Dear colleagues, We are happy to announce the opening of applications for the PhD programme in Mathematics, Statistics, and Computer Science at the University of Florence. Applications in Probability are very welcome. See here for the general call: https://www.unifi.it/en/study-us/after-graduation/phd-programmes/phd-course… and here for more specific information about the PhD application in Maths: https://www.unifi.it/en/study-us/after-graduation/phd-programmes/phd-courses A Master’s degree is required, but those who do not hold it yet can be admitted, as long as they get their degree by October. A brief 1-2 page research project is also required during the application; this is usually written in collaboration with a potential supervisor. There are 8 positions not linked to a specific research topic (so any research topic in Mathematics, Statistics and Computer Science is welcome), of which 6 with scholarship and 2 without. Interested people are encouraged to get in touch with one of us.

Eleanor Archer (Dauphine-PSL Paris) A spanning tree of a finite connected graph G is a connected subgraph of G that contains every vertex and no cycles. A well-known result of Aldous states that the scaling limit of the uniform spanning tree (UST) of the complete graph is the Brownian continuum random tree. We will discuss a recent result that shows that this is a universal phenomenon, in that the GHP scaling limit of the UST of any appropriate sequence of high dimensional graphs is the CRT. In particular, this holds for the torus in dimensions five and higher. Based on joint work with Asaf Nachmias and Matan Shalev. Scaling limit of the Aldous-Broder chain on regular graphs: the transient regime. Anita Winter (Duisburg-Essen University) A spanning tree of a finite connected graph G is a connected subgraph of G that contains every vertex and no cycles. A well-known way to generate a uniform spanning tree (UST) is the Aldous-Broder algorithm. This is a stochastic process with values in rooted trees that is driven by a random walk on G and converges as time goes to infinity towards the Brownian Continuum Tree (CRT). On the complete graph it is known that this process has a GH-scaling limit which is referred to as Root Growth with Regrafting dynamics (RGRG). We will show that this is again a universal phenomenon, i.e., it holds for the Alous-Broder chain on any appropriate sequence of regular graphs in the transient regime. In particular, this holds for the torus in dimensions five and higher. This is joint work with Osvaldo Angtuncio Hernandez and Gabriel Berzunza Ojeda. https://polimi-it.zoom.us/j/92945513591?pwd=zjtRwpHoO9kRyQuPPj4o186jXrvg1v.1 Meeting ID: 92945513591 Passcode: 131676

Seminario PRISMA venerdì 6 giugno 2025 - S. Mazzonetto & P. Pigato
by Sonia Mazzucchi 20 May '25

20 May '25

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per *venerdì 6 giugno* 2025. I relatori saranno *Sara Mazzonetto* (Université de Lorraine) e *Paolo Pigato* (Università di Roma 2 “Tor Vergata”) che parleranno di: *Diffusioni a soglia e il ruolo del tempo locale* con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://unitn.zoom.us/j/82271416480 ID riunione: 822 7141 6480 Codice d’accesso: 130382 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Sara Mazzonetto (Université de Lorraine) e Paolo Pigato (Università di Roma 2 “Tor Vergata”) TITOLO: Diffusioni a soglia e il ruolo del tempo locale RIASSUNTO: Le diffusioni a soglia sono soluzioni di equazioni differenziali stocastiche i cui coefficienti cambiano in modo discontinuo a seconda della posizione del processo rispetto a delle barriere (soglie). Sono usate nella modellizzazione di vari fenomeni, in finanza/economia, ingegneria e altre scienze. In questo seminario, daremo un’introduzione a questi processi dal punto di vista matematico e parleremo delle loro applicazioni. Considereremo poi alcuni problemi di inferenza dei parametri, discutendo risultati asintotici sotto diverse ipotesi e sottolineando le difficoltà tecniche provenienti in particolare dalla connessione tra discontinuità, moto browniano skew e tempi locali. .%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Seminari online su applicazioni della probabilità in economia (Save the dates)
by Enrico Scalas 20 May '25

20 May '25

Il gruppo UMI PRISMA organizza una serie di tre seminari online, in inglese, sulle "Applicazioni della Probabilità all’Economia". La serie di seminari è specificamente organizzata da: - Giulio Bottazzi (Scuola Superiore Sant'Anna) - Alessandro Calvia (Politecnico di Milano) - Marco Capaldo (RWTH Aachen) - Enrico Scalas (Sapienza Università di Roma) I seminari sono in preparazione alla Summer School of Mathematics for Economic and Social Sciences: https://indico.sns.it/event/105/overview I dettagli sui link saranno diffusi in prossimità degli eventi sul sito web del gruppo UMI PRISMA: https://umi-prisma.polito.it/ e su questa lista. I seminari saranno i seguenti: 26 giugno 2025 ore 14 Speaker: Marta Leocata, LUISS Guido Carli, Department of AI, Data and Decision Sciences Title: Two applications of multi-agent models in economic and social systems Abstract: In this talk, we present an overview of mathematical models that capture the behavior of myopic agents—who rely on short-term, local information in their decision-making—and strategic agents, who consider the long-term consequences of their actions within interactive environments. These concepts will be illustrated through two applications in economic and social contexts: a multi-agent model for the co-evolution of preferences and actions in the emergence of social norms (joint work with Michele Aleandri, LUISS, and Laura Marcon, CNR), and a Mean Field Game approach to the Emission Trading System (joint work with Giulia Livieri, LSE, and Gianmarco Del Sarto, TU Darmstadt). -- 10 luglio 2025 ore 14 Speaker: Annamaria Olivieri, University of Parma (Italy), Department of Economics and Management Title: Modelling Stochastic Mortality for Life Insurance Applications Abstract: In the closing decade of the last century, a generalized decrease in mortality rates has been reported in many countries, especially at adult and old ages, which was highly unanticipated. Until then, the modelling of mortality for insurance applications was mainly deterministic since, according to the classical insurance paradigm, in sufficiently large and homogeneous pools there is a high probability to achieve an outcome in line with what expected. Uncertain mortality trends are against such an argument. Net of the effect of the pandemic, the decreasing trend in mortality has persisted to current times, at a pace that remains random. Mortality has a clear impact on the liabilities of the life insurance (and pension) industry and an adequate mortality forecasting is among the key elements of an effective risk management design for a life insurer (or a pension fund), especially when longevity benefits are involved. Starting from the end of the last century, stochastic mortality modelling has become a core topic of actuarial science and many studies have greatly enriched the actuarial literature. In this presentation, the main characteristics of mortality trends are first summarized, with particular regard to the Italian population. Then, mortality and longevity risks are defined. Finally, a review of the main stochastic mortality models developed for actuarial purposes is provided. -- 17 luglio 2025 ore 14 Speaker: Sara Merino Aceituno, Faculty of Mathematics, University of Vienna (Austria) Title: Large particle limit for jump processes Abstract: In this short course, we will study interacting particle systems whose dynamics are governed either by continuous-time Markov processes (such as coagulation models) or piecewise deterministic Markov processes (such as run-and-tumble dynamics). Our starting point will be the martingale formulation of these systems. The primary objective is to derive equations that approximate the behavior of the system as the number of particles becomes large.
