Seminari di Fisica Matematica Dipartimento di Matematica "G. Castelnuovo" Università di Roma La Sapienza Mercoledì 5 aprile, ore 16:15, sala di Consiglio Fraydoun Rezakhanlou (University of Berkeley) Kinetic Theory for Laguerre Tessellations Abstract. In this talk I will discuss a family of Gibbsian measures on the set of Laguerre tessellations. These measures may be used to provide a systematic approach for constructing Gibbsian solutions to Hamilton-Jacobi PDEs by exploring the Eularian description of the shock dynamics. Such solutions depend on kernels satisfying kinetic-like equations reminiscent of the Smoluchowski model for coagulating and fragmenting particles. Tutti gli interessati sono invitati a partecipare.

Webinar UMI-PRISMA 3 aprile Campi-Callegaro
by Claudia Ceci 27 Mar '23

27 Mar '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 3 aprile 2023* ore 16-17 LUCIANO CAMPI Title: Correlated equilibria and mean field games Abstract: In the context of mean field games (MFGs), we introduce a generalization of mean field game solution, called correlated solution, which can be seen as the mean field game analogue of a correlated equilibrium. The latter is a generalization of Nash equilibrium for stochastic games. Our notion of solution can be justified in two ways for MFGs in discrete time and finite state space: correlated solutions arise as limits of exchangeable correlated equilibria in restricted (Markov open-loop) strategies for the underlying $N$-player games, and approximate $N$-player correlated equilibria can be constructed starting from a correlated solution to the mean field game. Moreover, those results can be extended to progressive deviations, possibly depending on the whole history of the state and the flow of measures. In this talk we will focus especially on a further extension to continuous time MFGs through the notion of coarse correlated equilibrium. This talk is based on joint works with O. Bonesini, F. Cannerozzi and M. Fischer. ore 17-18 GIORGIA CALLEGARO Title: McKean–Vlasov Game of Commodity Production, Consumption and Trading Abstract: We propose a model where a producer and a consumer can affect the price dynamics of some commodity controlling drift and volatility of, respectively, the production rate and the consumption rate. We assume that the producer has a short position in a forward contract on λ units of the underlying at a fixed price F, while the consumer has the corresponding long position. Moreover, both players are risk-averse with respect to their financial position and their risk aversions are modelled through an integrated-variance penalization. We study the impact of risk aversion on the interaction between the producer and the consumer as well as on the derivative price. In mathematical terms, we are dealing with a two-player linear-quadratic McKean–Vlasov stochastic differential game. Using methods based on the martingale optimality principle and BSDEs, we find a Nash equilibrium and characterize the corresponding strategies and payoffs in semi-explicit form. Furthermore, we compute the two indifference prices (one for the producer and one for the consumer) induced by that equilibrium and we determine the quantity λ such that the players agree on the price. Finally, we illustrate our results with some numerics. In particular, we focus on how the risk aversions and the volatility control costs of the players affect the derivative price.

Dear Colleagues, it is my pleasure to invite you to the following seminar in Quantitative Finance, organised by LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto (CCA), that will take place at CCA in Torino and can be followed via zoom. At the event page link you can find the paper, the zoom link to attend online and a button to add the event to your calendars. ------------------------------------------------------------------------------------------- March 22nd @ 12.00 Speaker: Peter Tankov (ENSAE) Title: Decarbonization of financial markets: a mean-field game approach Abstract:We build a model of a financial market where a large number offirms determine their dynamic emission strategies under climate transition risk in the presence of both green-minded and neutral investors.The firms aim to achieve a trade-off between financial and environ-mental performance, while interacting through the stochastic discountfactor, determined in equilibrium by the investors’ allocations. We formalize the problem in the setting of mean-field games and prove the existence and uniqueness of a Nash equilibrium for firms. We then presenta convergent numerical algorithm for computing this equilibrium andillustrate the impact of climate transition risk and the presence ofgreen-minded investors on the market decarbonization dynamics andshare prices. We show that uncertainty about future climate risks andpolicies leads to higher overall emissions and higher spreads betweenshare prices of green and brown companies. This effect is partially reversed in the presence of environmentally concerned investors, whoseimpact on the cost of capital spurs companies to reduce emissions.

Seminar by Dr. Vincenzo Candila.
by Giorgio Rizzini 24 Mar '23

24 Mar '23

Dear all, we are glad to announce the following seminar by Dr. *Vincenzo Candila* (University of Salerno) on Wednesday March 29th 2023 starting from 4:30 p.m. in room 2062 at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca (Milan). *On the tennis winner forecasting methods: from the Weighted Elo rates to the network-based indicators* *Vincenzo **Candila* Department of Economics and Statistics University of Salerno *Abstract:* Statistical methods for predicting the winner in tennis matches have increased in popularity over the last two decades. Currently, several techniques are available, such as the regression-based, point-based, and paired-comparison approaches. Within this latter class, the Elo rating is one of the most popular methods to predict the probability of winning tennis matches. Even with its widely recognized merits in terms of good performance, the Elo method only partially considers each player's current form and recent performances. To overcome this drawback, we have proposed a new version of the Elo rating method, labeled Weighted Elo (WElo), where the standard Elo rates are weighted according to the scoreline of the players’ last match. More recently, we have further enlarged the paired-comparison class of models, introducing the network-based indicators for the first time to allow the ratings of the whole set of players to vary every time there is a new match. This work aims to illustrate the main characteristics of the WElo and network-based rates. In the empirical applications, we show the statistically meaningful benefits of using the proposed approaches with respect to many popular competing specifications. *March 29th, 2023 at 4:30 p.m.* *Department of Statistics and Quantitative Methods* *Room **2062* * - Building U7 (Second floor)* *Bicocca degli Arcimboldi street, 8 – 20126 Milan* For further information, please write to rosanna.grassi(a)unimib.it

Seminar: Francesco Vaccarino at Tor Vergata
by salvi 23 Mar '23

23 Mar '23

Dear all, On Wednesday, February 15th, at 14h00 in Aula Dal Passo at Roma Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Francesco Vaccarino (Politecnico di Torino) with the seminar _ _ _"Hodge-Shapley game: a Laplacian-based Shapley-like associated game for eXplainable AI"_ _ _ Abstract: In cooperative game theory, a set of players or decision-makers should negotiate to decide how to allocate the worth gained by the coalition composed of all the players. A value is a solution concept that suggests the outcome of the negotiation among players. Among the many existing alternative solution concepts, it is prevalent the Shapley value solution concept. Its popularity also derives from the property of being a fair allocation, where a set of desirable properties or axioms describes fairness. The axioms characterize the Shapley value in the sense that it is the unique value satisfying those properties; at the same time, the axioms allow deriving a simple explicit combinatorial formula to compute the Shapley value. In our approach, coalitions are the main subjects of cooperation, instead of single players, and, inspired by the Shapley value, the goal is to derive a fair associated game, i.e. an allocation to coalitions satisfying a set of desirable properties. The methodology is based on using the Hodge decomposition of the simplicial complex associated with the partially ordered set of the subsets of the set of players ordered by inclusion. We will motivate this investigation within the framework of Explainable Artificial Intelligence (XAI). Joint work with Antonio Mastropietro (Eurecom - F) We encourage in-person partecipation. Should you be unable to come, here is the link to the event on Teams: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… The seminar is part of the Excellence Project Math@TOV.

With best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ----------------------------------------------------------------------------------------------------------- Talk : Milton Jara (IMPA) and Otávio Menezes (Purdue University) Title : CLT for NESS Abstract : Non-equilibrium stationary states (NESS) are ubiquitous in nature, but not well understood from a mathematical point of view. The main features of NESS is the presence of non-trivial currents, which generate long-range correlations in the system. Modeling physical systems by Markov chains, one can restate questions about NESS as the description of invariant measures for non-reversible Markov chains. This opens the way to describe NESS by probabilistic methods. However, basic questions for non-reversible Markov chains, like for example mixing times or quantitative CLTs are not been answered in great generality. Our first talk will introduce NESS with some examples, and it will introduce general and fairly elementary methodology for Markov chains that we believe is well suited to the study of non-reversible Markov chains. The second talk will describe some recent results about the description of NESS for driven-diffusive systems.

