(PMS)^2 talk - D. Kinzebulatov - sept 10 at 14:00
by Carlo Orrieri 06 Sep '24

06 Sep '24

Dear colleagues, we are happy to announce the following talk Damir Kinzebulatov (Université Laval) Recent progress on well-posedness of singular SDEs with critical drifts Abstract: In the first part of the talk, I will review the basic results on SDEs with singular drifts. In the second part, I will discuss some recent progress on weak and strong existence and conditional uniqueness for SDEs with singular drifts having critical-order singularities. These drifts either (a) reach the critical strength of the singularities, i.e. multiplying such a drift by a constant even slightly greater than 1 can destroy the weak existence, or (b) are more singular (not necessarily even in L^{2}_{\loc}(R^{1+d})) and can have critical 1/\sqrt{t} singularities in time. I will be referring to De Giorgi's method in L^p with p chosen sufficiently large (in order to accommodate the strength of the singularities going up to the critical threshold), some "fractional" Duhamel series representations and an appropriate parabolic Adams-Krylov estimate, the method of Röckner-Zhao of constructing strong solutions, and a "critical" Orlicz space with gauge function \cosh - 1 that allows to treat the Kolmogorov operator with the borderline strength of the singularities in the drift where the L^p no longer exists. Date and time: Thursday September 10, 14:00-15:00 (Rome time zone) Place: Aula Beltrami, Dip. Matematica, Univ. Di Pavia. Zoom meeting link: https://unipv-it.zoom.us/j/96306243310?pwd=YahZ15tfGy3iF4SoCc5JoQ5UDxDiDB.1 <https://unipv-it.zoom.us/j/96306243310?pwd=YahZ15tfGy3iF4SoCc5JoQ5UDxDiDB.1> ID riunione: 963 0624 3310 Codice d’accesso: 920516 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 and Milano-Politecnico. Participation is free and welcome! Best regards The organizers (Carlo Orrieri, Maurizia Rossi, Margherita Zanella)

Seminar Professor Michael Benzaquen 26/09 aula mancini@SNS
by Manuel NAVIGLIO 06 Sep '24

06 Sep '24

Dear All, On the morning of Thursday, 26th, we will be hosting a seminar by Professor Michael Benzaquen from École Polytechnique and Capital Fund Management, Paris. The seminar will take place at 10:00 AM in Aula Mancini at Scuola Normale. Attached, you will find the title and abstract of the seminar. Additionally, I would like to remind you that Professor Benzaquen will also give another seminar in the afternoon, as part of the Physics in the AI Era <https://agenda.infn.it/event/40134/> conference, in Aula Stemmi. The title of this seminar is: "Econophysics: Why and What For?". Best regards, Manuel ------------------------------------------------------------------------------------------------- Mitigating Farmland Biodiversity Loss: A Bio-Economic Model of Land Consolidation and Pesticide Use Biodiversity loss driven by agricultural intensification is a pressing global issue, with significant implications for ecosystem stability and human well-being. We design an integrated bio-economic agent-based model, informed by historical data from the French agricultural sector, to project future biodiversity trends and evaluate policy interventions. Our model predicts further biodiversity decline under a business-as-usual scenario, primarily due to intensified land consolidation. We evaluate two policy options: reducing pesticide use and subsidizing small farmers. While pesticide reduction rapidly benefits biodiversity in the beginning, it eventually leads to increased land consolidation and further biodiversity loss. In contrast, subsidizing small farmers by reallocating a small fraction of existing subsidies, stabilizes farm sizes and enhances biodiversity in the long run. The most effective strategy results from combining both policies, leveraging pesticide reduction alongside targeted subsidies to balance economic pressures and consistently improve biodiversity.

Reminder - Workshop LSID24 - Padova, September 18 - 20, 2024
by Alberto Chiarini 04 Sep '24

04 Sep '24

With this message we would like to remind you about the upcoming workshop: Large scale behaviour of interacting diffusions: from stochastic control to functional inequalities Padova, September 18 - 20, 2024 The goal of the workshop is to discuss recent advances on the study of asymptotic properties of interacting particle systems, with a special emphasis on controlled systems. Topics of interest include but are not limited to propagation of chaos, infinite dimensional Hamilton-Jacobi equations and ergodicity. We also aim at fostering discussions on the interplay between control methods and other emerging techniques to establish functional inequalities. SPEAKERS: Luisa ANDREIS (Politecnico Milano) Charles BERTUCCI (École polytechnique Paris) Michele COGHI (Trento) Andrea COSSO (Milano Statale) Samuel DAUDIN (Université Côte d'Azur) Benoit DAGALLIER (Courant Institute, New York) Katharina EICHINGER (École polytechnique Paris) Markus FISCHER (Padova) Richard KRAAIJ (TU Delft) Elisa MARINI (Padova) Mario MAURELLI (Pisa) Pierre MONMARCHÉ (Sorbonne Paris) Carlo ORRIERI (Pavia) Sam POWER (Bristol) Julien REYGNER (École des Ponts Paris) Katharina SCHUH (TU Wien) Yoan TARDY (École polytechnique Paris) Please use the following link for more information about the program and to register for the event (registration is free but mandatory) https://events.math.unipd.it/LSID24/. Thank you for your consideration and we hope to see you in a couple of weeks, the organizers, Alekos Cecchin, Alberto Chiarini, Giovanni Conforti and Alessandra Cipriani

talk Prof. Felix-Benedikt Liebrich - 10 September
by Emanuela Rosazza Gianin 04 Sep '24

04 Sep '24

Dear all, you are all invited to participate to the following seminar on *Tuesday 10th of September 2024 at 16:30* in Aula Seminari Demografica 2062 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 2nd floor): *Speaker: *Felix-Benedikt Liebrich (Univ. of Amsterdam) *Title:* The (?) reference measure *Abstract:* A functional on random variables is law invariant with respect to a reference probability (or probabilistically sophisticated) if its value only depends on the distribution of its argument under that measure. The class of such functionals is not only vast, but of integral importance for financial, actuarial, and economic applications. In this talk, we take a concrete functional as given and ask (i) if there can be more than one such reference probability, and (ii) how one can infer the reference probability from the functional. This stance is in contrast to wide parts of the literature that treat the reference probability as given. Nevertheless, as I will show at the beginning of my talk, it is in line with the investigation of probabilistically sophisticated preferences and arises as a natural consequence of the Marinacci-Svistula Uniqueness Theorem. Concerning question (i), I demonstrate that uniqueness holds for a wide class of functionals unless they are constant or depend only on the essential supremum and essential infimum of the argument. Applications to monetary and return risk measures will be given. Concerning the calibration question (ii), I show how to infer the reference measure as a related supremum or infimum in the space of bounded charges. While this approach is generally versatile, it fails in the important case of the Value-at-Risk. Here, a suitable alternative is presented.
