based on the fluid-structure-electrophysiology interaction, which will be exploited to study numerically pathologies and assess the efficacy of cardiac devices, accounting for the statistical variability of the population. The project comprises the study of fluid dynamics phenomena and the application of numerical mathematics and high performance computing. The candidates willing to apply are required to work on this specific research project. Within the Ph.D. Programme in Mathematics in Natural, Social and Life Sciences, it is possible to apply both for the CardiOTrials Project position and for GSSI scholarships, by submitting two different applications.

Seminario di Marta Leocata, Martedì 21 Marzo, Sapienza Università di Roma
by Silvestri, Vittoria 16 Mar '23

16 Mar '23

Segnalo il seguente seminario, che si terrà Martedì prossimo in Sapienza. *Martedì 21 Marzo, ore 14:00* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Marta Leocata, SNS *Title: *Modeling an example of green transition *Abstract:* The work presented is part of a collaboration between mathematicians and philosophers of ethics, politics, and society aiming to understand mechanisms of green energy transition where some kind of interaction between many subjects and collective behaviors seem to play a role. We have identified as a first example the case of solar photovoltaic, with the purpose of explaining the time series of Italy and of different regions. We use tools from continuous-time Markov chains, mean field limits, optimal control, and mean field games. Then, we specify our analysis on the case of domestic installations. In order to explain them we propose a Markovian model of interacting particle systems to describe the decision of a significant proportion of the general public in Italy on the installation of solar photovoltaics (PVs) and compare our models to real data. We assume that the adoption decision follows a well precise pattern. First, the general public develops a certain level of sensitivity to climate change and environmental issues. Then it plans to install the PVs because she/he has a sufficient amount of information on the benefits of PVs. Finally, it installs PVs because the economic benefits out-weights the costs. In conclusion, we propose some original policies, not based not on financial incentives. This work is in collaboration with Franco Flandoli (SNS), Giulia Livieri (SNS), Silvia Morlacchi (SNS), Fausto Corvino (University of Gothenburg) and Alberto Pirni (SSSA). ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 16 Mar '23

16 Mar '23

22nd INTERNATIONAL CONFERENCE C.r.e.d.i.t. 2023 *Social, Sovereign and Geopolitical Risks * Venice, Italy 21 –22 September 2023 * * *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 organasing a Conference to be held in Venice on September 21-22, 2023. The C.r.e.d.i.t. 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. The C.r.e.d.i.t. 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 C.r.e.d.i.t. 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 organizers encourage submissions on any topic within the overall theme of the conference and in the following areas in particular: * *Socio-economic Stability: *Future development of income (and wealth) inequality and social polarization; Risk, inequality and employment impacts of crises and policies; Gender and skilling issues will increase or help the transition?; * *Sovereign Risks: * Sovereign debt with low economic growth; Long term challenges for fiscal and monetary policies: green transformation, commodity prices, de-globalization and demographic trends; Inflation and exchange rate risks; Environmental and social inter-dependencies; social and environmental preferences and how these affect the stability and macroeconomic wellbeing of a given country; Challenges in measuring the ESG ratings of countries and thus of sovereign debt; * *Geopolitical Risks:* Global supply chain and de-globalization risks for finance; Do international energy price discrepancies pose risks for the competitiveness of EU firms’ and might this have implications for the real exchange rate to?; Risks stemming from accelerating deglobalisation; Cyber-risk vulnerabilities of banks and firms; * *Energy/Commodity Security:* Energy prices and financial performance of firms; Inefficiency of energy markets under scarcity; Transition costs under high energy and resource prices; Volatility of energy-related asset prices (both brown and green) and implications for medium and long term investments in energy production technologies, energy commodity assets and energy infrastructure; Implications of net zero policies for the prices of real estate assets, especially for homeowners and households; * *Long Run Investments and Portfolios:* Stability of asset market equilibria under low returns; Regulation (-demand) driven asset prices; Equilibrium asset price levels under structural transformation and high uncertainty; Net zero pledges and the possible trade-off between sustainability and returns; Engagement versus divesting. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Helen Rey* (London Business School), *Elisa Giuliani *(University of Pisa) and *Moritz Schularick *(Sciences Po Paris & University of Bonn). The Conference will also include panel discussions on the major issues at stake with the views of researchers', practitioners' and policy makers. The SCIENTIFIC COMMITTEE for the Conference 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) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *May 31, 2023 *to the address given below (preferably in electronic format).

