Care tutte, cari tutti, per il prossimo evento del ciclo dei Seminari di Analisi, il 28 Novembre 2024 alle ore 17, in Aula Riunioni, avremo il piacere di ascoltare Michele Gorini (UniPi), che terrà un seminario<https://www.dm.unipi.it/en/seminar/?id=6735d0bcf7cb29212bdb98b2> dal titolo “Convex integration and non-unique solutions in fluid dynamics”. Trovate l'abstract qui sotto. A presto, Ilaria Lucardesi e Luigi Forcella ———————————————————— Dear all, on Thursday 28 November 2024 at 5PM, in "Aula Riunioni", for the Mathematical Analysis Seminar, we will have the pleasure of listening to Michele Gorini (UniPi). The title of the talk<https://www.dm.unipi.it/en/seminar/?id=6735d0bcf7cb29212bdb98b2> is "Convex integration and non-unique solutions in fluid dynamics". Please find the abstract below. See you soon, Ilaria Lucardesi and Luigi Forcella ———————— Speaker: Michele Gorini Title: Convex integration and non-unique solutions in fluid dynamics Abstract: Convex integration is a powerful technique often used to prove existence and non-uniqueness of solutions to PDE systems. In this talk, after introducing the Euler and Navier-Stokes systems of fluid dynamics and the technique itself, we discuss recent results about the fractional Navier-Stokes equations obtained by convex integration. ----------- Luigi Forcella, Assistant Professor (RTD-B, tenure-track) University of Pisa Department of Mathematics Largo Bruno Pontecorvo 5 57127 Pisa, Italy https://pagine.dm.unipi.it/forcella/index.html

Trovate l'abstract qui sotto. Approfittiamo per ricordare che il Professor Titi terrà anche i seguenti seminari presso la SNS: * Lunedì 9, ore 16 in Aula Dini (Palazzo del Castelletto) ci sarà il Colloquio De Giorgi, con una lecture dal titolo "Is dispersion a stabilizing or destabilizing mechanism? Landau-damping induced by fast background flows”. Trovate qui<http://www.crm.sns.it/course/7064/> l’abstract. * Mercoledì 11, ore 15, ci sarà il Seminari della Classe di Scienze, e terrà un talk non tecnico aperto ad un pubblico (anche) non specialistico dal titolo “Mathematics of Turbulent Flows: A Million Dollar Problem!" A presto, Ilaria Lucardesi e Luigi Forcella ———————————————————— Dear all, on Tuesday 10 December at 3 PM, in "Aula Magna", for the Mathematical Analysis Seminar, we will have the pleasure of listening to Edriss Titi (Cambridge).

Please find here<http://www.crm.sns.it/course/7064/> the abstract. * Wednesday 11 December at 3 PM, there will be the non-technical lecture (Seminari della Classe di Scienze) “Mathematics of Turbulent Flows: A Million Dollar Problem!”, addressed to a general science audience. See you soon, Ilaria Lucardesi and Luigi Forcella —————— Speaker: Edriss S. Titi (DAMPT, Cambridge University) Title: Recent Advances Concerning the Navier-Stokes and Euler Equations Abstract: In this talk we will discuss some recent progress concerning the Navier-Stokes and Euler equations of incompressible fluid. In particular, issues concerning the lack of uniqueness using the convex integration machinery and their physical relevance. Moreover, we will show the universality of the critical 1/3 H"older exponent, conjectured by Onsager for the preservation of energy in Euler equations, by extending the Onsager conjecture for the preservation of generalized entropy in general conservation laws. In addition, we will present a blow-up criterion for the 3D Euler equations based on a class of inviscid regularization for these equations and the effect of physical boundaries on the potential formation of singularity. ----------- Luigi Forcella, Assistant Professor (RTD-B, tenure-track) University of Pisa Department of Mathematics Largo Bruno Pontecorvo 5 57127 Pisa, Italy https://pagine.dm.unipi.it/forcella/index.html
