SPASS Seminar: Lucio Galeati
by Andrea Agazzi 10 Jan '24

10 Jan '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *A.e. uniqueness for (stochastic) Lagrangian trajectories for Leray solutions to 3D Navier-Stokes* by Lucio Galeati (EPFL) The seminar will take place on TUE, 16.01.2024 at 14:00 CET in Aula Seminari, Dipartimento di Matematica, UNIPI 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: * *We revisit a result due to Robinson and Sadowski (2009), who first showed a.e. uniqueness of Lagrangian trajectories for admissible weak solutions to $3$D Navier-Stokes, for sufficiently regular $u_0$. We give an alternative proof, based on a newly established asymmetric Lusin-Lipschitz property of Leray solutions, exploited crucially in the arguments from Caravenna-Crippa (2021) and Brué-Colombo-De Lellis (2021). This approach is more robust, requiring no assumptions on $u_0$ and being applicable also to the stochastic characteristics of the system.Finally, if $u_0$ is regular (say $u_0\in H^{1/2}$), then we are able to exploit the diffusive behaviour of stochastic trajectories to further prove that, for any fixed $x_0\in\mathbb{R}^d$, path-by-path uniqueness for the SDE $d X_t = u(t,X_t) d t + d B_t, X|t=0 = x_0$.*

talk Alessandro Doldi 23 gennaio 2024

10 Jan '24

Dear all, you are all invited to participate to the following seminar on *Tuesday 23th of January 2023 at 16:00* in Aula Seminari Demografica 2062 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 2nd floor): Speaker: *Alessandro Doldi* (University of Florence) Titolo: *Collective Arbitrage and the Value of Cooperation* Abstract: The paper aims at extending the classical Arbitrage Pricing Theory to a scenario where N agents engage in financial market investments and are permitted to collaborate through exchanges. Within this framework, we introduce the concepts of Collective Arbitrage and Collective Super-replication. Subsequently, we establish versions of the fundamental theorem of asset pricing and the pricing-hedging duality tailored to this cooperative setting. Illustrative examples demonstrate the advantages of our proposed approach. The novel notions of Collective Arbitrage and Collective Super-replication highlight the pivotal role of cooperation and the multidimensional aspect. Notably, when there is only a single agent involved, the theory reduces to the classical one.

09 Jan '24

Dear colleagues and friends, probability theory is a central research theme at UCL Statistical Science. Our research spans several topics including: coupling, ergodic theory, growth-fragmentation, insurance risk, Lévy processes, optimal transport, point processes, random graphs, random interfaces, processes with reinforcement, scaling limits, and statistical mechanics. All PhD students in probability at UCL Statistical Science will be part of and supported by our group. They will also have the opportunity to interact with closely related areas in statistical theory such as causal inference and Markov chain Monte Carlo. In their first year, new students will have the chance to partake in basic and advanced training in probability and statistics, with the aim that a student in our group will be conversant with the main research in the probability group and will be familiar with the broader research in statistical theory. For more information, interested students are encouraged to contact: Alessandra Cipriani, a.cipriani(a)ucl.ac.uk<mailto:a.cipriani@ucl.ac.uk>; Codina Cotar, c.cotar(a)ucl.ac.uk<mailto:c.cotar@ucl.ac.uk>; Terry Soo, t.soo(a)ucl.ac.uk<mailto:t.soo@ucl.ac.uk>; Alex Watson, alexander.watson(a)ucl.ac.uk<mailto:alexander.watson@ucl.ac.uk>.

talk Prof. Giulia Di Nunno - Reminder
by Emanuela Rosazza Gianin 07 Jan '24

07 Jan '24

Dear all, you are all invited to participate to the following seminar on *Wednesday 10th of January 2023 at 16:00* in Aula Seminari Demografica 2062 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 2nd floor): Speaker: *Giulia Di Nunno* (University of Oslo) Titolo: *Sandwiched Volterra volatility models, power law and option pricing* Abstract: We consider a financial market with stochastic volatility driven by an arbitrary Hölder continuous Gaussian Volterra process. The distinguishing feature of the model is the form of the volatility equation which ensures the solution to be “sandwiched” between two arbitrary functions chosen in advance. Hence the name Sandwiched Volterra Volatility (SVV) model. Targeting option pricing, we discuss the structure of local martingale measures in this market and we develop an algorithm of pricing options with discontinuous payoffs. Our tools rely on the study of Malliavin calculus, indeed the Malliavin differentiability of the equations and prices is studied. With these, we can also study the power law property of the SVV model.