Seminar announcement: M. Tarsia on time-inconsistent recursive stochastic control problems – March 29, 2023 – 13:00-14:00
by Mastrogiacomo Elisa 21 Mar '23

21 Mar '23

Dear Colleagues, On March 29, 2023, 13:00-14:00, Dr. Marco Tarsia (University of Insubria) will give a talk on “Subgame-perfect equilibrium strategies for time-inconsistent recursive stochastic control problems” (joint work with Elisa Mastrogiacomo). The seminar will be held in person and online via the MS Teams platform. Link: https://teams.microsoft.com/l/meetup-join/19%3ameeting_OWU0MDRiNjctYWNmYS00… Place: Dipartimento di Economia, Via Monte Generoso 71, room TBA. Below you can find an abstract of Marco’s talk. You are all invited. *** Abstract In this talk, we discuss about time-inconsistent recursive stochastic control problems, i.e., for which Bellman’s principle of optimality does not hold. In practice, a restriction of an optimal control for a specific initial pair on a later time interval might not be optimal for that corresponding initial pair; this happens, for instance, in dynamic utility maximization problems for investment- consumption strategies under non-exponential discounting. For this class of problems classical optimal controls may fail to exist, or to be relevant in practice, and dynamic programming is not easily applicable. Therefore, the notion of optimality is defined through a game-theoretic framework by means of subgame-perfect equilibrium: we interpret our preference changes which, realistically, are inconsistent over time, as players in a game for which we want to find a Nash equilibrium. The approach followed in our work relies on the stochastic (Pontryagin) maximum principle: we adapt the classical spike variation technique to obtain a characterization of equilibrium strategies in terms of a generalized second-order Hamiltonian function defined through pairs of backward stochastic differential equations, even in the multidimensional case. We emphasize that, similarly to the classical case, equilibrium strategies are characterized through both a necessary condition and a sufficient condition involving the generalized Hamiltonian function, whereas, contrary to the classical case, this sufficient condition works even in the absence of extra convexity assumptions. Going further, our analysis is extended to time-inconsistent recursive stochastic control problems under a constraint defined by means of an additional recursive utility, under appropriate boundedness assumptions. That constraint refers to an expected value and so we adapt Ekeland’s variational principle to this trickier situation. Finally, the theoretical results are applied in the financial field to finite horizon investment-consumption policies with non-exponential actualization. Here the existence of non-trivial equilibrium policies is also ascertained.

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.

Padova Seminars in Probability and Finance - Nicola Turchi (Università Milano Bicocca)
by alessandra bianchi 20 Mar '23

20 Mar '23

Dear Colleagues, We would like to invite you to the following seminar that will take place on March 31 at 14.30 at the Math Department of Padova. The seminar will be held in person and online via the Zoom platform. The organizers, Alessandra Bianchi, Giorgia Callegaro, Marco Formentin _____________________________________________________ *Speaker*: Nicola Turchi (Università Milano Bicocca) *Title*: High-dimensional random polytopes of the Beta kind *Date and time*: Friday, MARCH 31 at 14.30 *Place*: room 1BC45 at the Department of Mathematics, University of Padova *Zoom link*: https://unipd.zoom.us/j/82935460505 (Meeting ID 829 3546 0505) available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ *Abstract*: Beta polytopes are a class of random polytopes, which arise as convex hulls of independent random points distributed according to a certain radially-symmetric probability distribution supported on the Euclidean ball, called the beta distribution. A prominent reason for the interest surrounding them is that the beta distribution exhibits peculiar properties that make exact computations possible to achieve, contrarily to most other models of randomness with non-independent coordinates. As the space dimension grows, the expected fraction of the volume that these polytopes fill within their supporting balls can be asymptotically negligible or not, depending on the number of points which are picked in each dimension. In this talk we give an overview on how to quantify this statement, first showing a rough threshold for the aforementioned growth and secondly a more precise one, namely how many points are needed to get any fraction in average. Lastly, we show how we can handle more precise asymptotics for the approach towards zero in the lower regimes of points, based on a work in progress with G. Bonnet and Z. Kabluchko. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

LTI@Unito Seminars| Dimitri Vayanos (March 7) and Johan Hombert (March 8) @ 12.00
by Luca Regis 17 Mar '23

17 Mar '23

Dear Colleagues, it is my pleasure to invite you to the following two seminars in Quantitative Finance, organised by LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto (CCA): ------------------------------------------------------------------------------------------- March 7th @ 12.00 (webinar) Speaker: Dimitri Vayanos (LSE) Title: Passive Investing and the Rise of Mega-Firms Abstract: We study how passive investing affects asset prices. Flows into passive funds raise dispropor-tionately the stock prices of the economy’s largest firms—even when the indices tracked by the funds include all firms. Passive flows also raise the largest firms’ return volatility the most, andraise the aggregate stock market even when they are entirely due to investors switching from active to passive. These effects arise because of the re-pricing of systematic and large firms’idiosyncratic risk. We estimate that passive investing caused the 50 largest US firms to rise 30%more than the US stock market over 1996–2020.

Using the late 1990s Information and Communication Technology (ICT) boom as a laboratory, we show that skilled labor joining this new sector experienced sizeable long-term earnings losses. We trace these losses to skill obsolescence, that cannot be explained by either selection or the subsequent ICT sector bust. During the boom, capital flowed more to firms whose workers would ultimately experience a larger productivity decline. This suggests that financial capital can amplify the negative effects of labor reallocation into booming sectors on aggregate labor productivity.

40th Linz Seminar on Fuzzy Set Theory: Copulas – Theory and Applications
by Fabrizio, Antonio DURANTE 17 Mar '23

17 Mar '23

Dear Colleague, it is our pleasure to invite you to participate in the 40th Linz Seminar on Fuzzy Set Theory <https://www.flll.jku.at/linz2023> Copulas – Theory and Applications Bildungshaus St. Magdalena, Linz, Austria June 6-9, 2023 Since their inception in 1979 the Linz Seminars on Fuzzy Sets have emphasized the development of mathematical aspects in the context of fuzzy sets by bringing together researchers in fuzzy sets and established mathematicians whose work outside the fuzzy setting can provide direction for further research. The philosophy of the seminar has always been to keep it deliberately small and intimate so that informal critical discussions remain central. LINZ 2023 will be the 40th seminar carrying on this tradition and is devoted to the theme "Copulas — Theory and Applications". The goal of the seminar is to present and to discuss recent advances of copulas and related functions and their applications in pure and applied fields. Accordingly, the topics of the Seminar will include but not be limited to: · Copula theory o From bivariate to multivariate copulas o Dependence measures and association o Approximation and convergence of copulas o Measure theoretic aspects of copulas o Copulas in the discrete setting · Copula applications o Applications in pure and applied fields o Estimation in the context of copulas o Copula methods in Data Science o Feature selection · Relationship to other aggregation functions o Triangular (co)norms, implications o Uninorms, nullnorms o Quasi-copulas, semicopulas o Distribution functions The "Linz" tradition has these key features: the number of participants of the Linz Seminars is usually bounded above by 40 with broad international representation and an enjoyable mix of pure and applied interests; there are no parallel sessions so that all participants focus on each presentation and fully engage in each topic; and there is time for discussion of each presentation, with follow up round table(s) for discussion of open problems and issues raised in the talks. In particular, young researchers (PhD students, junior post-docs) are encouraged to submit their latest results. Please submit your extended abstract (up to 4 pages) by March 29th, 2023 following the guidelines provided at the webpage of the seminar. Further Information about the seminar(s) is available at: https://www.flll.jku.at/linz2023 and https://www.flll.jku.at/linzseminars We look forward to your contributions and to welcoming you in Linz, Best regards, Fabrizio Durante, Susanne Saminger-Platz, Wolfgang Trutschnig (Program Chairs) --------------------------------------------------------- Fabrizio Durante Dipartimento di Scienze dell'Economia Centro Ecotekne Pal.

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.

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.

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.*

The firms maximize a criterion depending on their financial performance (determined by the equilibrium share price), and their environmental performance. The interaction between the firms takes place through the stochastic discount factor, determined in equilibrium by the investors' preferences. We formalize the problem in the setting of mean-field games and prove the existence and uniqueness of a Nash equilibrium for firms. We then present a convergent numerical algorithm for computing this equilibrium and illustrate the impact of climate transition risk and the presence of green-minded investors on the market decarbonization dynamics and share prices in a variety of settings.

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.

De Finetti Risk Seminar - March 8, 2023
by Emanuela Rosazza Gianin 03 Mar '23

03 Mar '23

On behalf of the Scientific Committee of the "B. de Finetti Risk Seminars, Milano Lectures on the Mathematical Theory of Economics and Finance”, we are glad to invite you to participate at the following Lecture: Peter Tankov ENSAE Paris, France Title: Decarbonization dynamics of a large financial market: a mean-field game approach Abstract: We build a model of a financial market where a large number of firms determine their emission strategies under climate transition risk in the presence of both green-minded and neutral investors. The firms maximize a criterion depending on their financial performance (determined by the equilibrium share price), and their environmental performance. The interaction between the firms takes place through the stochastic discount factor, determined in equilibrium by the investors' preferences. We formalize the problem in the setting of mean-field games and prove the existence and uniqueness of a Nash equilibrium for firms. We then present a convergent numerical algorithm for computing this equilibrium and illustrate the impact of climate transition risk and the presence of green-minded investors on the market decarbonization dynamics and share prices in a variety of settings.

