SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 19 Gennaio 2024, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: Francesca Crucinio (ENSEAE, France) Title: *A connection between tempering and entropic mirror descent* Abstract: This talk explores the connections between tempering (for Sequential Monte Carlo; SMC) and entropic mirror descent to sample from a target probability distribution whose unnormalized density is known. We establish that tempering SMC is a numerical approximation of entropic mirror descent applied to the Kullback-Leibler (KL) divergence and obtain convergence rates for the tempering iterates. Our result motivates the tempering iterates from an optimization point of view, showing that tempering can be used as an alternative to Langevin-based algorithms to minimize the KL divergence. We exploit the connection between tempering and mirror descent iterates to justify common practices in SMC and propose improvements to algorithms in literature. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/85042791274?pwd=V05aejBLYXEyL1lRNURFMUZIcy9PUT09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Seminario di Michele Salvi alla Sapienza, Martedì 16/01/24
by Faggionato, Alessandra 11 Jan '24

11 Jan '24

Buongiorno Martedì 16 Gennaio Michele Salvi terrà un seminario di Probabilità al Dipartimento di Matematica della Sapienza Sotto trovate i dettagli. Grazie per l'attenzione Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Speaker: Michele Salvi (Università di Tor Vergata) Where: Sala di Consiglio, Dip. di Matematica, Sapienza Università di Roma When: Tuesday 16 January, 14:00 (sharp) Title: *From the Uniform to the Minimum Spanning Tree* Abstract: A spanning tree of a graph G is a connected subset of G without cycles. The *Uniform Spanning Tree* (UST) is obtained by choosing one of the possible spanning trees of G at random. The *Minimum Spanning Tree* (MST) is realised instead by putting random weights on the edges of G and then selecting the spanning tree with the smallest weight. These two models exhibit markedly different behaviours: for example, their diameter on the complete graph with n nodes transitions from n^1/2 for the UST to n^1/3 for the MST. What lies in between? We introduce a model of *Random Spanning Trees in Random Environment* (RSTRE) designed to interpolate between UST and MST. In particular, when the environment disorder is sufficiently low, the RSTRE on the complete graph has a diameter of n^1/2 as the UST. Conversely, when the disorder is high, the diameter behaves like n^1/3 as for the MST. We conjecture a smooth transition between these two values for intermediate levels of disorder. This talk is based on joint work with Rongfeng Sun and Luca Makowiec (NUS Singapore). -- ************************************************* Prof. Alessandra Faggionato https://www1.mat.uniroma1.it/people/faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

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

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. Best wishes, Emanuela ****************************************** Emanuela Rosazza Gianin Dipartimento di Statistica e Metodi Quantitativi Università di Milano-Bicocca Via Bicocca degli Arcimboldi, 8 20126 Milano Tel. 02 64483208 e-mail: emanuela.rosazza1(a)unimib.it ******************************************