Seminar by Yacine Ait Sahalia in Verona, Monday 20/3/2023 at noon: How and When are High-Frequency Prices Predictable?
by Cecilia Mancini 15 Mar '23

15 Mar '23

Dear all, Professor Yacine Ait Sahalia, from Princeton University, will give the seminar How and When are High-Frequency Prices Predictable? on Monday 20/3/2023 at the Department of Economics of the Verona University, at 12 p.m. in sala Vaona, 1st floor, Santa Marta main building, via Cantarane 24, Verona It will be possible to attend the seminar also on zoom (the meeting ID is given at the official page https://www.dse.univr.it/?ent=seminario&id=5807) All interested people will be very welcome. Best regards, Cecilia Abstract: This paper studies the predictability of ultra high-frequency stock returns and durations to relevant events, using machine learning methods. We find that, contrary to low frequency and long horizon returns, where predictability is rare and inconsistent, predictability in high frequency returns and durations is large, systematic and pervasive. We identify the relevant predictors and examine what determines the variation in predictability across different stocks and market environments. Next, we compute how the predictability varies with the timeliness of the data on a scale of milliseconds. Finally, we determine the value of getting a (short-lived and imperfect) peek at the incoming order flow, an ability that is often attributed to the fastest high frequency traders, in terms of improving the predictability.

OWPS Tomorrow: Amandine Veber and Apolline Louvet
by Alberto Chiarini 14 Mar '23

14 Mar '23

Dear all, A reminder that tomorrow (Wednesday), from 15:00 to 17:00 UTC, Amandine Veber (Université Paris Cité) and Apolline Louvet (University of Bath) will be speaking at the One World Probability Seminar. Title, abstract and the zoom link are below the signature and can be found on the website https://www.owprobability.org/one-world-probability-seminar. We kindly ask that you share this message within your community. With best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ----------------------------------------------------------------------------------------------------------- Talk 1 : Amandine Veber (Université Paris Cité) Title : Modelling the evolution of genetic diversity in a population living in a spatial continuum Abstract : The spatial structure of a population influences the way genes are transmitted from one generation to the next, and consequently how the genetic diversity in the population evolves through time. To model this evolution when the population lives in continuous space (a forest, a mountain range, ...), a stochastic process called the spatial Lambda-Fleming-Viot process was introduced in 2008 by Alison Etheridge (Oxford Univ.) and Nick Barton (IST Austria), and has been developed in a various directions since then. We shall review some of the results obtained thanks to this approach, and related questions that are still open. Talk 2 : Apolline Louvet (University of Bath) Title : Constructing a stochastic population genetics process for populations expanding in a spatial continuum Abstract : Spatial Lambda-Fleming Viot processes, or SLFVs, are a family of models for the evolution of genetic diversity in populations living in a spatial continuum. Their main characteristics is their "event-based" reproduction dynamics and the assumption that the area occupied is constant over time. In this talk, I will show how the SLFV modelling framework can be extended to include spatially expanding populations. In order to do so, I will introduce one possible approach to construct SLFVs formally, which is a variant of the method introduced in 2015 by Amandine Véber (Univ. Paris Cité) and Anton Wakolbinger (GU Frankfurt). This approach makes it possible to couple SLFV processes and explore new limiting regimes.

Friday, March 17th 11.30 - 12.30 Luiss | Viale Romania, 32 | Room 310 Arkadi Predtetchinski (Maastricht University) 0-1 Laws for a Control Problem with Random Action Sets In many control problems there is only limited information about the actions that will be available at future stages. We introduce a framework where the controller sequentially chooses actions a0, a1, ... one at a time. Her goal is to maximize the probability that the infinite sequence a0, a1,... is an element of a subset G of the set of infinite sequences of natural numbers. The set G is assumed to be a Borel tail set. The controller's choices are restricted: having taken a sequence ht of actions prior to stage t, she must choose a decision at stage t from a restricted set A(ht) of natural number. The set A(ht) is chosen randomly from a distribution pt, independently over all time periods and past histories. We consider several information structures defined by how far into the future the controller knows what actions will be available. In the special case where all the action sets are singletons (and thus the controller is a dummy), Kolmogorov’s 0-1 law says that the probability for the goal to be reached is 0 or 1. We construct a number of counterexamples to show that in general the value of the control problem can be strictly between 0 and 1, and derive several sufficient conditions for the 0-1 "law" to hold.

