Seminario on-line PRISMA lunedì 6 ottobre 2025 - C. Franceschini & F. Sau
by Sonia Mazzucchi 25 Sep '25

25 Sep '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. Dallo scorso anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per *lunedì 6 ottobre* 2025. I relatori saranno *Chiara Franceschini* (Università di Modena e Reggio Emilia) e *Federico Sau* (Università di Milano Statale) che parleranno di: *Sistemi interagenti del non-equilibrio: dualità e gap spettrali* 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/83547578084 ID riunione: 835 4757 8084 Codice d’accesso: 873866 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Chiara Franceschini (Università di Modena e Reggio Emilia) e Federico Sau (Università di Milano Statale) TITOLO: Sistemi interagenti del non-equilibrio: dualità e gap spettrali RIASSUNTO: In questo seminario verranno presentati alcuni modelli di sistemi interagenti con spin sia discreti che continui. Tra gli esempi principali figurano il modello di Kipnis-Marchioro-Presutti (1982) e il processo armonico recentemente introdotto. Quando questi modelli sono studiati su un reticolo unidimensionale in contatto con reservoir ai bordi, costituiscono un setting classico per l’analisi di fenomeni tipici della meccanica statistica fuori dall’equilibrio. Tutti i modelli considerati sono associati alla Lie algebra su(1,1) e condividono diverse caratteristiche strutturali, tra cui la proprietà di dualità. Nella prima parte del seminario introdurremo il concetto di dualità per i processi di Markov, illustrando come esso consenta di derivare limiti di scala macroscopici (come l’equazione idrodinamica e i principi di grandi deviazioni) e ottenere informazioni sulla misura stazionaria fuori dall’equilibrio, esplicitamente nota solo per alcuni casi specifici. Nella seconda parte prenderemo in esame modelli definiti anche su grafi arbitrari, focalizzandoci sullo studio del gap spettrale e sulla convergenza all’equilibrio.

QFinLab Seminar - Anna Maria Gambaro (Università del Piemonte Orientale) - 1/10/2025, 12:15 @ Department of Mathematics, Politecnico di Milano
by Alessandro Calvia 25 Sep '25

25 Sep '25

Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Wednesday, 1 October 2025, 12.15-13.15 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Anna Maria Gambaro (Università del Piemonte Orientale) Title: Functional PCA for Risk-Neutral densities in Bayes Hilbert space. Abstract: In this work, we investigate the main drivers of risk-neutral densities of quoted stocks, using the functional principal component analysis (FPCA). To this end, we first construct a historical series of risk-neutral densities corresponding to quoted option prices with fixed time to maturity, using exponential expansions of orthogonal polynomials. Then, we apply the centered log-ratio transformation (CLRT) to the extracted densities and we perform the FPCA in the Bayes–Hilbert space. The CLRT provides an isometric isomorphism between the Bayes space of square log-integrable densities and the classical Hilbert space of square-integrable functions. As a result, the projected data onto the principal component basis correspond to the CLRT-transformed densities, and the application of the inverse CLRT yields proper density functions. Furthermore, by modeling the historical series of FPCA loadings as a stochastic process, we exploit the FPCA representation for forecasting purposes. Finally, we discuss extensions of this framework to cross-asset analyses and to the modeling of option price surfaces. This is a joint work with A. Amici e G. Fusai. Attendance is also possible online (Microsoft Teams), clicking here.<https://teams.microsoft.com/l/meetup-join/19%3ameeting_YmFlY2M5OWEtYzg1OS00…> All news can be found on the QFinLab webpage<https://www.qfinlab.polimi.it/seminars-and-meetings/>.

De Finetti seminar: Huyên Pham and Stéphane Crépey, Sept. 24, 2025
by Alessandro Doldi 22 Sep '25

22 Sep '25

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 Lectures on September 24, 2025: Huyên Pham, Ecole Polytechnique (h. 16:00) and Stéphane Crépey, Université Paris Cité (h. 17:00) LOCATION The seminars will be held on September 24, 2025 starting at 16:00, Aula C20 (Via Colombo 62), Università degli Studi di Milano, Milano. TITLES AND ABSTRACTS Huyên Pham: Bridging Schrödinger and Bass for generative modeling We address the problem of generating a continuous semimartingale that interpolates prescribed initial and terminal distributions. This is formulated as an optimal transport problem that unifies the Schrödinger bridge and Bass martingale frameworks, enabling the construction of a diffusion process that simultaneously calibrates both drift and volatility to observed data. We derive an analytic characterization of the optimal diffusion’s dynamics, called Schrödinger bridge Bass (SBB) Diffusion, and show that it can be expressed as a stretched Brownian motion under an explicit change of measure. We then design a computational resolution of the SBB, offering an efficient framework for generative modeling in applications such as image synthesis and time series generation. Stéphane Crépey: Comparison of Tax and Cap-and-Trade Carbon Pricing Schemes Carbon pricing has become a central pillar of modern climate policy, with carbon taxes and emissions trading systems (ETS) serving as the two dominant approaches. Although economic theory suggests these instruments are equivalent under idealized assumptions, their performance diverges in practice due to real-world market imperfections. A particularly less explored dimension of this divergence concerns the role of financial intermediaries in emissions trading markets. This paper develops a unified framework to compare the economic and environmental performance of tax- and market-based schemes, explicitly incorporating the involvement of intermediaries. By calibrating both instruments to deliver identical emissions reductions, we assess their economic performance across alternative market structures. Our results suggests that, although the two schemes are equivalent under perfect competition, the presence of intermediaries in ETS reduces regulatory revenues and the aggregate profits of financial actors relative to carbon taxation. These effects arise from intermediaries' influence on price formation and their appropriation of part of the revenue stream. The findings underscore the importance of accounting for intermediaries' behavior in the design of carbon markets and highlight the need for further empirical research on the evolving institutional structure of emissions trading systems.
