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.

Event in memory of Errico Presutti / September 30, 2025 / CNR, Rome
by Alessia Nota 22 Sep '25

22 Sep '25

[Apologies for possible cross-postings] Dear Colleagues, This is a kind reminder of the conference ”A special day in Statistical Mechanics and beyond: Remembering Errico Presutti” dedicated to the memory of our colleague, mentor and friend Errico Presutti who left us in December 2024. The conference will take place on September 30, 2025 at the Consiglio Nazionale delle Ricerche (CNR) in Rome. It will consist of few talks in order to allow ample time for discussions on the topics on which Errico was active and innovative such as Equilibrium and Non-equilibrium Statistical Mechanics, Field Theory and Stochastic Processes among others. SPEAKERS: Thierry Bodineau Gioia Carinci Giovanni Gallavotti Stephan Luckhaus Herbert Spohn Note that the registration to the conference is still open and that the event will be streamed online. You can find the link here: https://errico-presutti.mat-univaq.com/schedule-and-link For additional information, please write to the organizers. Please feel free to circulate the announcement and the poster among colleagues and students who may be interested in the event. With best regards, Lorenzo Bertini Roberto Natalini Alessia Nota Mario Pulvirenti Benedetto Scoppola Dimitrios Tsagkarogiannis

Seminar Announcement at Sapienza University of Rome (Esmée Theewis)
by Antonio Agresti 19 Sep '25

19 Sep '25

Dear Colleagues, With this, I would like to advertise the following talk by Esmée Theewis (TU Delft), which will be held at the Math Department of Sapienza University of Rome in "Sala di Consiglio" at *16:00 *on* Monday, September 29th*. Kind regards, Antonio Agresti *Esmée Theewis* (TU Delft) *Title:* Large deviations for SPDEs *Abstract:* This talk is about large deviations for solutions to quasilinear SPDEs with small Gaussian noise. We consider a general variational framework for SPDEs. The large deviation principle (LDP) has been successfully proved for such frameworks by means of the so-called weak convergence approach, but rather strong assumptions must be made on the coefficients in the equation or on the Gelfand triple. In our recently obtained large deviation result, we do not require any additional assumption apart from those required for well-posedness of the equation. This leads to numerous applications for which the LDP was not established yet, such as equations on unbounded spatial domains with gradient noise. In particular, the result solves a long-standing open problem concerning 2D Navier-Stokes. Finally, a generalization of the LDP result will be discussed with a new fluid dynamics application. The talk is based on joint work with Mark Veraar and Antonio Agresti.

SPASS seminar: Michele Coti Zelati
by Mario Maurelli 18 Sep '25

18 Sep '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstract below): *Alpha-unstable flows and the fast dynamo problem* by *Michele Coti Zelati* (Imperial College London) The seminar will take place on *THURSDAY, 25.09.2025* at *09:00 CEST *(mind unusual date and time) in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. Best regards Mario Maurelli https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- *Title: **Alpha-unstable flows and the fast dynamo problem* *Abstract: The fast dynamo problem concerns the generation and maintenance of magnetic fields by fluid motion through the process of electromagnetic induction. In passive vector advection, this can be formulated as the exponential growth of the magnetic energy, at a resistivity-independent rate. In this talk, I will provide a construction of a Lipschitz, divergence-free and time-independent velocity field that is a fast dynamo on the whole space.*

Dear colleagues, the Berlin-Oxford International Research Training Group (IRTG) 2544 “Stochastic Analysis in Interaction” offers 6 PhD positions (75% TVL E 13, about 2100 EUR p.m. after taxes, social security...) for 3 years starting between January 1 and April 1, 2026. Funded by the Deutsche Forschungsgemeinschaft (DFG), the IRTG is a joint research initiative of the stochastic analysis groups at FU, HU, TU and WIAS Berlin with its counterpart at the University of Oxford. The advertised positions will be based in Berlin and will offer ample opportunities to interact also with members of the Oxford team, most notably in a 6-months exchange. Embedded in a truly international environment, the IRTG students will get excellent research training in a structured programme focussing on challenges at the mathematical foundations of Stochastic Analysis as well as on challenges arising from its various applications, e.g., in physics, biology, finance or data science. The combined expertise from the Berlin and Oxford groups will provide a significant breadth in depth and a fertile ground for our students' ambitious research ideas. Successful candidates will have an MSc degree (or equivalent) in Mathematics (or a closely related field), strong knowledge of stochastic analysis, and feel eager to engage in the exchange of ideas with the teams in both Berlin and Oxford. Deadline for applications is November 1, 2025. Please see https://www.jobs.tu-berlin.de/en/job-postings/196875 for the official job ad and for instructions how to apply.