SPASS Seminar: Avi Mayorcas

10 Mar '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: Blow-up criteria for an SPDE model of chemotaxis Avi Mayorcas (TU Berlin) The seminar will take place on TUE, 14.3.2023 at 14:00 CET in Sala Seminari, Dipartimento di Matematica, 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 -------------------------------------------- *Abstract: **Chemotaxis and related phenomena have been an active area of mathematical research since statistical and PDE models were first proposed by C. Patlak (’53) and E. Keller & L. Segel (’71). They are commonly studied through mean field PDE models and a common feature of these equations is the possibility of finite time blow-up under given model parameters. Recently it was shown that advection by a sufficiently strong relaxation enhancing vector field could suppress this blow up (Kiselev & Xu ’16, Iyer, Zlatos & Xu ’20). In this talk I will discuss new results (obtained with M. Tomašević) regarding criteria for the persistence of blow-up for an SPDE model of chemotaxis with stochastic advection. The noise we cover is of a form recently shown to be almost surely relaxation enhancing (Gess & Yaroslavtsev ’21) and closely related to those studied in recent works by Galeati, Flandoli and Luo.*

Care Colleghe, cari Colleghi, Segnalo che la prossima call Horizon Europe (HE) dedicata all’Azione Marie Sklodowska-Curie Postdoctoral Fellowships (MSCA-PF) si aprirà il 12 aprile con scadenza il 13 settembre 2023. Le Postdoctoral Fellowships sono finanziamenti indirizzati a sostenere i progetti di giovani ricercatrici e ricercatori eccellenti, che lavorino in collaborazione con un docente Supervisor presso la Host Institution selezionata. Si rivolgono a scienziate e scienziati in possesso del titolo di dottore di ricerca da non più di otto anni. Iniziato nel 2021, il Programma HE ha visto un’attiva partecipazione dell’Ateneo, che ha conseguito ottimi risultati per numero di fellowship assegnate: nell’ultima call 2022, i cui esiti sono stati annunciati in questi giorni (All. 3 - Report Unipd – MSCA 2022), risultano 15 le proposte vincitrici e 13 quelle al momento collocate in lista di riserva. Dal 2014, nell’ambito dei programmi quadro Horizon 2020 e Horizon Europe, sono in totale 106 le ricercatrici e i ricercatori che hanno ottenuto una borsa Marie Skłodowska Curie con l’Università di Padova. Il report allegato illustra il numero di Dipartimenti coinvolti nelle candidature (Report Unipd – MSCA 2022). Tale successo si deve certamente anche alle iniziative promosse dall’Università che sostengono l’Azione, quali la MSCA MaRaThoN - Master your Research and Training Needs, un corso intensivo di preparazione alla scrittura di una proposta progettuale, che intende portare a Padova aspiranti Fellow di talento. Dal 2021, in HE, sono 21 le ricercatrici e i ricercatori partecipanti alla MSCA MaRaThoN ad aver ottenuto una fellowship e 15 ad aver ottenuto il riconoscimento “Seal of Excellence”. La nuova edizione del percorso formativo, che verrà organizzata in presenza dal 22 al 24 maggio 2023, è aperta a 40 potenziali "postdoctoral fellows" selezionati in base ai loro CV e proposal summary. L’Università sosterrà le spese di viaggio e alloggio alle candidate e ai candidati selezionati. Per partecipare, le interessate e gli interessati devono rispettare le condizioni di ammissibilità stabilite dal programma HE MSCA-PF (quali il possesso del titolo di dottore di ricerca da non più di otto anni) e la regola di mobilità indicata dalla call. Il termine per la presentazione delle candidature MSCA MaRaThoN è fissato alle ore 13.00 di martedì 4 aprile 2023. Tutte le informazioni sono disponibili al link https://www.unipd.it/en/msca-marathon23. La pagina contiene anche i nominativi dei docenti che negli scorsi anni si sono proposti quali Supervisor, decidendo di accogliere potenziali Fellow Marie Sklodowska-Curie nel proprio team di ricerca. Chi di voi avesse intenzione di ricoprire per la prima volta il ruolo di Supervisor, o di aggiornare i propri dati, può segnalarlo compilando il modulo on line: https://www.unipd.it/supervisor-form. Per maggiori dettagli sul bando MSCA-PF e sull’importanza dell’azione dei Supervisor nei progetti, vi invito a visionare la registrazione dell’incontro FOCUS ON MSCA – “Le Azioni MSCA Postdoctoral Fellowships in Horizon Europe: Perché fare il supervisor?” (accesso con Single Sign On):https://elearning.unipd.it/ufficiserviziapplicazioni/mod/page/view.php?id=1 5936 Vi chiedo di collaborare attivamente alla diffusione dell’iniziativa, così da favorire la più ampia partecipazione dell’Ateneo al prossimo bando MSCA-PF.

expression of interest for mini-symposium on Graphical Models for Life Science
by Daniela De Canditiis 03 Mar '23