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. Best Regards Claudia Angelini: claudia.angelini(a)cnr.it <c.angelini(a)na.iac.cnr.it>, Daniela De Canditiis: d.decanditiis(a)iac.cnr.it, Italia De Feis: i.defeis(a)iac.cnr.it -- Daniela De Canditiis, PhD Istituto per le Applicazioni del Calcolo "M.Picone" (CNR) via dei Taurini, 19 -- 00185 Roma, Italy tel: +39 06 49937342 fax: +39 06 4404306 https://www.iac.cnr.it/personale/daniela-de-canditiis

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. Joint work with Ofelia Bonesini (Imperial College London) and Luciano Campi (University of Milan "La Statale")

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.

Next OWPS on March 1st: Alan Hammond and Tyler J. Helmuth
by Alberto Chiarini 20 Feb '23

20 Feb '23

OWPS's next session will be on Wednesday the 1s of March of from 15:00 to 17:00 UTC. Our next speakers are: Alan Hammond (Berkeley) and Tyler J. Helmuth (Durham University) 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 have found that many that subscribed to the mailing list to receive these updates are not receiving them anymore. If you are interested in the project, we kindly ask you to resubscribe to the mailing list and share this announcement within your community. With best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ----------------------------------------------------------------------------------------------------------- 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.

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, 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).

Buongiorno, si trasmette il link per seguire il seminario di Luisa Andreis (Politecnico di Milano) tramite Zoom: https://uniroma1.zoom.us/j/84073069369 Martedì 14 Febbraio, ore 14:00 Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Title: *Rare events in sparse random graphs *Abstract:* Rare events for dense random graphs are well described using the theory of large deviations and graphons. When graphs are sparse the picture is less clear, objects that describe globally the graphs and their limits, as graphons do for dense graphs, have not been defined yet. Nevertheless we do have information on how these graphs look like when explored locally from a vertex and this, under some assumptions, gives also information on global properties. In this talk we will give an overview on what is known on rare events in this regime, focusing in particular on large deviation statements on connected components in inhomogeneous random graphs and on links with coagulation processes. This talk is based on joint works with Wolfgang König (WIAS and TU Berlin), Tejas Iyer, Heide Langhammer, Elena Magnanini and Robert Patterson (WIAS).

Dear all, we are glad to inform you that it is now possible to pay the registration fee (by bank transfer or credit card) for the Applied Bayesian Statistics ABS23 which will be held in Firenze (Italy) on June, 12-16, 2023. Website: http://www.mi.imati.cnr.it/conferences/abs23/ The school is organised by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the Italian National Research Council in Milano), this year in cooperation with the Florence Center for Data Science and the Department of Statistics, Computer Science and Applications at the University of Firenze. The topic will be BAYESIAN CAUSAL INFERENCE. The lecturer will be FAN LI (Duke University, https://scholars.duke.edu/person/fli) with the support by researchers at the University of Firenze. The University of Firenze can issue a certificate stating that the course is worth 3 ECTS credits. Interested students can write to abs23(a)mi.imati.cnr.it Once you register on the school website: http://www.mi.imati.cnr.it/conferences/abs23/ you will receive an email with the link to pay by credit card as well as the information on payment by bank transfer (please note that the early registration fee is available until April, 15th, 2023). Please note that only a very limited number of seats is still available and that Firenze is a very popular tourist place, so that it is better to make arrangements as soon as possible. More details about accommodation are available in the ABS23 website. As in the past (since 2004), there will be a combination of theoretical and practical sessions, along with presentations by participants about their work (past, current and future) related to the topic of the school. OUTLINE: The aim of this course is to introduce the fundamental concepts and the state-of-the-art methods for causal inference under the potential outcomes framework, with an emphasis on the Bayesian inferential paradigm. Topics will cover randomized experiments, common methods for observational studies, such as propensity score, matching, weighting and doubly-robust estimation, heterogeneous treatment effects, sensitivity analysis, instrumental variables, principal stratification, panel data methods, and longitudinal treatments. Recent advances related to high dimensional analysis and machine learning will be naturally incorporated into the discussion. All methods will be illustrated via real world case studies. We hope you will be interested in the school and we would like to meet you in Firenze next year. We invite you also to share the information with people potentially interested.

SPASS Seminar: Lihan Wang
by Francesco Grotto 08 Feb '23

08 Feb '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: Accelerate Sampling Using Birth-Death Dynamics Lihan Wang (Carnigie-Mellon University, Max Planck Institute Leipzig) The seminar will take place on TUE, 14.2.2023 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: *In this talk, I will discuss the birth-death dynamics for sampling multimodal probability distributions, which is the spherical Hellinger gradient flow of relative entropy. The advantage of the birth-death dynamics is that, unlike any local dynamics such as Langevin dynamics, it allows global movement of mass directly from one mode to another, without the difficulty of going through low probability regions. We prove that the birth death dynamics converges to the unique invariant measure with a uniform rate under some mild conditions, showing its potential of overcoming metastability. We will also show that on torus, the kernelized dynamics, which is used for numerical simulation, Gamma-converges to the idealized dynamics as the kernel bandwidth shrinks to zero. Joint work with Yulong Lu (UMass Amherst) and Dejan Slepcev (CMU).

AVVISO di SEMINARIO Prof. Nikolai Leonenko School of Mathematics, Cardiff University, UK TITOLO Multiscaling, Intermittency and large deviation in limit theorems for superpositions of Ornstein-Uhlenbeck type processes Abstract Superpositions of Ornstein-Uhlenbeck type (supOU) processes provide a rich class of stationary stochastic processes for which the marginal distribution and the dependence structure may be modeled independently [1,2]. We investigate the limiting behavior of integrated supOU processes with finite variance[3,4,6] (see also [7] for multifaced behaviour of supOU processes in the case the infinite variance). We show that after suitable normalization four different limiting processes may arise. The type of limit depends on the decay of the correlation function as well as on the characteristic triplet of the marginal distribution. supOU processes, moreover, may exhibit intermittency, a phenomenon affecting the rate of growth of moments[3,4,5,6,8]. The intermittency phenomenon appears also in some other models, for example, in the subclass of ambit processes[2] known as trawl processes [5]. Joint work with D.

Best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ----------------------------------------------------------------------------------------------------------- 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).

Annuncio Seminario Sapienza - 9 Febbraio ore 16:00
by Lorenzo Taggi 05 Feb '23

05 Feb '23

Dipartimento di Matematica, Sapienza Università di Roma, Sala di Consiglio Giovedì 9 Febbraio 2023, ore 16:00 *Speaker:* Daniel Ueltschi, University of Warwick *Title*: Quantum spin chains, loop representations, dimerisation *Abstract:* In contrast to their classical counterparts, one-dimensional quantum spin systems are interesting, they have intriguing behaviour, and they are difficult to study. I will describe a family of systems with nearest-neighbour interactions and O(n) symmetry. Its ground state phase diagram is expected to have a rich structure. For large spins it is possible to prove the occurrence of dimerisation in an open domain. The proof involves a loop representation and the method of cluster expansions. This is joint work with Jakob Bjornberg, Peter Muhlbacher, and Bruno Nachtergaele.

Seminar: Giovanni Conforti at Tor Vergata
by mic sal 02 Feb '23

02 Feb '23

Dear all, On Wednesday, February 1st, at 14h00 in Aula Dal Passo at Roma Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Giovanni Conforti (École Polytechnique) with the seminar "A probabilistic approach to exponential convergence of Sinkhorn's algorithm" Abstract: The entropic optimal transport problem (EOT) is obtained adding an entropic regularisation term in the cost function of the Monge-Kantorovich problem and is nowadays regularly employed in machine learning applications as a more tractable and numerically more stable version of the optimal transport problem. On the other hand, E.Schrödinger asked back in 1931 the question of finding the most likely evolution of a cloud of independent Brownian particles conditionally to observations. The mathematical formulation of his question through large deviations theory is known as the Schrödinger problem and turns out to be fully equivalent to EOT. In this talk, I shall illustrate both viewpoints and then move on to sketch the ideas of a probabilistic method to show exponential convergence of Sinkhorn's algorithm, whose application the heart of the recent successful applications of EOT in statistical machine learning and beyond. In particular, we shall discuss how the proposed method opens new perspective for showing exponential convergence for marginal distribution that are non compactly supported. We encourage in-person partecipation.

