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 $d X_t = u(t,X_t) d t + d B_t, X|t=0 = x_0$.*

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.

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.

RTD-A in Mathematical Physics @Unibo
by Giacomo De Palma 06 Jan '24

06 Jan '24

The Department of Mathematics of the University of Bologna has opened a 3-year RTD-A (Assistant Professor) position in Mathematical Physics within the PNRR project SERICS - SEcurity and RIghts in the CyberSpace. Within the next three years the Mathematical Physics group plans to open a tenure-track position. The opening and the application procedure can be found at: https://bandi.unibo.it/s/apos5/bando-per-1-posto-da-rtd-a-tempo-pieno-mat-s… The deadline for application is sharp at 12:00 of 02/02/2024 We are looking for top early-career researchers in the fields of Statistical and Quantum Mechanics. These include but are not limited to areas of complex and disordered systems, spin glasses, classical and quantum neural networks and statistical inference, both from a theoretical perspective and by looking at applications, especially to complex networks. The research activity of the successful candidate will be focused on reliability and risk management in complex systems. The candidate will deal with the introduction of mathematical physics models for complex cyber-physical interconnected systems. The first part of the research activity will be devoted to the introduction of (deterministic and/or stochastic) models describing the topology of the interconnections and their evolution in time, through the theory of complex networks. The second part of the research activity will be dedicated to the study of systemic risk from the point of view of statistical mechanics. The aim is the introduction of new risk measure linked to the emergent macroscopic properties, of efficient techniques for anomaly detection and of exogenous/endogenous strategies of risk mitigation that lead to systems that are more robust to external attacks and internal fluctuations. The University of Bologna is the oldest University in continuous operation in the world and renowned to be one of the best in Italy. The city of Bologna offers a broad number of cultural activities and a high quality of life. The Mathematical Physics Group is active in Statistical Mechanics and Applications (https://math.unibo.it/en/research/research-groups/statistical-mechanics-and…) and Quantum Information Theory (https://math.unibo.it/en/research/research-groups/quantum-information-theory) The Department has a wide spectrum of research interests in all the fields of mathematics: https://math.unibo.it/en/research/research-areas and has close collaborations with the Departments of Physics, Computer Science, Engineering, Economics etc. For further information you are welcome to contact Prof. Pierluigi Contucci, pierluigi.contucci(a)unibo.it<mailto:pierluigi.contucci@unibo.it> Prof. Giacomo De Palma, giacomo.depalma(a)unibo.it<mailto:giacomo.depalma@unibo.it> Prof. Gabriele Sicuro, gabriele.sicuro(a)unibo.it<mailto:gabriele.sicuro@unibo.it> Prof. Daniele Tantari, daniele.tantari(a)unibo.it<mailto:daniele.tantari@unibo.it>