03 Mar '23

Dear Colleagues, this is an invitation to express your interest in participating as a speaker at the following mini-symposium for the IMACS 2023 that will be in September in Rome *Site of Congress*: https://www.imacs2023.eu/index.php/IMACS2023/IMACS2023 *Title of the mini_symposium*: “Graphical Models for Life Science” *Organizers*: Claudia Angelini, Daniela De Canditiis and Italia De Feis (IAC-CNR) *Abstract*: Graphical models are an elegant framework for describing complex systems of random variables. The nodes represent variables, while the edges represent relationships among variables, such as conditional independence. Bayesian networks are direct acyclic graphs, while Markov networks are undirect graphs, both have undergone enormous development in the last decades. Graphical models are helpful for the statistical analysis of data in various domains. Recently, they are becoming strategic for life science, allowing us to infer relations among variables such as genes/proteins/diseases/. However, their use in life science opens novel challenges due to the amount and heterogeneity of the data. This Special Session is open to theoretical and methodological contributions and innovative applications in life science. All interested researchers are welcome to email one of the organizers by the 20th of March 2023.

Seminar by Alessandra Faggionato, on March 6th, Padova Seminars in Probability and Finance
by Alberto Chiarini 02 Mar '23

02 Mar '23

Dear Colleagues, We would like to invite you to the "Padova Seminars in Probability and Finance seminar" that will take place on March 6th, 2023 at 16.00, Room 1BC45 at the department of Mathematics “Tullio Levi-Civita". The seminar will be held in person and online via the Zoom platform. _____________________________________________________ Speaker: Alessandra Faggionato (Università La Sapienza) Title: Hydrodynamic limit of simple exclusion processes on point processes with random conductances Date and time: Monday, MARCH 6th at 16.00 Place: room 1BC45 at the Department of Mathematics, University of Padova Zoom link: https://unipd.zoom.us/j/83774362817?pwd=ZDZnRGdZZGpDNDRQd3pMQUw4NUx4dz09 available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: We consider continuous-time random walks on a simple point process with random symmetric jump rates. The jump range can be unbounded. We assume some second-moment conditions and that the above randomness is left invariant by the action of the group G = R^d or G = Z^d. We then add the site-exclusion interaction, thus making the particle system a simple exclusion process. We show that, for almost all environments, under diffusive space-time rescaling the system exhibits a hydrodynamic limit in path space. The hydrodynamic equation is non-random and governed by the effective homogenized matrix D of the single random walk, which can be degenerate. The proof relies both on particle duality and on stochastic homogenization for a single random walk. We then focus on specific examples, including the simple exclusion process on Delaunay triangulations.

Seminario di Markus Fischer - 7 marzo, Sapienza Università di Roma
by Giacomo Di Gesu 02 Mar '23

02 Mar '23

Martedì 7 marzo, ore 14:00, Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma. *Speaker: *Markus Fischer, Università di Padova *Title: *On correlated equilibria and mean field games *Abstract: *Mean field games are limit models for symmetric N-player games, as the number of players N tends to infinity. The prelimit models are usually solved in terms of Nash equilibria. A generalization of the notion of Nash equilibrium, due to Robert Aumann (1974, 1987), is that of correlated equilibrium. In a simple discrete setting, we will discuss correlated equilibria for mean field games and their connection with the underlying N-player games. We first consider equilibria in restricted strategies (Markov open-loop), where control actions depend only on time and a player's own state. In this case, N-player correlated equilibria are seen to converge to the mean field game limit and, conversely, correlated mean field game solutions induce approximate N-player correlated equilibria. We then discuss the problem of constructing approximate equilibria when deviating players have access to the aggregate system state. We also give an explicit example of a correlated mean field game solution not of Nash-type. Results (with L. Campi and Federico Cannerozzi) on a related notion of equilibrium in a diffusion-type setting will be mentioned as well.

Seminar Prof. Kostas Kardaras on "Portfolio choice under taxation and time constraints", 02/03/2023 at 4:30pm (fwd)
by Tiziano Vargiolu 01 Mar '23

01 Mar '23

****************************** WHEN? Thursday 2 March 2023 at 4:30pm WHERE? Room: 2BC60 - TORRE ARCHIMEDE, via Trieste 63, 35121 Padova (only in presence) WHO? Prof. Kostas Kardaras (LSE London) WHAT? Seminar on "Portfolio choice under taxation and time constraints" Abstract: We consider the problem of choosing an investment strategy that will maximise utility over distributions, under capital gains tax and constraints on the expected liquidation date. We show that the problem can be decomposed in two separate ones. The first involves choosing an optimal target distribution, while the second involves optimally realising this distribution via an investment strategy and stopping time. For the latter step, a variant of the Azema-Yor solution to the Skorokhod embedding problem is utilised, and its description is given very precisely in terms of solutions to algebraic equations.