SPASS Seminar: Elia Bisi and Michele Coghi
by Gianmarco Bet 01 Feb '23

01 Feb '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): Matrix Whittaker processes Elia Bisi (TU Wien) and Rough McKean-Vlasov dynamics for robust ensemble Kalman filtering Michele Coghi (Università di Trento) The seminars will take place on TUE, 7.2.2023 respectively at 14:00 CET and 15:00 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 <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- Matrix Whittaker processes Abstract: Our journey starts from interacting random walks with push-and-block dynamics. We then consider their positive temperature analogues, touching upon polymer partition functions. Finally, we arrive at matrix Whittaker processes, which are integrable models of interacting Markov dynamics on matrix spaces. Our main tools are intertwining relations and the theory of Markov functions, which we will review. This talk is based on a joint work with Jonas Arista and Neil O’Connell: https://arxiv.org/abs/2203.14868. Rough McKean-Vlasov dynamics for robust ensemble Kalman filtering Abstract: Motivated by the challenge of incorporating data into misspecified and multiscale dynamical models, we study a McKean-Vlasov equation that contains the data stream as a common driving rough path. This setting allows us to prove well-posedness as well as continuity with respect to the driver in an appropriate rough-path topology. The latter property is key in our subsequent development of a robust data assimilation methodology: We establish propagation of chaos for the associated interacting particle system, which in turn is suggestive of a numerical scheme that can be viewed as an extension of the ensemble Kalman filter to a rough-path framework. Finally, we discuss a data-driven method based on subsampling to construct suitable rough path lifts and demonstrate the robustness of our scheme in a number of numerical experiments related to parameter estimation problems in multiscale contexts. ---------------------------------------------------------------------- Gianmarco Bet (he/him) Senior researcher https://gianmarco.bet Phone: (+39) 055 2751491 Department of Mathematics and Informatics "U.

Webinar PRISMA 6 febbraio 23 : Di Crescenzo-Cappelletti
by Claudia Ceci 01 Feb '23

01 Feb '23

Buongiorno a tutte/i, 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) *Lunedi’ 6 febbraio 2023* *ore 16-17 Antonio Di Crescenzo* *Titolo: *You can model so many things with birth-death processes *Abstract:* Birth-death processes constitute the continuous-time analog of random walks, and are largely adopted as a tool for stochastic modeling. Indeed, the richness of the birth and death rates allows modeling a variety of phenomena, ranging from evolutionary dynamics and neuronal modeling, to queueing and reliability theory, for instance. Various methods of analysis have been developed for determining quantities of interest, such as stationary distributions and first-passage-time distributions. The talk is aimed at providing a review of some recent results on growth-evolution models characterized by time-dependent growth rates and their stochastic counterpart described by birth-death processes. The analysis focuses on generalizations of the Gompertz and logistic growth models, and on the related birth-death processes having linear and quadratic rates. A diffusion approximation leading to a time-inhomogeneous geometric Brownian motion is also treated. We also present certain generalizations involving extended birth-death processes on a star-graph defined as a lattice formed by the integers of semiaxes joined at the origin. Specifically, we deal with (i) the analysis of the transient and asymptotic behavior of a multispecies birth-death-immigration process and of a continuous-time multi-type Ehrenfest model, (ii) the construction and the study of suitable diffusion approximations for the considered models, leading to two processes belonging to the class of Pearson diffusions on the spider. *ore 17-18* *Daniele Cappelletti* *Titolo: * Solving the chemical recurrence conjecture in two dimensions *Abstract:* Stochastic reaction networks are continuous-time Markov chains typically used in biology, epidemiology, and population dynamics. The goal is to keep track of the abundance of the different reactants over time. What makes them special from a mathematical point of view is the fact that their qualitative dynamics is described by a finite set of allowed transformation rules, referred to as "reaction graph". A long-standing conjecture is that models with a reaction graph composed by a union of strongly connected components are necessarily positive recurrent, meaning that each single state is positive recurrent. In my talk I will discuss why the conjecture makes intuitive sense and why it is difficult to prove it. I will then show how my collaborators and I adapted Forster-Lyapunov techniques to prove the conjecture in two dimensions.

SPASS Seminar: Dejun Luo
by Francesco Grotto 30 Jan '23

30 Jan '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Convergence rates and CLT for stochastic inviscid Leray-model with transport noise* *Dejun Luo* (Chinese Academy of Science) The seminar will take place on TUE, 31.1.2023 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: * *The stochastic inviscid Leray- model perturbed by multiplicative transport noise is considered on the torus. Under a suitable scaling of the noise, it is shown that the weak solutions converge, in some negative Sobolev spaces, to the unique solution of the deterministic viscous Leray- model. Interpreting such limit result as a law of large numbers, we also study the underlying central limit theorem and provide an explicit convergence rate. This talk is based on a joint work with PhD Bin Tang.*

Seminario Prof. E. Ronchetti

24 Jan '23

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 31 gennaio ore 16.30 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Title: *An Introduction to Saddlepoint Approximations* *Prof. Elvezio Ronchetti* Research Center for Statistics and Geneva School of Economics and Management University of Geneva, Switzerland Elvezio.Ronchetti(a)unige.ch www.unige.ch/gsem/en/research/faculty/honorary-professors/elvezio-ronchetti/ Abstract: Classical inference in statistics is typically carried out by means of standard (first-order) asymptotic theory. However, the asymptotic distribution of estimators and test statistics can provide a poor approximation of tail areas especially when the sample size is moderate to small. This can lead to inaccurate p-values and confidence intervals. Several techniques, both parametric and nonparametric, have been devised to improve first-order asymptotic approximations, including e.g. Edgeworth expansions, Bartlett's corrections, and bootstrap methods. Here we focus on saddlepoint techniques, introduced into statistics by H. Daniels, and more generally on small sample asymptotic techniques, an expression coined by F. Hampel to express the spirit of these methods. Indeed they provide very accurate approximations of tail probabilities down to small sample sizes and /or out in the tails. Moreover, these approximations exhibit a relative error of order 1/n, an improvement with respect to other available approximations obtained by means of Edgeworth expansions and similar techniques. We will review the basic ideas, show the link with other nonparametric methods such as empirical likelihood, and outline some connections to information theory and optimal transportation. ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1INut-6sD210FwZ437k3ydQA5P3xchdIr/view?usp=…> Seminari Matematici Statistici <https://sites.google.com/uniupo.it/seminari-ms/home-page> ----------------------------------- Tutti gli interessati sono invitati a partecipare.

23 Jan '23

We announce the following seminar (held only in person): 26/01/2023 at 12:00 Bocconi University, Via Roentgen 1, Milan Room 3-B3-sr01, floor 3 Speaker: Olga Klopp (ESSEC and CREST). Personal webapge: http://kloppolga.perso.math.cnrs.fr/ Title: Optimality of Variational Inference for Stochastic Block Model Abstract: Variational methods are extremely popular in the analysis of network data. Statistical guarantees obtained for these methods typically provide asymptotic normality for the problem of estimation of global model parameters under the stochastic block model. In the present work, we consider the case of networks with missing links that is important in application and show that the variational approximation to the maximum likelihood estimator converges at the minimax rate. This provides the first minimax optimal and tractable estimator for the problem of parameter estimation for the stochastic block model. We complement our results with numerical studies of simulated and real networks, which confirm the advantages of this estimator over current methods.

IEEE MetroLivEnv 2023 - Special Session PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY
by Antonella Iuliano 20 Jan '23

20 Jan '23

Dear Colleagues, we would like to draw your attention to the upcoming 2023 IEEE INTERNATIONAL WORKSHOP ON METROLOGY FOR LIVING ENVIRONMENT that will be held at the Politecnico di Milano, (Italy), 29 - 31 May, 2023. The following Special Session is open to receive your submissions. PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY The application of metrology related to living environment plays an important role in many applicative contexts to understand and identify sources of variability and to minimise their influence. There is a lack of probabilistic and machine learning approaches in this field; therefore this session aims at covering this aspect. Probability Theory and Statistics provide powerful tools for the development of new mathematical models to describe real life phenomena. One of the most significant advantages of the probabilistic modeling is that it gives a comprehensive understanding of the uncertainty associated with a measurement result. Therefore, the goal of this session is to gather recent advancements with promising future perspectives on the application of mathematical models, in areas such as health care and environmental, to improve the quality of life. Website: https://www.metrolivenv.org/special-session-4 *Important deadlines:* *Extended Abstract Submission Deadline* January 31, 2023 *Extended Abstract Acceptance Notification* March 15, 2023 *Final Paper Submission Deadline* April 15, 2023 *Conference Dates* May 29-31, 2023 For further information and updates please visit the conference website: https://www.metrolivenv.org/ We are looking forward to Welcome you in Milan! Do not hesitate to forward this message to anyone who could be interested. Thank you very much for your kind consideration, and apologies for multiple copies. We look forward to hearing from you.

