Seminario PRISMA lunedì 5 maggio 2025 - C. Orrieri & L. Scarpa
by Sonia Mazzucchi 05 May '25

05 May '25

Buongiorno, ricordiamo a tutti gli interessati che oggi lunedì 5 maggio dalle 16 alle 17:17 si svolgerà il periodico seminario online del gruppo UMI-PRISMA. I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb I relatori di oggi pomeriggio saranno Carlo Orrieri (Università di Pavia) e Luca Scarpa (Politecnico di Milano) che parleranno di: Equazioni stocastiche doppiamente nonlineari e relativi problemi di regolarizzazione per rumore con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://unitn.zoom.us/j/88514293418 <https://www.google.com/url?q=https://unitn.zoom.us/j/88514293418&sa=D&sourc…> ID riunione: 885 1429 3418 Codice d’accesso: 236100 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Carlo Orrieri (Università di Pavia) e Luca Scarpa (Politecnico di Milano) TITOLO: Equazioni stocastiche doppiamente nonlineari e relativi problemi di regolarizzazione per rumore RIASSUNTO: Nella prima parte del seminario verranno introdotte alcune classi di equazioni di evoluzione in relazione alla modellizzazione di problemi di transizione di fase. Dal punto di vista matematico tali equazioni sono caratterizzate da una dinamica doppiamente nonlineare che tipicamente non ne assicura la buona positura. In particolare, l’unicità delle soluzioni viene a mancare. Questo motiva l’introduzione e l'analisi di opportune formulazioni stocastiche per tali modelli, nell’ottica di ottenere effetti di regolarizzazione per rumore. Nella seconda parte il problema di regolarizzazione per rumore verrà inquadrato nel contesto più generale di equazioni di evoluzione stocastiche con drift singolare e verranno presentati alcuni risultati di unicità. L'applicabilità di tali tecniche identificherà naturalmente un concetto di criticità che porrà le equazioni doppiamente nonlineari in un regime supercritico. Per queste verrà fornito infine un risultato parziale di stabilità per rumore. I risultati presentati nei seminari sono stati ottenuti in collaborazione con F. Bertacco (Imperial College London) e U. Stefanelli (Università di Vienna). %%%%%%%%%%%%%%%%%%%%%%%%%%%%

seminar - Roberto Ghiselli Ricci
by Sabrina Mulinacci 02 May '25

02 May '25

Dear all, I am glad to announce and invite you to the following seminar Statistics Seminars 2024/2025 Thursday May 8th, 2025 at 14.30 Room IV in Via Belle Arti, 41, Department of Statistics, University of Bologna or online on Microsoft Teams (here below you can find the link) “A world of copulas” Prof. Roberto Ghiselli Ricci (Università Ca‘ Foscari Venezia) Abstract A journey into the most outstanding family of aggregation functions given by the Copulas. They are particularly intriguing, because, on the one hand, they offer a theoretically fertile field of study with deep connections with different branches of mathematics such as Differential Calculus and even Group Theory, and, on the other hand, as consequence of the seminal Sklar's Theorem (1969), they are an essential tool for building refined stochastic models able to satisfy properties required by real problems.

SPASS Seminar: Theodore Drivas
by Mario Maurelli 02 May '25

02 May '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstract below): *Vibrodynamics of constrained mechanical systems* by *Theodore D. Drivas* (Stony Brook University) The seminar will take place on *TUE, 06.05.2025* at *9:00 CEST *(mind unusual 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: Vibrodynamics of constrained mechanical systems* *Abstract: We study the effect of rapid vibration of constraining surfaces of arbitrary codimension on a confined mechanical particle. The slow dynamics experience an effective potential force coming from the geometry of the vibrating surface, which can introduce new equilibria and change stability character of existing ones. A classical example is Kapitza's stabilization of the inverted pendulum with a vibrating pivot. After developing this formalism for finite dimensional systems, we generalize to infinite dimensions by analogy and study the resulting vibrogenic forces for inextensible threads and incompressible fluids. The thread effectively becomes elastic, and the fluid evolves as a variant of the incompressible inhomogeneous system. This is joint work with D. Glukhovskiy.*

Cari colleghi di seguito l'annuncio di un seminario organizzato nell'ambito delle attività dell'IRL LYSM INdAM-CNRS, a cui siete tutti cordialmente invitati a partecipare. ----------------------------------------------------------- LYSeMinar Martedì 6 maggio, ore 10:30, Sala di Consiglio, Dipartimento di Matematica Guido Castelnuovo, Sapienza Università di Roma, P.le A. Moro 5, 00185 Roma Speaker: Lucia Caramellino (Univ. Roma Tor Vergata) Title: Regularization lemmas and applications Abstract: The talk focuses on some regularization results that allow one to prove estimates in the total variation distance, typically by upgrading already known estimates holding in the Wasserstein distance. In all this, tools from Malliavin calculus will play a crucial role. Some applications will then be discussed. The talk is mainly based on the papers "Regularization lemmas and convergence in total variation", with V. Bally and G. Poly (EJP 2020), and "Convergence in Total Variation for nonlinear functionals of random hyperspherical harmonics", with G. Giorgio and M. Rossi (JFA 2024). -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Domenico Marinucci Dipartimento di Matematica Università di Roma Tor Vergata https://sites.google.com/view/domenicomarinucci @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Best wishes, Stefan ------------------------------------------------ Friday, May 09, (12:30 noon London, 1:30 pm Berlin, 2:30 pm Helsinki, 7:30 pm Beijing) in the *International Seminar on SDEs and Related Topics* in Zoom https://jyufi.zoom.us/j/61891007917 *Emmanuel Gobet* (CMAP-Ecole Polytechnique, France) https://users.jyu.fi/~chgeiss/posterofPrEGobet.jpg will speak about *Numerical approximation of ergodic BSDEs using nonlinear* *Feynman-Kac formulas* Abstract: We study the numerical approximation of a class of ergodic Backward Stochastic Differential Equations. In order to build our numerical scheme, we put forward a new representation of the PDE solution by using a classical probabilistic representation of the gradient. Then, based on this representation, we propose a fully implementable numerical scheme using a Picard iteration procedure, a grid space discretization and a Monte-Carlo approximation. Up to a limiting technical condition that guarantees the contraction of the Picard procedure, we obtain an upper bound for the numerical error. We also provide some numerical experiments that show the efficiency of this approach for small dimensions. -- Gianmario Tessitore Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca

Seminars in Statistics at Collegio Carlo Alberto - Marc HOFFMAN (UNIVERSITÉ PARIS-DAUPHINE)
by Matteo Giordano 01 May '25

01 May '25

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 09/05/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Marc HOFFMAN (UNIVERSITÉ PARIS-DAUPHINE) Title: some questions in mathematical statistics linked to evolution PDEs Abstract: Evolution models in applications are often analyzed via PDEs, interpreted as a macroscopic description of the phenomenon of interest. This classical approach is nevertheless challenged by empirical data for model validation, especially when the phenomenon of interest does not depend on well established physical laws. In particular the statistical inference of parameters (estimation and testing) requires an underlying stochastic model. This is usually treated via some addition of noise, sometimes artificially and always a bit arbitrarily. Relying on some specific examples that appear in population biology (cell growth, human demography) or agent-based models in economy, we propose an alternative approach. Starting from a microscopic stochastic model that can be partially observed and for which the PDE of interest is a mean-field limit, the intrinsic statistical noise becomes the fluctuation between the empirical measure of the particle system and the solution of the PDE. We will outline a rigorous statistical program in this setting and will give some results on McKean-Vlasov models that shall emphasize the interest of our approach. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 07/05/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.