Webinar PRISMA lunedì 6 marzo GUBINELLI-CALVIA
by Claudia Ceci 28 Feb '23

28 Feb '23

Buongiorno a tutt* ho il piacere di annunciare il prossimo webinar del ciclo di seminari online promosso dal Gruppo UMI PRISMA (http://www.umi-prisma.polito.it/index.html) *Lunedì 6 marzo 2023, * *ore 16-17 Alessandro Calvia* *Titolo: *Stochastic filtering in a non-Markovian framework with predictable jump times. *Abstract:* Stochastic filtering is a classic branch of applied probability. Research on this subject began with the pioneering works of N. Wiener and R. E. Kalman; since then, it has vastly expanded in numerous directions and is still ongoing. The starting point of a stochastic filtering problem is a partially observed system, i.e., a model consisting of a signal (or unobserved) process and an observed process. The main goal is to compute an equation satisfied by the filter, which is the conditional distribution of the hidden signal given the available observation. To deduce filtering equations, classic models usually feature Markovian signal-observation pairs that may only have totally inaccessible jump times. In this talk I will present a non-Markovian model, with path-dependent coefficients, that also allows for predictable jump times both in the signal and in the observed process. These two features naturally arise in various applications and require some new ideas and non-trivial technical tools to be dealt with in the context of stochastic filtering. After providing some examples, I will deduce the filtering equation and, if time permits, I will discuss some possible future research. This is joint work with Elena Bandini and Katia Colaneri. *ore 17-18 **Massimiliano Gubinelli* *Titolo:* What is stochastic quantisation? *Abstract:* Euclidean quantum fields (EQFs) are probability measures on spaces of generalized functions on R^d out of which one can construct quantum field theories via a well understood procedure. Proving the existence of non-Gaussian Euclidean quantum fields in dimensions d=2,3 has been proved quite challenging, and informed the development of new mathematical techniques (logarithmic Sobolev inequalities, phase-space expansion, cluster and polymer expansions, renormalization group). More recently, also thanks to development in the theory of singular stochastic partial differential equations, the study of these probability measures has been taken on again, from the point of view of stochastic analysis. I will try to give a broad panorama of this stochastic approach, of his results and of the many open problems. As a result I would like to motivate the idea that stochastic quantisation should be seen as a novel kind of stochastic analysis adapted to situations, like EQFs, where stochastic calculus alone is not effective due to singular nature of the objects or the lack of a useful filtration.

OWPS Tomorrow: Alan Hammond and Tyler J. Helmuth
by Alberto Chiarini 28 Feb '23

28 Feb '23

Dear all, A reminder that tomorrow (Wednesday), from 15:00 to 17:00 UTC, Alan Hammond and Tyler J. Helmuth will be speaking at the One World Probability Seminar. Titles, abstracts and the zoom link are below the signature and will also be posted on the website https://www.owprobability.org/one-world-probability-seminar. We kindly ask that you share this message within your community. Best wishes, Alberto Chiarini and Adrián González Casanova ----------------------------------------------------------------------------------------------------------- Talk 1 : Alan Hammond (Berkeley) Title : Stake-governed random-turn games Abstract : Many combinatorial games, such as chess, Go and Hex, are zero-sum games in which two players alternate in making moves. In a random turn variant, each player wins the right to move at any given turn according to the flip of a fair coin. In 2007, Peres, Schramm, Sheffield and Wilson [PSSW] found explicit optimal strategies for a broad class of random-turn games, including Hex (which remains unsolved in its alternating-turn form on the 11-by-11 boards in which it is often played in tournaments). In this talk, we discuss stake-governed random-turn games, introduced recently in joint work with Gábor Pete. Two players of Hex are each given a certain limited budget at the outset of the game. At each turn, each stakes some part of what remains of her budget. The ensuing turn is random, with a player winning the right to move according to the proportion that her stake composes of the total stake at the turn. How much should a player stake at any given turn? Opposing pressures compete: stake too little, and lose the turn; too much, and be left with too little for later in the game. So this question concerns how to evaluate the relative strategic importance of intermediate positions in multi-turn games. We answer it for a class of games that are cousins of the random tug-of-war games introduced by PSSW in 2009; these authors forged a connection between game theory and the infinity Laplacian (which is an L^\infty counterpart to the usual L^2 Laplacian), and we will see how, in a discrete context at least, this connection extends to stake-governed random-turn games. Talk 2 : Tyler J. Helmuth (Durham University) Title : The Arboreal Gas Abstract : In Bernoulli bond percolation each edge of a graph is declared open with probability p, and closed otherwise. Typically one asks questions about the geometry of the random subgraph of open edges. The arboreal gas is the probability measure obtained by conditioning on the event that the percolation subgraph is a forest, i.e., contains no cycles. Physically, this is a model for studying the gelation of branched polymers. What are the percolative properties of these random forests? Do they contain giant trees? I will discuss what is known and conjectured.