Seminario Prof. Leonenko
by Enrica Pirozzi 19 Jan '23

19 Jan '23

**** AVVISO di SEMINARIO Prof. Nikolai Leonenko School of Mathematics, Cardiff University, UK TITOLO: Limit theorems for the first Minkowski functional of Gaussian spatiotemporal random fields with long-memory Abstract The paper [1] addresses the asymptotic analysis of sojourn functionals of spatiotemporal Gaussian random fields with long-range dependence (LRD) in time also known as long memory. Specifically, reduction theorems are derived for local functionals of nonlinear transformation of such fields, with Hermite rank m ? 1, under general covariance structures. These results are proven to hold, in particular, for a family of non?separable covariance structures belonging to Gneiting class. For m = 1, under some general condition on covariance structure of spatiotemporal random field with long memory in time, the properly normalized first Minkowski functional converge in distribution to the normal law. For m = 2, under separability of the spatiotemporal covariance function in space and time, the properly normalized Minkowski functional, involving the modulus of a Gaussian random field, converges in distribution to the Rosenblatt type limiting distribution for a suitable range of the long memory parameter. Some other related results can be found in [2,3]. For spatiotemporal isotropic stationary fields on sphere similar results obtained in Marinucci et al. [4] This is joint results with M.D.Ruiz-Medina (Granada University, Spain).

18 Jan '23

Dear colleagues, We are happy to announce the following *hybrid - that is, in person with online streaming - *talks: Speaker: *Eliseo Luongo* (SNS Pisa) *Title:* A stochastic particle approximation approach of the 2D Navier-Stokes equations with vorticity generation. (See Abstract below.) Speaker: *Francesco Grotto *(Univ. di Pisa) *Title:* Area Excursions and nodal Leray measures for Random Waves on hyperbolic space. (See Abstract below.) Date and Time: *Monday January 23, 14:30-16:30 (Rome time zone)* Place: *Aula 3014,* *Dip. di Matematica e Applicazioni, Univ. di Milano-Bicocca*, via R. Cozzi 55, Milano *Webex link:https://unimib.webex.com/unimib-it/j.php?MTID=m4a814f4cfe7e7a7ace5ef5e… <https://unimib.webex.com/unimib-it/j.php?MTID=m4a814f4cfe7e7a7ace5ef5e4d3f6…>* *Meeting number:* 2743 324 2093 *Password:*YPiMid9rP83 *-* *Abstract (Luongo)*: Particle approximation of 2D Navier-Stokes equations is a relevant problem in fluid dynamics with consequences also in its numerical analysis. The problem is essentially solved in the case of domains without boundary, but it remains mostly open in the case of no-slip boundary conditions, due to the difficulty of understanding and modeling generation of vorticity close to the boundary. The solution of this problem could have a deep impact in our understanding of turbulence. In this talk we present a stochastic particle approximation method which allows us to treat 2D Navier-Stokes equations in the case of prescribed vorticity generation. Our approach is almost completely functional analytic based. Moreover we obtain finer convergence results to the solution of the Navier-Stokes equations compared to propagation of chaos techniques. The talk is based on a joint work with F. Grotto and M. Maurelli. *Abstract (Grotto):* Focusing on the asymptotic behavior of a couple of relevant geometric functionals, we will discuss analogies and differences between random wave models on hyperbolic space and other geometric settings on which the related theory is by now well-established. Based on joint work with Giovanni Peccati. - These talks are part of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico.

Seminar in Statistics - ANGELIKA ROHDE

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 20 Gennaio 2023, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Angelika Rohde* (University of Freiburg) Title: *Estimating functionals under local differential privacy* Abstract: We study the problem of estimating a functional $\theta(\mathbb{P})$ of an unknown probability distribution $\mathbb{P} \in\mathcal{P}$ in which the original iid sample $X_1,\dots, X_n$ is kept private even from the statistician via an $\alpha$-local differential privacy constraint. Let $\omega_{TV}$ denote the modulus of continuity of the functional $\theta$ over $\mathcal{P}$ with respect to total variation distance. For a large class of loss functions $l$ and a fixed privacy level $\alpha$, we prove that the privatized minimax risk is equivalent to $l(\omega_{TV}(n^{-1/2}))$ to within constants, under regularity conditions that are satisfied, in particular, if $\theta$ is linear and $\mathcal{P}$ is convex. Our results complement the theory developed by Donoho and Liu (1991 Ann. Statist. 19 633–667) with the nowadays highly relevant case of privatized data. Somewhat surprisingly, the difficulty of the estimation problem in the private case is characterized by $\omega_{TV}$, whereas, it is characterized by the Hellinger modulus of continuity if the original data $X_1,\dots, X_n$ are available. We also find that for locally private estimation of linear functionals over a convex model a simple sample mean estimator, based on independently and binary privatized observations, always achieves the minimax rate. In particular, over the larger class of so-called sequentially interactive privacy mechanisms, a non-interactive procedure attains this rate. Next, we turn to one of the most studied non-linear functionals, the quadratic functional. Here, in contrast, we show that for estimating the integrated square of a density, sequentially interactive privacy mechanisms improve substantially over the best possible non-interactive procedure in terms of minimax rate of estimation. In particular, in the non-interactive scenario we identify an elbow in the minimax rate at $s=3/4$, whereas in the sequentially interactive scenario the elbow is at $s=1/2$. This is markedly different from both, the case of direct observations, where the elbow is well-known to be at $s=1/4$, as well as from the case where Laplace noise is added to the original data, where an elbow at $s=9/4$ is obtained. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/89240989650?pwd=eVZSTUVEWHM2SnhBWXpnL21VU3gvQT09> 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/>

Seminario Paolo Dai Pra
by Enrica Pirozzi 11 Jan '23

11 Jan '23

AVVISO di SEMINARIO Prof. Paolo Dai Pra Università di Verona TITOLO Polarization and Coherence in Mean Field Games Driven by Private and Social Utility Abstract We study a mean field game in continuous time over a finite horizon, T, where the state of each agent is binary and where players base their strategic decisions on two, possibly competing, factors: the willingness to align with the majority (conformism) and the aspiration of sticking with the own type (stubbornness). We also consider a quadratic cost related to the rate at which a change in the state happens: changing opinion may be a costly operation. Depending on the parameters of the model, the game may have more than one Nash equilibrium, even though the corresponding N- player game does not. Moreover, it exhibits a very rich phase diagram, where polarized/unpolarized, coherent/incoherent equilibria may coexist, except for T small, where the equilibrium is always unique. We fully describe such phase diagram in closed form and provide a detailed numerical analysis of the N-player counterpart of the mean field game. Joint work with Marco Tolotti (Venezia) and Elena Sartori (Padova). Il seminario si terrà il giorno 13 Gennaio 2023 ore 11:00 nella Aula F del Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli.

Annuncio Seminario Sapienza // Martedì 10 Gennaio // Lorenzo Dello Schiavo
by Lorenzo Taggi 09 Jan '23

09 Jan '23

Martedì 10 Gennaio 2023, ore 14:00 Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker: *Lorenzo Dello Schiavo (ISTA, Vienna) *Titolo:* Scaling Limits of Random Walks, Harmonic Profiles, and Stationary Non-Equilibrium States in Lipschitz Domains *Abstract:* We consider the open symmetric exclusion (SEP) and inclusion (SIP) processes on a bounded Lipschitz domain Ω, with both fast and slow boundary. For the random walks on Ω dual to SEP/SIP we establish a functional-CLT-type convergence to the Brownian motion on Ω with either Neumann (slow boundary), Dirichlet (fast boundary), or Robin (at criticality) boundary conditions. We further show the discrete-to-continuum convergence of the corresponding harmonic profiles. As a consequence, we rigorously derive the hydrodynamic and hydrostatic limits for SEP/SIP on Ω, and analyze their stationary non-equilibrium fluctuations. Based on joint work arXiv:2112.14196 with Lorenzo Portinale (IAM Bonn) and Federico Sau (ISTA)

seminar on January 11, 2023 - Giulia Di Nunno - Reminder
by Emanuela Rosazza Gianin 07 Jan '23

07 Jan '23

Dear all, you are all invited to participate to the following seminar on *Wednesday 11th of January 2023 at 16:30* in Aula Seminari 4026 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 4th floor): Speaker: *Giulia Di Nunno* (University of Oslo) Titolo: *Sandwiched Volterra volatility models and hedging* Abstract: We present the Sandwiched Volterra Volatility (SVV) model and we discuss some of its characteristic properties. We then move to consider hedging and consider the explicit computation of quadratic hedging strategies. While 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. Best wishes, Emanuela ****************************************** Emanuela Rosazza Gianin Department of Statistics and quantitative methods University of Milano-Bicocca Via Bicocca degli Arcimboldi, 8 20126 Milano - Italy Phone (0039) 02 64483208 e-mail: emanuela.rosazza1(a)unimib.it ******************************************

SPASS Seminar: Antonio Agresti - TUE 10.01 at 14:00
by Andrea Agazzi 04 Jan '23

04 Jan '23

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *The primitive equations with transport noise* by Antonio Agresti (ISTA - Institute of Science and Technology Austria) The seminar will take place in person on *TUE, 10.01.2023 at 14:00 CET* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Title: **The primitive equations with transport noise* *Abstract: **The primitive equations are one of the fundamental models for geophysical flows used to describe oceanic and atmospheric dynamics. In this talk I will discuss some recent results on the primitive equations with noise of transport type. In addition to transport noise, we also consider non-isothermal turbulent pressure. The dependence of the turbulent pressure on the temperature is a consequence of a stochastic Boussinesq approximation. For the primitive equations with transport noise and non-isothermal turbulent pressure, we provide a physical derivation and we discuss the global well-posedness for data in the critical spaces $H^1$. The latter result gives a non-trivial extension of the celebrated work by C. Cao and E.S. Titi on the deterministic model. Our approach is based on recent developments of maximal regularity techniques in the context of stochastic parabolic PDEs. If time allows, then I will also discuss further results in presence of rough noise.* *Based on joint works with M. Hieber (TU Darmstadt), A. Hussein (TU Kaiserslautern) and M. Saal (TU Darmstadt).*

Postdoctoral position at the University of Torino
by Matteo Ruggiero 28 Dec '22

28 Dec '22

Con preghiera di diffusione ai potenziali interessati ----------------------------------------------- Postdoctoral position at the University of Torino Project title: CONSTRUCTION, CHARACTERIZATION AND INFERENCE FOR DIFFUSIONS IN STOCHASTIC POPULATION DYNAMICS Project supervisor: Matteo RUGGIERO (University of Torino and Collegio Carlo Alberto) www.matteoruggiero.it <https://www.google.com/url?q=http://www.matteoruggiero.it&source=gmail-imap…> Brief description (the focus of the project can be adapted to the position holder’s background): The project aims at constructing new diffusion processes for modelling temporally evolving vectors of frequencies and to investigate appropriate inferential strategies when these are seen as hidden Markov models. These processes typically take values on multi-dimensional or infinite-dimensional simplices, and their temporal mechanisms, often related to evolutionary forces used in stochastic population dynamics, typically have commonly used prior distributions in Bayesian statistics as stationary measures. The construction of such models will be achieved by means of approximating sequences of Markov chains after appropriate rescaling, and inference will be tackled exploiting the existence of certain dual processes through particle filtering or Markov chain Monte Carlo methods.

22 Dec '22

Dear all, you are all invited to participate to the following seminar on *Wednesday 11th of January 2023 at 16:30* in Aula Seminari 4026 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 4th floor): Speaker: *Giulia Di Nunno* (University of Oslo) Titolo: *Sandwiched Volterra volatility models and hedging* Abstract: We present the Sandwiched Volterra Volatility (SVV) model and we discuss some of its characteristic properties. We then move to consider hedging and consider the explicit computation of quadratic hedging strategies. While 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.

Padova Seminars in Probability and Finance - Simone Floreani (University of Oxford)
by Alberto Chiarini 16 Dec '22

16 Dec '22

Dear Colleagues, We would like to invite you to the "Padova Seminars in Probability and Finance seminar" that will take place on December 21st at 11.00 in Padova in room 2AB45 at the department of Mathematics “Tullio Levi-Civita". The seminar will be held in person and online via the Zoom platform. _____________________________________________________ Speaker: Simone Floreani (University of Oxford) Title: Hydrodynamics for the partial exclusion process in random environment via stochastic duality Date and time: Wednesday, DECEMBER 21st at 11.00 Place: room 2AB45 at the Department of Mathematics, University of Padova Zoom link: https://unipd.zoom.us/j/88295505400 available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: In this talk, I present a partial exclusion process in random environment, a system of random walks where the random environment is obtained by assigning a maximal occupancy to each site of the Euclidean lattice. This maximal occupancy is allowed to randomly vary among sites, and partial exclusion occurs. After recalling some results on the Bouchaud's trap model, I will show that, when assuming that the maximal occupancies are heavy tailed and i.i.d., the hydrodynamic limit of the particle system is the fractional-kinetics equation. The strategy of the proof is based on stochastic duality, a useful tool in probability theory which allows to study a Markov process (the one that interests you) via another one, called dual process, which is hopefully simpler. In the final part of the talk, I will focus on how some duality relations can be obtained in a more general framework.

Dear all, you're invited to the seminar that will take place, in hybrid mode, at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca. More details: 21st of December 2022, h 16:30, Aula seminari 4026, Building U7, 4th floor Department of Statistics and Quantitative Methods, University of Milano-Bicocca Webex Link: https://unimib.webex.com/unimib/j.php?MTID=mcd5a40a675fd6136e8c3be8a8ead4143 Join by meeting number Meeting number (access code): 2742 148 3807 Meeting password: x3765HJJdRf (93765455 from phones) Speaker: Salvatore Scognamiglio Title: ''Deep learning models for longevity risk'' Abstract: In recent decades, the mortality rates of most developed countries have been gradually declining due to improvements in public health, medical advances, lifestyle changes and government regulation. Although longevity improvement is an obvious benefit for society, it could also represent a risk for governments and insurance companies. Indeed, they could get in financial trouble if they do not adequately consider these longevity improvements for retirement planning and life insurance product pricing. The risk that future mortality and life expectancy outcomes turn out differently than expected is typically called longevity risk, and its management requires stochastic mortality projection models. We introduce a neural network (NN) to fit the Lee-Carter models and some of its extensions on multiple populations. The NN architecture is specifically designed to calibrate each individual model using all available information instead of using a population-specific subset of data as in the traditional estimation schemes. An extensive set of numerical experiments performed on all the countries of the Human Mortality Database shows the effectiveness of our approach. In particular, the resulting parameter estimates appear smooth and less sensitive to the random fluctuations often present in the mortality rates’ data, especially for low-population countries. In addition, the forecasting performance results significantly improved as well.

Martedì 20 Dicembre, ore 14:00, Sapienza Università di Roma, Dipartimento di Matematica, Sala di Consiglio *Speaker: *Giacomo Greco (Eindhoven University of Technology TU/e) *Titolo:* Travelling through turnpikes in the Kinetic Schrödinger Problem *Abstract:* The Schrödinger problem consists in finding the most likely evolution of a system of i.i.d. particles, conditionally on their initial and final configurations. In the last decade this problem has become more and more popular, thanks to its connections with stochastic optimal control theory and optimal transport. In this talk we are going to introduce a Schrödinger problem where the particles follow an (underdamped) Langevin dynamics (i.e. their density satisfies the kinetic Fokker-Planck equation) and where we are given only a partial observation of the initial and final configurations. Then, we will investigate the long-time behaviour of this kinetic system, proving that its most likely evolution is exactly the one that spends most of the time exponentially close to the equilibrium configuration (this property is commonly known in stochastic control theory as the turnpike property). Based on the paper Electron. J. Probab. 27: 1-32 (2022). DOI: 10.1214/22-EJP850

Seminar by A. Awerkin in Padova (Friday 16.12.2022)
by Giorgia Callegaro 13 Dec '22

13 Dec '22

Dear all, you're invited to the next seminar in Probability and Finance, that will take place on Friday 16th December, at 15.30, in hybrid mode at the Mathematics Department of the University of Padova. More details: * *Speaker*: *Almendra Awerkin* (Università di Brescia) * *Date and time*: 16th December 2022, 3.30 pm * *Room (Torre Archimede)*: room 702 * *Zoom link*: please find it at https://www.math.unipd.it/~bianchi/seminari/ * *Title*: *Optimal investment and fair sharing rules of the incentives for renewable energy communities * * *Abstract*: In order to face climate and energy objectives, as reduction of GHG emission and energy independency, countries start to promote sustainable energy plans. In the research for solutions to achieve such goals, Renewable Energy Communities (REC) start to play an important role. A REC is defined as a cooperative, non-profit organization of final customers, which can involve different stakeholders, such as municipalities, local societies, public and private companies, with the purpose of self-producing and self-consuming energy from renewable sources. Recently, the Italian government introduced an incentive tariff for REC. The special feature of this tariff is that it rewards the shared energy from the installation of new renewable sources. Shared energy is defined as the demand of the community which is satisfied by the self-production of energy. In this context, two relevant problems have to be solved: the optimal investment in new technologies and a fair division of the incentive among the community members. In this talk we address this problem by modeling an energy community as a static leader follower problem, where the leader, which can be understood as the administrator or coordinator of the REC, decides the percentage of the incentive that correspond to each member of the community, while the followers, represented by the members of the community, decide how much initially invest in new renewable energy production. We identified the optimal division of the incentive (leader) with a Nash bargaining solution. Additionally, we supposed a competitive game between the community members (followers) and we identified the initial optimal investment solution with a Nash equilibrium. We finish the talk by presenting some extension of our model, partial results and work in progress related to the optimal investment and management of energy communities.