Seminar in Statistics - Giovanni Rabitti & Thomas Berrett
by Pierpaolo De Blasi 24 Feb '23

24 Feb '23

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 3 Marzo 2023, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terranno i seguenti 2 seminari: ------------------------------------------------ Time: 11.00 - 12.00 Speaker: *Giovanni Rabitti* (Heriot Watt University, Edinburgh) Title: *Fantastic sensitivity measures and where to find them* Abstract: Data science and scientific modeling are extensively used to provide predictions for policy-making purposes. However, resulting communications need to be supported by a proper uncertainty quantification to assess variability in model predictions, by the identification of the key-uncertainty drivers. This information can be provided by statisticians with sensitivity analysis methods. Knowing the drivers of uncertainty supports effective policy-making. This talk is a guided tour in sensitivity analysis techniques and some recent results. In the first part of the talk, starting from the basics, local and global methods will be introduced. When the model is large (i.e. with many input variables), screening techniques are typically used to reduce the dimensionality of the scientific model and will be presented in the talk. In the second part of the talk, I will introduce cooperative games techniques to assess variable importance. I will present recent results on the computation on these importance measures, as well as their application to GAM models, to extreme value problems and to two actuarial pricing models. If there is time, I will introduce a game-theoretic interaction index for discovering subjects at higher identification risk. ------------------------------------------------ Time: 12.00 - 13.00 Speaker: *Thomas Berrett* (University of Warwick) Title: *Optimal nonparametric testing of Missing Completely At Random, and its connections to compatibility* Abstract: Given a set of incomplete observations, we study the nonparametric problem of testing whether data are Missing Completely At Random (MCAR). Our first contribution is to characterise precisely the set of alternatives that can be distinguished from the MCAR null hypothesis. This reveals interesting and novel links to the theory of Frechet classes (in particular, compatible distributions) and linear programming, that allow us to propose MCAR tests that are consistent against all detectable alternatives. We define an incompatibility index as a natural measure of ease of detectability, establish its key properties, and show how it can be computed exactly in some cases and bounded in others. Moreover, we prove that our tests can attain the minimax separation rate according to this measure, up to logarithmic factors. Our methodology does not require any complete cases to be effective, and is available in the R package MCARtest. ------------------------------------------------ Sarà possibile seguire entrambi i seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88246009718?pwd=UnVxL2R5RThwQllDbWVnbTdRNGVMUT09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Seminar by Dr. Piero Mazzarisi.
by Giorgio Rizzini 24 Feb '23

24 Feb '23

Dear all, we are glad to announce the following seminar by Dr. Piero Mazzarisi (University of Siena) on Tuesday, February 28th 2023 starting from 11:00 in room 4026 at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca (Milan). *Realized Random Graphs, with an application to the Interbank Network* *Piero Mazzarisi* Department of Economics and Statistics University of Siena *Abstract:* This work introduces a new econometric methodology to infer dynamic network models driven by latent state variables. The main idea is to obtain a noisy representation of the state variables dynamics by computing a sequence of cross-sectional estimates of the network model at each point in time. The dynamic modeling of these cross-sectional estimates, that we name realized random graphs, transforms the original nonlinear state-space network model into a linear time-series model that can easily be estimated. Under the assumption that the network is dense, and of a mixed-membership blockmodel structure, we show that the model parameters and the unobservable state variables can be estimated at a super-consistent rate of convergence for large cross sections. By allowing for an extremely rich parameterization of the model in high dimensions, the proposed methodology describes the heterogeneous topology of real-world networks. We corroborate our findings by using this novel framework to estimate and forecast the dynamic common factors driving the evolution of the Italian electronic market of interbank deposits. *February 28th, 2023, 11:00 a.m.* *Department of Statistics and Quantitative Methods* Aula Seminari 4026 - Building U7 (Fourth floor*)* *Bicocca degli Arcimboldi street, 8 – 20126 Milan* For further information, please write to *rosanna.grassi(a)unimib.it <rosanna.grassi(a)unimib.it>*