LUISS Math Seminars: Katia Colaneri, Thursday 15 December
by Alessandro Calvia 13 Dec '22

13 Dec '22

Dear all, I am pleased to announce the next seminar in the LUISS math seminars series. Speaker: Katia Colaneri, Università di Roma Tor Vergata. Title: Some Optimisation Problems in Insurance with a Terminal Distribution Constraint. Abstract: We study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a certain target distribution. First, we allow the insurance company to pay dividends and seek to maximise the expected discounted dividend payments or to minimise the ruin probability under the terminal distribution constraint that the surplus is Gaussian with given mean and variance. Here, we find explicit expressions for the optimal strategies in both cases, when the dividend strategy is updated at discrete points in time and continuously in time. Second, we let the insurance company buy a reinsurance contract for a pool of insured or a branch of business. In this setting we only allow for piecewise constant reinsurance strategies producing a normally distributed terminal surplus, whose mean and variance lead, e.g. to a given Value-at-Risk at some confidence level alpha. We investigate the question which admissible reinsurance strategy produces a smaller ruin probability, if the ruin-checks are due at discrete deterministic points in time. This presentation is based on an joint work with Julia Eisenberg (TU Vienna) and Benedetta Salterini (Univ. of Firenze) The seminar will take place on Thursday, 15 December at 12:00 PM in Room A202 - viale Romania 32, Roma.

Still, its learning mechanism is often too simplistic and many generalizations have been proposed to increase its flexibility, a popular one being the class of normalized completely random measures. Here we investigate a simple yet fundamental matter: will a different prior actually guarantee a different learning outcome? To this end, we develop a new framework for assessing the merging rate of opinions based on three leading pillars: i) the investigation of identifiability of completely random measures; ii) the measurement of their discrepancy through a novel optimal transport distance; iii) the establishment of general techniques to conduct posterior analyses, unravelling both finite-sample and asymptotic behaviour of the distance as the number of observations grows. Our findings provide neat and interpretable insights on the impact of popular Bayesian nonparametric priors, with very mild assumptions on the data-generating process. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/84498069342?pwd=ZkJOcnlNalEybmlEdE1QUGFEczZmdz09> 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/>

(PMS)^2 talk - Mario Maurelli - December 13 at 17.30
by Margherita Zanella 07 Dec '22

07 Dec '22

Dear colleagues, We are happy to announce the following online talk: Speaker: Mario Maurelli(Università di Pisa). Title: A McKean-Vlasov SDE and particle system with interaction from reflecting boundaries. Abstract: We consider a one-dimensional McKean-Vlasov SDE on a domain and the associated meanfield interacting particle system. The peculiarity of this system is the combination of the interaction, which keeps the average position prescribed, and the reflection at the boundaries; these two factors make the effect of reflection non local. We show path-wise well-posedness for the McKean-Vlasov SDE and convergence for the particle system in the limit of large particle number. Joint work with Michele Coghi, Wolfgang Dreyer, Peter K. Friz, Paul Gajewski, Clemens Guhlke. Date and time: Tuesday December 13, 17:30-18:30 (Rome time zone) Link: Entra nella riunione in Zoom https://polimi-it.zoom.us/j/92900386273?pwd=dG1xTUtsN0JpaFl2TWlzRTJ1a0lBZz09 ID riunione: 929 0038 6273 Passcode: 638099 This talk is part of the (PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico.

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 14 dicembre ore 16.00 - aula 203, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Dott. Roberto Ascari Università di Milano-Bicocca Title: The flexible Latent Dirichlet Allocation Abstract: Over recent years, text modeling techniques have been employed in several applications, including the detection of latent topics in text documents. A widespread statistical tool for topic modeling is the Latent Dirichlet Allocation (LDA), which allows for a document representation in terms of topic composition. A well-known limitation of the LDA is related to the stiffness of the Dirichlet prior imposed on the topic distributions. To consider a richer dependence structure, we propose a generalization of the Dirichlet distribution as an alternative distribution, namely the flexible Dirichlet (FD). The FD is a distribution defined on the simplex space allowing for a finite mixture structure. This choice introduces additional parameters in the LDA, and ensures more flexibility, still maintaining the model interpretability, as well as conjugacy to the multinomial model. The latter property allows for a Collapsed Gibbs Sampling-based estimation procedure. The generalization of the LDA based on the FD distribution is illustrated via an application to a real dataset. ----------------------------------- Tutti gli interessati sono invitati a partecipare.

Seminar Wager @Bocconi - 12Dec at 12:00
by Giacomo Zanella 06 Dec '22

06 Dec '22

We are glad to announce the following hybrid seminar: Monday, 12 of December 2022 at 12:00 In person: Room 3-E4-SR03, floor 3, Bocconi University, Via Roentgen 1, Milan Zoom link: https://unibocconi-it.zoom.us/j/95882011831; Meeting ID: 958 8201 1831 Speaker: Stefan Wager (Stanford University) Title: Learning from a Biased Sample Abstract: The empirical risk minimization approach to data-driven decision making assumes that we can learn a decision rule from training data drawn under the same conditions as the ones we want to deploy it under. However, in a number of settings, we may be concerned that our training sample is biased, and that some groups (characterized by either observable or unobservable attributes) may be under- or over-represented relative to the general population; and in this setting empirical risk minimization over the training set may fail to yield rules that perform well at deployment. Building on concepts from distributionally robust optimization and sensitivity analysis, we propose a method for learning a decision rule that minimizes the worst-case risk incurred under a family of test distributions whose conditional distributions of outcomes Y given covariates X differ from the conditional training distribution by at most a constant factor, and whose covariate distributions are absolutely continuous with respect to the covariate distribution of the training data. We apply a result of Rockafellar and Uryasev to show that this problem is equivalent to an augmented convex risk minimization problem. We give statistical guarantees for learning a robust model using the method of sieves and propose a deep learning algorithm whose loss function captures our robustness target. We empirically validate our proposed method in simulations and a case study with the MIMIC-III dataset. Best regards, Giacomo Zanella

Corso Marta CATALANO (University of Warwick)
by Matteo Ruggiero 05 Dec '22

05 Dec '22

Cari colleghi, nell’ambito del programma di Visiting Professors della Laurea Magistrale in Stochastics and Data Science dell’Università di Torino (il programma completo è consultabile alla pagina https://www.master-sds.unito.it/go/visiting), con piacere annunciamo il seguente corso: -------------------------------------- MARTA CATALANO (University of Warwick) DEPENDENT NONPARAMETRIC PRIORS VIA COMPLETELY RANDOM MEASURES Bayesian nonparametrics provides a natural framework for performing flexible inference with principled quantification of uncertainty. The main ingredients are discrete random measures, whose laws act as prior distribution for infinite-dimensional parameters and, combined with the data, provide their posterior distribution. Recent works use dependent random measures to perform simultaneous inference across multiple samples. The borrowing of strength across different samples is regulated by the dependence structure of the random measures, with complete dependence corresponding to maximal sharing of information and fully exchangeable observations. In these lectures we start from the notion of completely random measure and describe several ways of introducing dependence between them. Different models may still induce the same amount of borrowing of information, measured by an index of dependence. In the two sample case, this is often achieved by second order summaries of the joint distribution through linear correlation. In the multivariate scenario, we characterise dependence in terms of distance from exchangeability by relying on optimal transport. This allows for informed prior elicitations and provides a fair ground for model comparison. -------------------------------------- Il corso si svolgerà solo in presenza secondo il seguente calendario Lez 1: mar 13/12: 14-16 - Aula 4 Lez 2: mer 14/12: 9.15-11.15 - Aula 4 Lez 3: mer 14/12: 14-16 - Aula 30 Lez 4: gio 15/12: 14-16 - Aula 11 Sede dei corsi: Corso Unione Sovietica 218/bis, 10134, Torino Il corso è rivolto agli studenti della Laurea Magistrale ma la partecipazione è aperta a tutti gli interessati.

Seminario Sapienza - Alberto Chiarini - Martedì 6 Dicembre
by Lorenzo Taggi 30 Nov '22

30 Nov '22

Titolo: On the cost of covering a fraction of a macroscopic body by a simple random walk. Abstract: In this talk we aim at establishing large deviation estimates for the probability that a simple random walk on the Euclidean lattice (d>2) covers a substantial fraction of a macroscopic body. It turns out that, when such rare event happens, the random walk is locally well approximated by random interlacements with a specific intensity, which can be used as a pivotal tool to obtain precise exponential rates. Random interlacements have been introduced by Sznitman in 2007 in order to describe the local picture left by the trace of a random walk on a large discrete torus when it runs up to times proportional to the volume of the torus, and has been since a popular object of study. In the first part of the talk we introduce random interlacements and give a brief account of some results surrounding this object. In the second part of the talk we study the event that random interlacements cover a substantial fraction of a macroscopic body. This allows to obtain an upper bound on the probability of the corresponding event for the random walk. Finally, by constructing a near-optimal strategy for the random walk to cover a macroscopic body, we discuss a matching large deviation lower bound. The talk is based on ongoing work with M. Nitzschner (NYU Courant). Martedì 6 Dicembre, ore 14:00 Dipartimento di Matematica, Sapienza Università di Roma, Sala di Consiglio Speaker: Alberto Chiarini, Università di Padova

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 6 dicembre ore 16.00 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Prof. Andrea Consiglio Università di Palermo Title: Simulation and Optimization Models to Assess Sovereign Debt Sustainability Abstract: We model sovereign debt sustainability with optimal financing decisions under macroeconomic, financial, and fiscal uncertainty, with endogenous risk and term premia. Using a coherent risk measure we trade off debt stock and flow risks subject to sustainability constraints. We optimize static and dynamic financing strategies and demonstrate economically significant savings from optimal financing compared with simple rules and consols, and find that optimizing the trade-offs can be critical for sustainability. ----------------------------------- Tutti gli interessati sono invitati a partecipare.

[PRISMA] seminari di Antonio Lijoi e Federico Camerlenghi
by Domenico Marinucci 28 Nov '22

28 Nov '22

Care colleghe e colleghi il prossimo incontro del ciclo di seminari del gruppo UMI-Prisma si svolgerà come al solito il primo lunedì del mese, quindi il 5 dicembre dalle 16 alle 18 su piattaforma Teams (link alla fine del messaggio). Parleranno Antonio Lijoi e Federico Camerlenghi (cf. http://www.umi-prisma.polito.it/webinars.html); titoli ed abstract qui sotto: ------------------------------------------------------------------------------------------- Antonio Lijoi, Università Bocconi TITLE: Discrete random structures and Bayesian nonparametric modeling ABSTRACT: Discrete random structures, such as random partitions and discrete random measures, have emerged as effective tools for Bayesian modeling and have fueled exciting advances in density estimation, clustering, prediction, feature allocation and survival analysis. The Dirichlet process (DP) has undoubtedly emerged as a reference model, mostly due to its analytical tractability. Nonetheless, the DP shares also some well-known limitations that have spurred a very lively area of research aiming at the proposal and the investigation of more general and flexible discrete nonparametric priors. The talk will provide a broad overview of such classes of priors and will specifically focus on those obtained as normalization of completely random measures. Characterizations of the induced random partitions and predictive rules will be illustrated and their role in designing computational algorithms for the approximation of Bayesian inferences of interest will be highlighted, both in exchangeable and non-exchangeable settings. Federico Camerlenghi, Milano Bicocca TITLE: Normalized random measures with atoms' interaction ABSTRACT: The seminal work of Ferguson (1973), who introduced the Dirichlet process, has spurred the definition and investigation of more general classes of Bayesian nonparametric priors, with the aim at increasing flexibility while maintaining analytical tractability. Among the numerous generalizations, a fundamental class of random probability measures has been introduced by Regazzini et al. (2003): this is the class of normalized random measures with independent increments (NRMIs). NRMIs are random probability measures with almost surely discrete realizations, defined through the specifications of two ingredients: i) a sequence of unnormalized weights, which are the jumps of a Levy process on the positive real line; ii) a sequence of i.i.d. random atoms from a common base measure. The proposed construction is appealing from a mathematical standpoint, because analytical tractability is preserved, however NRMIs do not allow interaction among atoms, which are supposed to be independent and identically distributed. In some applied frameworks, the i.i.d. assumption could be too restrictive, for instance, in model-based clustering, when they are used as mixing measures in mixture models. To overcome this limitation, we propose a new class of normalized random measures with atoms' interaction. In our construction the atoms come from a finite point process, which is marked with i.i.d. positive weights. Thus, a new class of random probability measures is obtained by normalization. The desired interaction among atoms is then induced by a suitable choice of the law of the point process, which can create a repulsive or attractive behaviour. By means of Palm calculus, we are able to characterize marginal, predictive and posterior distributions for the proposed model. We specialize all our results for several choices of the finite point process, i.e., in the Determinantal, Gibbs and Shot-Noise Cox case.

SPASS seminar: Angelo Lucia - THU 01.12 at 14:00
by Andrea Agazzi 28 Nov '22

28 Nov '22

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Thermalization of 2D Quantum Memories* by Angelo Lucia (Universidad Complutense de Madrid) The seminar will take place in person on *THU, 01.12.2022 at 14:00* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Title: Thermalization of 2D Quantum Memories* *Abstract: **The aim of a quantum memory is to protect an encoded quantum state against errors for long periods of time. Quantum double models are a class of 2D quantum memories proposed by Kitaev, in which the protection from noise is due to the topological properties of the ground state degeneracy.* *Heuristic arguments have long pointed to a weakness of these models against thermal noise processes. In this talk I will present a rigorous estimate on the lifetime of these memories under a noise process modeled by Davies generators which confirms these findings. This estimate is obtained by proving that the spectral gap of the generator is lower bounded by a positive constant uniformly in the system size.*

Padova Seminars in Probability and Finance - Giacomo Greco (Eindhoven University of Technology)
by Alberto Chiarini 27 Nov '22

27 Nov '22

Dear Colleagues, We would like to invite you to the following seminar that will take place on December 2nd at 11.00 in Padova. The seminar will be held in person and online via the Zoom platform. _____________________________________________________ Speaker: Giacomo Greco (Eindhoven University of Technology) Title: Entropic turnpike estimates for the kinetic Schrödinger problem Date and time: Friday, DECEMBER 2nd at 11.00 Place: room 2BC30 at the Department of Mathematics, University of Padova Zoom link: https://unipd.zoom.us/j/86210155315 available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: The kinetic Schrödinger problem consists in finding the most likely evolution of a system of i.i.d. particles driven by the underdamped Langevin dynamics, conditionally on their initial and final spatial configurations. In this model each particle is described both by its position and velocity, but there is no a priori knowledge of the velocities at the initial and final time. We will investigate the long-time behaviour of this kinetic system, proving that its most likely evolution is exactly the one that spends most of the time exponentially close to the equilibrium configuration (this property is commonly known in stochastic control theory as the turnpike property). This short talk is based on a joint work with A. Chiarini, G. Conforti, Z. Ren. With best regards, Alberto Chiarini Department of Mathematics Tullio Levi-Civita Via Trieste 63 35121 Padova Italy

Colloquium by Gady Kozma at Milano-Bicocca, in presence, November 30 at 14:30
by Tal Orenshtein 25 Nov '22

25 Nov '22

Dear all, I am delighted to announce the following Colloquium of The Department of Mathematics and Applications <https://www.matapp.unimib.it/it/eventi/colloquium-del-dipartimento-matemati…>, University of Milano-Bicocca combined with the "Seminario Matematico e Fisico di Milano <https://www.mate.polimi.it/smf/>”. Speaker: Gady Kozma (Weizmann Institute of Science, Rehovot). Title: Harmonic functions on groups. Abstract: The classic Liouville theorem states that any bounded harmonic function on Euclidean space is constant. The same holds for discretely harmonic functions on a lattice. But what happens when the Euclidean lattice is replaced by other graphs, in particular Cayley graphs of groups? We will survey old and new results on relations between geometric and algebraic properties of groups, harmonic functions and probability. Based on joint work with various subsets of Itai Benjamini, Ariel Yadin, Hugo Duminil-Copin, Gidi Amir and Maria Gerasimova. The event will take place on November 30, 2022 at 14.30, in presence, Room 3014, 3rd floor of building U5, University of Milano-Bicocca, Via Roberto Cozzi 55, 20125 Milano. Light refreshments will be served after the talk. Best regards, Tal Orenshtein