SPASS Seminars: M. Aleandri and M. Rehmeier
by Francesco Grotto 21 Feb '23

21 Feb '23

Dear Colleagues, We would like to invite you to the following SPASS seminar by Marco Rehmeier (U. Bielefeld) and Michele Aleandri (Sapienza), jointly organized by UniPi, SNS, UniFi and UniSi. The seminars will take place on TUE, 28.2.2023 starting at 14:00 CET in Sala Seminari, Dipartimento di Matematica, Pisa. The seminars will also be broadcasted on Google Meet, follow the link below for the streaming. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass Marco Rehmeier (Bielefeld University), 14:00 Title: On nonlinear Markov Processes in the sense of McKean Abstract: We study nonlinear Markov processes in the sense of McKean and present a large new class of examples. Our notion of nonlinear Markov property is in McKean's spirit, but more general in order to include examples of such processes whose one-dimensional time marginals solve a nonlinear parabolic PDE, such as Burgers' equation, the porous media equation, or variants of the latter with transport-type drift. We show that the associated nonlinear Markov process is given by path laws of weak solutions to a corresponding distribution-dependent stochastic differential equation whose coefficients depend singularly (i.e. Nemytskii-type) on its one-dimensional time marginals. Moreover, we show that also for general nonlinear Markov processes, their path laws are uniquely determined by one-dimensional time marginals of suitable associated conditional path laws. Furthermore, we characterize the extremality of the curves of the one-dimensional time marginals of our nonlinear Markov Processes in the class of all solutions to the associated linearized PDE and, this way, obtain new interesting results also for the classical linear case. This is joint work with Michael Röckner. Michele Aleandri (Università di Roma La Sapienza), 15:00 Title: Opinion dynamics with Lotka-Volterra type interactions Abstract: We investigate a class of models for opinion dynamics in a population with two interacting families of individuals. Each family has an intrinsic mean field “Voter-like” dynamics which is influenced by interaction with the other family. The interaction terms describe a cooperative/conformist or competitive/nonconformist attitude of one family with respect to the other. We prove chaos propagation, i.e., we show that on any time interval [0; T], as the size of the system goes to infinity, each individual behaves independently of the others with transition rates driven by a macroscopic equation. We focus in particular on models with Lotka-Volterra type interactions, i.e., models with cooperative vs. competitive families. For these models, although the microscopic system is driven a.s. to consensus within each family, a periodic behaviour arises in the macroscopic scale. In order to describe fluctuations between the limiting periodic orbits, we identify a slow variable in the microscopic system and, through an averaging principle, we find a diffusion which describes the macroscopic dynamics of such variable on a larger time scale.

Mi presento
by Marco Zamparo 20 Feb '23

20 Feb '23

Buongiorno a tutti, da qualche ora sono parte di questa vostra lista. Questo breve messaggio è per presentarmi a quelli di voi che ancora non mi conoscono. Mi chiamo Marco Zamparo e sono un fisico teorico "pentito" che da qualche anno si occupa di probabilità e fisica statistica rigorosa. Allego un CV aggiornato per i curiosi. Sto lavorando al modello di pinning dei polimeri con Giambattista Giacomin (Université Paris Cité) e ai processi di rinnovo in ambiente random con Frank den Hollander (Universiteit Leiden). Sono inoltre interessato allo studio del gas di Lévy-Lorentz, del quale ho parzialmente caratterizzato le proprietà di trasporto. Ho un RTDA in fisica teorica e sono in cerca di una posizione in probabilità o fisica matematica per poter completare la "trasformazione". Dati i vincoli Gelmini sugli anni di precariato, sono costretto a considerare solo RTDB o nuovi RTT. Sono in possesso dell'abilitazione scientifica nazionale in fisica matematica (MAT/07) e a maggio chiederò quella in probabilità (MAT/06). Se qualcuno avesse piacere di conoscermi, sarei lieto di fare una presentazione o un seminario. Non vi rubo altro tempo. Grazie per l'attenzione! Buona settimana, Marco

Dear all, We are delighted to announce the 2nd BioInference conference (https://bioinference.github.io/2023<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbioinfer…>), taking place at the Doctoral Training Centre at the University of Oxford on the 8th-9th June 2023. Launched in 2022, BioInference aims to bring together researchers from across statistics and mathematical modelling who work with biological systems, and from all career stages, to foster discussions between the two communities and to prompt collaborations. The talks from the 1st BioInference conference are available via our public YouTube channel (shorturl.at/ekmqT<https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fshorturl.…>). The conference will combine contributed talks and poster sessions. We invite abstracts for oral / poster presentations on work either relating to statistical methods development (so long as those methods are applicable to biological systems) or on the application of statistical methods to solve biological problems. We are especially interested in presentations on biological problems where an inference solution has yet to be found (i.e. unsolved inference problems). Abstracts can be submitted via a Google form (shorturl.at/dfo68<https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fshorturl.…>) and the deadline is midday on the 16th March 2023. The conference organising committee is committed to ensuring fair participation of individuals across all career stages, genders, races and ethnicities, ages, geographic locations, and universities. Kind regards, The BioInference Organisers Ioana Bouros (Oxford); Fergus Cooper (Oxford); Richard Creswell (Oxford); Aden Forrow (Maine); Ben Lambert (Exeter); Chon Lok Lei (Macau); Massimiliano Tamborrino (Warwick); Tom Thorne (Surrey) ------ Dr. Massimiliano Tamborrino Associate Professor Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwarwick.…>

PostDoc position on Physics-Informed Machine Learning at IDSIA USI-SUPSI
by Azzimonti Laura 15 Feb '23

15 Feb '23

The "Dalle Molle" Institute for Artificial Intelligence (IDSIA) in Lugano, Switzerland is looking for a PosDoc Researcher in physics-informed machine learning. The position is framed within the EU-funded project PRAESIIDIUM, in collaboration with an outstanding team of academic, medical and industrial partners from all over Europe. We will develop a prototype tool for real-time prediction of the pre-diabetic risk based on the integration of patient-specific mathematical models and a rich dataset of real-life data. The approach will rely on novel physics-informed machine learning (ML) techniques in order to overcome the limits of standard “black-box” ML practice, while reducing the computational time for simulating heavy numerical models and improving their prediction performances. *** About the position *** We look for candidates with a Ph.D. in mathematics, physics, engineering, computer science, or related areas. The ideal candidate should have a solid background in mathematical modelling, ordinary and partial differential equations, dynamical systems, machine learning and/or related fields, good programming skills in R and/or Python and a strong commitment to fulfill research objectives. We offer a fixed-term position (initially for two years, with intent of prolongation) with an attractive salary, in line with Swiss standards and the candidate’s experience. *** About the application *** The instructions for the application, and other details of the call, can be found at the following link: https://www.supsi.ch/home_en/supsi/lavora-con-noi/2023-04-02-bando1850 Deadline: 2nd April 2023 *** About IDSIA *** IDSIA is a world-class research institute on AI founded in 1988, affiliated with both Università della Svizzera Italiana (USI) and Scuola Universitaria Professionale della Svizzera Italiana (SUPSI). It counts more than 100 staff researchers and more than 40 Ph.D. students, active in the research areas of machine learning, optimisation and control, autonomous robotics, intelligent networked systems, geometric computing and vision, natural language processing and information retrieval. IDSIA is based in the beautiful city of Lugano (Canton Ticino, Switzerland), located at the new USI-SUPSI Campus Est of Viganello-Lugano, a few hundred meters from the city center and the lake of Lugano. ––––––––––––––––––––––––––––––– http://people.idsia.ch/~laura.azzimonti/

OWPS Tomorrow: Frank den Hollander and Elena Pulvirenti
by Alberto Chiarini 14 Feb '23

14 Feb '23

Dear all, A reminder that tomorrow (Wednesday), from 15:00 to 17:00 UTC, Frank den Hollander and Elena Pulvirenti will be speaking at the One World Probability Seminar. Titles, abstracts and the zoom link are below the signature and will also be posted on the website https://www.owprobability.org/one-world-probability-seminar. We kindly ask for your help to share this message within your community. Best wishes, Alberto Chiarini and Adrián González Casanova ---------------------- Speakers: Frank den Hollander (Leiden) and Elena Pulvirenti (Delft) Talk 1 : Metastability for the Widom-Rowlinson model: I. Planar discs. Abstract We define the static Widom-Rowlinson model on a two-dimensional finite torus. The energy of a particle configuration is determined by its halo, defined as the union of unit discs centred at the positions of the particles. We discuss the metastable behaviour of a dynamic version of the model, in which particles are randomly created and annihilated as if the outside of the torus were an infinite reservoir with a given chemical potential. We start with the empty torus and are interested in the first time when the torus is fully covered by unit discs. This can be viewed as the crossover time from a ‘gas phase’ to a ‘liquid phase’. We consider the metastable regime where the temperature is low and the chemical potential is supercritical. In order to achieve the transition from empty to full, the system needs to create a sufficiently large droplet, called critical droplet, which triggers the crossover. It turns out that the critical droplet is close to a disc of a certain deterministic radius, with a boundary that is random and consists of a large number of unit discs that stick out by a small distance. We show how an analysis of the surface fluctuations allows us to derive both a volume term and a surface term in the asymptotics of the average crossover time. Based on joint work with Sabine Jansen (Munich) and Roman Kotecký (Prague). Talk 2 : Metastability for the Widom-Rowlinson model: II. Grains of general shape. Abstract We investigate what happens when the planar discs are replaced by convex grains in arbitrary dimensions whose shape may be random. We identify the size and the shape of the critical droplet as a function of the shape distribution for the grains. We also identify the volume term in the asymptotics of the average crossover time. In addition, we speculate about the surface term, formulating a conjecture about what it should look like. There are various interesting subcases, showing that the shape of the grains has a rather delicate influence on the critical droplet and the average crossover time. Based on joint work with Yogesh Dhandapani (Bangalore) and Roman Kotecký (Prague).
